During the first 35 close Titan flybys the Radio and Plasma Wave Science instrument (RPWS) aboard the CASSINI orbiter did not observe radio signals possibly associated with lightning in the atmosphere of Titan [Fischer et al., 2007, Geophys. Res. Lett., 34, L22104). The electric field sensors of the HUYGENS PWA instrument (permittivity, waves and altimetry) observed smooth variations as well as impulsive events varying with altitude during the descent of the probe in the atmosphere of Titan. While a part of the low frequency signals was explained as externally driven Schumann resonances, there is still a debate on the origin of the impulsive events. In order to differentiate natural atmospheric discharges from sources on the parachute or the probe the HUYGENS electric field data have been re-evaluated und combined with probe attitude and velocity. The correlation results indicate that atmospheric electricity phemonena are present in the atmosphere of Titan.

A flux comparison of northern and southern Saturn kilometric radio bursts during southern summer. Planetary Radio Emissions|PLANETARY RADIO EMISSIONS VIII 8|
Mathematics, Physics and Space Research
The energy flux of the northern (N–) and southern (S–) Saturn kilometric radiation (SKR) bursts are statistically compared. We investigated the N– and S–SKR bursts from 2005 DOY 250 to 2006 DOY 200, when Cassini was close to the equatorial plane and RPWS could simultaneously observe both N– and S–SKR. We identified 38 burst events, and compared their flux from southern (summer–side) and northern (winter–side) hemispheres. In the main band (100–400 kHz), S–SKR bursts from the summer–side hemisphere were 5–6 times stronger than the N–SKR bursts from the winter–side. This is not far from the flux ratio in the non-burst status. In the low-frequency extension (10–50 kHz) of SKR bursts, this ratio is smaller, about 2–3 times.

Exo-lightning radio emission: The case study of HAT-P-11b. Planetary Radio Emissions|PLANETARY RADIO EMISSIONS VIII 8|
Mathematics, Physics and Space Research
Lightning induced radio emission has been observed on solar system planets. Lecavelier des Etangs et al. [2013] carried out radio transit observations of the exoplanet HAT-P-11b, and suggested a tentative detection of a radio signal. Here, we explore the possibility of the radio emission having been produced by lightning activity on the exoplanet, following and expanding the work of Hodos´an et al. [2016a]. After a summary of our previous work [Hodos´an et al. 2016a], we extend it with a parameter study. The lightning activity of a hypothetical storm is largely dependent on the radio spectral roll–off, n, and the flash duration, τfl. The best–case scenario would require a flash density of the same order of magnitude as can be found during volcanic eruptions on Earth. On average, 3.8×106 times larger flash densities than Earth–storms with the largest lightning activity are needed to produce the observed signal from HAT-P-11b. Combined with the results of Hodos´an et al. [2016a] regarding the chemical effects of planet–wide thunderstorms, we conclude that future radio and infrared observations may lead to lightning detection on planets outside the solar system.

Rapid progress currently takes place in the field of low-frequency radio astronomy in the meter–decameter–hectometer range of wavelengths. It is caused by a radical modernization of the existing radio telescopes, creation of a new generation of instruments, space-borne observations, and by the development of research on all classes of astrophysical objects, including the Solar System. On the other hand, a range of difficulties specific to low-frequency radio astronomy is known, which are caused by technical, methodological, and physical limitations. An effective strategy for overcoming these difficulties is based on synchronous observations using several radio telescopes separated by distances from a few to several thousand kilometers. This provides an opportunity to reduce and identify radio interference and the influence of the propagation media, to increase the sensitivity and resolution, and to solve many problems with higher efficiency. In recent years such simultaneous observations were carried out for the Sun, Jupiter, Saturn, interplanetary medium, pulsars, exoplanets, and transients using the radio telescopes UTR-2, URAN, GURT, NDA, NenuFAR, LOFAR and other. Parallel observations with the space missions WIND, STEREO, Cassini and Juno also facilitate improvement of the quality and reliability of low-frequency radio astronomical experiments.

New Type of Periodic Bursts of Non-Io Jovian Decametric Radio Emission. Planetary Radio Emissions| PLANETARY RADIO EMISSIONS VII 7|
Rucker, H. O.
Panchenko, M.
Mathematics, Physics and Space Research
Analyzing the data acquired by STEREO/WAVES,Wind/WAVES and Cassini/ RPWS instruments during the time interval between the years 2002-2010 we have revealed unusual periodic radio bursts of the non-Io controlled component of the Jovian decametric radiation (non-Io DAM). These non-Io bursts are typically observed in a frequency range from ~ 5 MHz up to ~ 10–16 MHz and recur during several Jovian days with a surprisingly new period of ~ 10.07 hours. This period is 1.5% longer than the rotation period of the inner Jovian magnetosphere (System III, 9.925 hour). The occurrence probability of these periodic bursts has been found to be significantly higher in the sector of Jovian Central Meridian Longitude between 300? and 60? (via 360?), corresponding to the region of non-Io-C sources. Stereoscopic observations performed by STEREO/WAVES as well as Wind/WAVES and Cassini/RPWS suggest that the sources of the periodic bursts sub-corotate with Jupiter. The relations between the occurrence of the periodic bursts and solar wind activity have been analyzed.

The Saturnian Kilometric Radiation before the Cassini Grand Finale. Planetary Radio Emissions|PLANETARY RADIO EMISSIONS VIII 8|
Mathematics, Physics and Space Research
The Saturnian Kilometric Radiation (SKR) is radiated from the auroral regions surrounding the Kronian magnetic poles, above the ionosphere up to a few planetary radii. It directly compares to the auroral radio emissions emanating from other planetary magnetospheres such as Earth and the giant planets. Our knowledge on SKR relied on remote observations of the Voyagers (flybys in 1980 and 1981) and Ulysses (distant observations in the 1990s) until Cassini started to orbit Saturn in 2004. Since then, it has been routinely observed from a large set of remote locations, but also in-situ for the first time at a planet other than Earth. This article reviews the state of the art of SKR average remote properties, the first insights brought by in-situ passes within its source region, together with some remaining questions before the Cassini Grand Finale and its close-in polar orbits.

Jovian decametric emission with the Long Wavelength Array station 1 (LWA1). Planetary Radio Emissions|PLANETARY RADIO EMISSIONS VIII 8|
Mathematics, Physics and Space Research
The Long Wavelength Array Station 1 (LWA1) is located in central New Mexico, USA. It consists of 256 pairs of ‘droopy–dipole’ antennas operating between 10 and 88 MHz. The antennas are distributed in a pseudo–random layout across a 110 m × 100 m region. Observations with the LWA1 are based on peer reviewed proposals for open–skies observing time. LWA1 is an excellent planetary radio emission instrument due to its sensitivity and the low radio frequency interference environment where it is located. We have undertaken several Jovian observing campaigns using the LWA1. We show that LWA1 data provide excellent spectral detail in Jovian decametric emission such as simultaneous left hand circular (LHC) and right hand circular (RHC) polarized Io-related arcs and source envelopes, modulation lane features, S-bursts structures, narrow band N-events, and apparent interactions between S-bursts and N-events. The start of the LHC Io-C source region was traced to earlier longitudes than typically found in the literature. Early LWA1 observations revealed a wealth of Io-D emission, including detection of rare S-bursts during an Io-D event. These initial results have led to new programs to explore the spectral characteristics of Io-D events, investigate modulation lanes of Io-B/Io-C events and examine the beaming structure of S-bursts combining LWA1, NDA, and URAN2. In addition, LWA1 is one of the ground-based support facilities for the NASA JUNO1 mission.

Io-Jupiter Electrodynamic Interaction, Electron Acceleration and Radio Bursts Generation (abstract). Planetary Radio Emissions| PLANETARY RADIO EMISSIONS VII 7|

Mathematics, Physics and Space Research
Radio emissions from the Io-Jupiter electrodynamic circuit are structured in discrete bursts, quasi-periodic (5-10 Hz), and with drifting frequency versus time (df/dt<0). High temporal and spectral radio spectrometry, associated to numerical simulations (PIC=Particle-In-Cell) allowed us to study in details the acceleration processes of the electrons responsible for the emissions. We computed the acceleration of ambient electrons within the Io Flux Tube (IFT) by an Alfv´en wave excited by Io crossing Jupiter’s magnetic field lines. Then we computed the Cyclotron-Maser radio emission generated by the resulting electron populations. The time-frequency structure of these emissions is very similar to those observed. The detailed analysis of the bursts shape in the time-frequency plane (df/dt) allowed us to discover the existence of electric potential drops (= double-layers, ~1 kV) aligned with the IFT magnetic field. Such acceleration structures, observed in-situ above the Earth’s auroral regions, were unknown at Jupiter. Furthermore, high resolution radio spectroscopy allowed us to study these structures on the long-term (minutes to hours), and we showed that they are moving upwards at the local sound speed. Finally, taking into account these acceleration structures in addition to Alfv´en waves in our numerical simulations, we succeeded in reproducing in details the complex timefrequency morphology observed for many ra- dio bursts. We present recent studies on large-scale solar coronal waves (so-called ”EIT waves”) obtained with the EUVI instruments onboard the twin STEREO spacecraft. EUVI has several advantages for coronal wave studies: a) high cadence full-disk imaging, which allows us to catch the wave evolution and kinematics, b) a large field-of-view, which allows simultaneous observations of the erupting CME, and c) observations from two vantage points, which enable us to get insight into the three-dimensional structure of the wave. The present understanding is basically split into different groups of ”wave” versus ”nonwave” interpretations of the physical process behind the phenomenon, as well as ”flare” versus ”CME” for the driving agent. We will present the first observations of the full three-dimensional wave dome in the event of January 17, 2010. The study of the perturbation characteristics and the associated high-frequency radio type II bursts provide evidence for a weakly shocked fast-mode wave as the underlying physical process.

The high-frequency electric sensors onboard Solar Orbiter are part of the radio and plasma wave experiment (RPW). The sensors consist of cylindrical antennas (ANT) mounted on three booms extruded from the central body of the spacecraft. Due to the parasitic effects of the conducting spacecraft body and solar panels the true antenna properties (effective axes and length, capacitances) do not coincide with their physical representations. The numerical analysis of the reception properties of these antennas is presented. In order to analyze the antenna system we applied a numerical method. The current distribution on the spacecraft body and the effective length vector was calculated, by solving the underlying field equations using electromagnetic code. In the applied method the spacecraft is modeled as a mesh-grid.

Mathematics, Physics and Space Research
The present state of solar wind investigations by IPS (interplanetary scintillations) observations at decameter wavelengths is discussed. Radio telescopes, equipment and methods which are used in these experiments are shown. We also describe some interesting results devoted to the long term monitoring of the solar wind beyond Earth’s orbit, the detection of the large scale disturbances associated with active processes at the Sun and the reconstructions of the solar wind stream structure. Emphasis is placed on perspectives of low frequency IPS investigations which are particularly connected with the creation of the Giant Ukrainian Radio Telescopes (GURT) and UTR-2 – URAN – GURT – LOFAR collaboration.

S-component of the sporadic radio emission of Jupiter decameter emission (DAM) is an extraordinary astrophysical phenomenon which is formed as the result of a unique interaction between the Jupiter and its Io satellite and this phenomenon is characterized by an unusual complexity of the frequency-temporal structure on the dynamic spectra. The Jovian S-burst emission appears during the decameter radio storms which can be predicted on the basis of the analysis of the geometric configuration between the Earth, the Jupiter and Io. Monitoring of the Io-dependent DAM emission revealed the characteristic Jupiter emission zones known as Io-A, Io-B, Io- C, and Io-D. It should be noted that despite of more than 50 years of extensive exploration of the Jovian DAM radiation the physical nature of this phenomenon remains insufficiently clear. On the other hand, many problems in the theory of the Jovian decameter emission have been successfully investigated and solved [Litvinenko et al., 2004; Zaitsev et al., 2006; Ladreiter et al., 1995; Shaposhnikov et al., 1997, 2011]. Nevertheless, there is reason to believe that not all issues concerning the physical nature of this unique phenomenon have been definitively resolved. One of the perspective approaches for finding new results is experimental investigation at a higher quality and quantity level followed by a detailed data analysis using both well known and modern mathematical methods. Development of the receiving equipment (improvement of the following characteristics: the temporal-frequency resolution, sensitivity, signal-to-noise ratio, etc.) allows to analyze the specific Sburst features from the microscopic to macroscopic scale [Litvinenko et al., 2009]. With this aim several observational campaigns were performed in November 2009 using the UTR-2 radio telescope (Kharkov, Ukraine) and effective registration systems possessing high frequency and temporal resolutions (antenna effective area is close to 100,000 m2, the frequency resolution is 4 kHz, the temporal resolution is 0.25 ms, the dynamic range is 70 dB) [Konovalenko et al., 2001]. The main goal of these campaigns was an experimental investigation of the Jovian decameter radio emission with an attempt to find out and analyse the phenomena which can be detected using the above mentioned equipment.

Mathematics, Physics and Space Research
The ExoMars 2020 Surface Platform will conduct environmental and geophysical measurements with the aim of studying the Martian surface and subsurface environment at the landing location. The Surface Platform instrumentation will include the Wave Analyzer Module (WAM) as a European contribution to the Russian–led Martian ground electromagnetic tool (MAIGRET) instrument. The wave analyzer module will be dedicated to measurements of magnetic field fluctuations in the frequency band from 100 Hz to 20 kHz. The scientific questions which we plan to address by measurements of the WAM have never been answered by direct measurements of the fluctuating magnetic fields in the appropriate range of frequencies directly on the surface of the planet. The immediate questions related to these targets are: 1. Can we observe electromagnetic radiation from electric discharges in the Martian dust storms? 2. Can we observe electromagnetic radiation propagating from the interplanetary space down to the surface of the planet?

Mathematics, Physics and Space Research
Several complex uncommon zebra patterns in meter/ decimeter and microwave range are shown. It is difficult to interpret them as the regular harmonics within the framework of known models, e.g. based on the double plasma resonance (DPR) mechanism. Specifically, for this reason, only in the last 5 years about 10 works devoted to an improvement of the DPR mechanism were published, and 5 new models were proposed. We propose a new advanced model of ZP based on the explosive instability in the system of the weakly-relativistic mono-velocity beam of protons - the strongly nonisothermic plasma.

Khodachenko, M. L.
Antonov, O. V.
Arkhypov, O. V.
Mathematics, Physics and Space Research
The global distribution of solar surface activity (active regions) is connected with processes in the convection zone. To extract the information on large-scale motions in the convection zone, we study the solar synoptic charts (Mount Wilson 1998-2004, Fe I, 525.02 nm). The clear indication of large-scale (= 18°) turbulence is found. This may be a manifestations of the deep convection because there is no such global turbulent eddies in the solar photosphere. The preferred scales of longitudinal variations in surface solar activity are revealed. These correspond to ~ 15° to 51° (gigantic convection cells), 90°, 180° and 360°. Similar scales (e.g., 40° and 90°) are found in the millimeter radio-images (Mets¨ahovi Radio Observatory 1994-1998, 37 and 87 GHz). Hence, the millimeter radio astronomy could prove useful for remote sensing of the solar convection zone.

Insight into atmospheres of extrasolar planets through plasma processes. Planetary Radio Emissions|PLANETARY RADIO EMISSIONS VIII 8|
Mathematics, Physics and Space Research
Extrasolar planets appear in a chemical diversity unseen in our own solar system. Despite their atmospheres being cold, continuous and transient plasma processes do affect these atmosphere where clouds form with great efficiency. Clouds can be very dynamic due to winds for example in highly irradiated planets like HD189733b, and lightning may emerge. Lightning, and discharge events in general, leave spectral fingerprints, for example due to the formation of HCN. During the interaction, lightning or other flash–ionization events also change the electromagnetic field of a coherent, high energy emission, which results in a characteristic damping of the initial, unperturbed (e.g. cyclotron emission) radiation beam. We summarize this as ’recipe for observers’. External ionization by X-ray or UV e.g. from within the interstellar medium or from a white dwarf companion will introduce additional ionization leading to the formation of a chromosphere. Signatures of plasma processes therefore allow for an alternative way to study atmospheres of extrasolar planets and brown dwarfs.

An SLS4 Longitude System Based on a Tracking Filter Analysis of the Rotational Modulation of Saturn Kilometric Radiation. Planetary Radio Emissions| PLANETARY RADIO EMISSIONS VII 7|

Mathematics, Physics and Space Research
Saturn has been known for over thirty years to emit an intense radio emission at kilometer wavelengths called Saturn Kilometric Radiation (SKR) that is modulated by the rotation of the planet. Although the period of this modulation was initially thought to represent the rotation period of the planet, it is now known that the radiation has two distinctly different rotational modulation periods that vary by on the order of one percent on times scales of years. One component originates primarily from the northern auroral region, and the other originates primarily from the southern auroral region. The differences in the modulation periods are believed to be due to latitudinal variations in the slippage of the magnetosphere relative to the interior of planet, apparently controlled by the seasonal variation in the tilt of Saturn’s rotational axis. Since other magnetospheric phenomena display similar complicated rotational modulation effects, there is a need to define north and south longitude systems based on the variable SKR modulation periods in the two hemispheres. Because the SKR signal received by the spacecraft often includes both components it is sometimes difficult to separate the phases of the two components. In this paper we describe a method of determining the two phases based on a tracking filter approach that can separately track the modulation waveforms of the two components. The phases of the two waveforms can then be used to define a new longitude system for the northern and southern components that we call the SLS4 longitude system. This is an extension of the previous SLS2 and SLS3 longitude systems, which only described phase variations of the southern component.

The search for radio emission from giant exoplanets. Planetary Radio Emissions|PLANETARY RADIO EMISSIONS VIII 8|
Mathematics, Physics and Space Research
The intensity of Jupiter’s auroral radio emission quickly gave rise to the question whether a comparable coherent emission from the magnetosphere of an extrasolar planet could be detectable. A simple estimation shows that exoplanetary auroral radio emission would have to be at least 1000 times more intense than Jupiter’s emission to be detectable with current radio telescopes. Theoretical models suggest that, at least in certain cases, the radio emission of giant exoplanets may indeed reach such an intensity. At the same time, in order to generate such an emission, an exoplanet would need to have a sufficiently strong intrinsic planetary magnetic field. Extrasolar planets are indeed expected to have a magnetic field, but to date, their magnetic field has never been detected. As discussed elsewhere [Grießmeier et al., 2015], the most promising technique to unambiguously observe exoplanetary magnetic fields is to search for the planetary auroral radio emission. The detection of such an emission would thus constitute the first unambiguous detection of an exoplanetary magnetic field. We review recent theoretical studies and discuss their results for the two main parameters, namely the maximum emission frequency and the intensity of the radio emission. The predicted values indicate that detection should be possible using modern low-frequency radio telescopes. We also review past observation attempts, and compare their sensitivity to the predicted emission.

Unusual Type III Bursts at the Decametre Wavelengths. Planetary Radio Emissions| PLANETARY RADIO EMISSIONS VII 7|

It is currently accepted that the dependences of frequency drift rate and instant duration of type III bursts on frequency follow a monotonic function. The observations carried out during summer months of 2002-2006 by the world largest decameter wavelength radio telescope UTR-2 in frequency band 10-30 MHz show that sometimes these dependences may have a jump at some frequency, when the steepness of the dependence changes step-wise. In this paper the results of observations of such unusual type III bursts are given. Since the dynamic spectrum of such bursts resembles a dog’s leg we call them “dog-leg” type III bursts. More than a hundred of these “dog-leg” bursts were observed during 5 years. The parameters of the 41 bursts observed in 2002 were defined and statistically analyzed. The fact that “dog-leg” type III bursts are observed on the background of standard type III bursts allows to exclude any instrumental component of the observed phenomena.

The paper deals with interpretation of long-periodic (minutes, e.g. < 0.01 Hz) modulations, detected in the microwave records during flaring events on the Sun, as the signatures of large scale transverse oscillations of coronal loops, observed at the same time by TRACE. In the case of transverse large scale oscillatory motions of a loop a properly located observer, besides of the modulation caused by motion of the emission diagram pattern at the main oscillation frequency, may see also a modulation at double frequency of the loop oscillation, resulted by a varying magnetic field during each inclination of the loop, as well as weaker higher harmonics. Identification of such ”modulation pairs” in the dynamic spectra of solar microwave emission and their association with the observed oscillating coronal loops form the major result of the undertaken investigation. Three different events with the detected by TRACE post-flare oscillating loops were considered in that study (Mar.23,2000; Sep.15,2001; Sep.07,2001).

Intense saturnian radio emission has been observed since June 2004, and until today, by the Radio and Plasma Waves Experiment (RPWS) on board Cassini spacecraft. During this long period of about six years the spacecraft was orbiting principally in the planetary equatorial plane. However in 2007 and 2008 orbits reach latitudes higher than 50? which lead us to investigate sub-auroral saturnian radio emissions. In this study we examine the spectral distinctions between the saturnian radio emissions observed in the equatorial plane and those in latitudes close to the southern and northern auroral regions. We consider the three components reported by Galopeau et al. [2007, J. Geophys. Res., 112, A11213] principally dominated by the so-called saturnian kilometric radiation (80 kHz - 900 kHz). We analyze the occurrence probability of these components taking into consideration different geometric configurations between the spacecraft, the planet and the Sun. We discuss the spectral alteration and change, from the equatorial plane to the high latitudes, of Saturnian radio emissions. Also we examine the spectral distinction between the radio emissions emitted from the northern and southern hemispheres, in particular in the case of the saturnian kilometric radiation (SKR). Our results are discussed and compared with those already reported in the literature dealing with the Voyager and the Cassini missions.

In this paper, test results from a 25-element active antenna prototype array operating in the frequency range of 10–70 MHz are presented. Observations of radio emission from different sources: solar sporadic radio emission and powerful cosmic radio sources including their ionosphere scintillation, demonstrate the high effectiveness of the system due to the Galactic background limited sensitivity and high dynamic range of the antenna amplifier (noise immunity). This demonstrates the capability of this 25-element active antenna array to engage in a wide range of unique wide band radio astronomical observations of solar system objects that do not require high sensitivity and angular resolution.

Analysis of Jovian low-frequency radio emissions based on stereoscopic observations with Juno and Earth-based radio telescopes. Planetary Radio Emissions|PLANETARY RADIO EMISSIONS VIII 8|
Mathematics, Physics and Space Research
Observations of Jupiter’s low-frequency radio emissions were made using the radio and plasma wave instrument (Waves) onboard the Juno spacecraft in polar orbit around Jupiter since July 5, 2016. Waves is designed to monitor the electric fields of waves from 50 Hz to 41 MHz with an electric dipole antenna and the magnetic fields of waves from 50 Hz to 20 kHz with a magnetic search coil sensor. The Juno spacecraft rotates with a period of 30 s, which modulates the spectral intensity sensed with the dipole antenna. We report early results of the Juno Waves investigation on (1) the direction–finding measurements of broadband kilometric (bKOM) radiation just before Juno’s first perijove, (2) one concurrent decametric (DAM) radiation from the Juno spacecraft near Jupiter and the Nan¸cay Decameter Array in France during Juno’s interplanetary cruise, and (3) the statistical properties of Jovian DAM radio occurrence probability at 16 MHz obtained from Juno data of June 21 to December 10, 2016, then compared with the previous statistical results of the Cassini and Voyager observations during their Jupiter flybys.

It has long been recognized that there is a marked long-term periodic variation in Jupiter’s integrated radio occurrence probability. The period of the variation is on the order of a decade. Carr et al. [1970] showed that such variations are closely correlated with Jovicentric declination of the Earth (DE). The range of the smoothed variation of DE is from approximately +3.3 to -3.3 degrees. This DE effect was extensively studied and confirmed by Garcia [1996]. It shows that the occurrence probability of the non-Io-A source is clearly controlled by DE at 18, 20, and 22 MHz during the 1957-1994 apparitions. We propose a new model to explain the DE effect. This new model shows that the beam structure of Jupiter radio emissions, which has been thought of like a hollow-cone, has a narrow beam like a searchlight, which can be explained by assuming that the three dimensional shape of the radio source expands along the line of the magnetic field. If we consider the sizes of the radio coherent region are 1000 m along Jupiter’s magnetic field line and 200 m along the latitudinal direction, the equivalent beam pattern is 1 degree wide along Jupiter’s magnetic field line and 5 degrees in latitude. As the searchlight beam is fixed with Jupiter’s magnetic field, the pure geometrical effect of DE can be explained by this searchlight beam model.

Numerical Simulation of the Propagation of Type III Radio Emission. Planetary Radio Emissions| PLANETARY RADIO EMISSIONS VII 7|
Rutkevych, B.
Melnik, V. N.
Mathematics, Physics and Space Research
Recently solar Type III bursts with fine time structure have been observed by radio telescope UTR-2 at frequencies 10 - 30 MHz. For the first time Type III-like bursts with high frequency drift rates were observed at these frequencies too. All this became possible due to both high sensitivity and high time resolution of UTR- 2. The properties of decameter Type III bursts can be understood if we take into account the spatial dependence of the electromagnetic wave group velocity as well as the fine spatial structure of the cloud of fast electrons responsible for Type III bursts. These effects are considered numerically in this paper. The fine time structure of Type III bursts is shown to be observed in the days when the associated active region is situated near the central meridian. In other days such structures disappeared. The Type III-like bursts with frequency drift rates of 10 - 20 MHz/s should also be observed, when the associated active region is near the central meridian. These peculiarities are confirmed by observations.

Mathematics, Physics and Space Research
Voyager/PRA (Planetary Radio Astronomy) data from digitized tapes archived at CNES have been reprocessed and recalibrated. The data cover the Jupiter and Saturn flybys of both Voyager probes. We have also reconstructed goniopolarimetric datasets (flux and polarization) at full resolution. These datasets are currently not available to the scientific community, but they are of primary interest for the analysis of the Cassini data at Saturn, and the Juno data at Jupiter, as well as for the preparation of the JUICE mission. We present the first results derived from the re-analysis of this dataset.

In this paper properties of decameter spikes observed in July - August, 2002 by radio telescope UTR-2 are discussed. These bursts have short duration (about 1s) and narrow frequency bandwidth (50 - 70 kHz). They are situated chaotically on the dynamic spectrum at the decameter wavelengths. These bursts are weak, their fluxes are not higher than 200 - 300 s.f.u. One of the interesting features of decameter spikes is linear dependence of frequency bandwidth on frequency. Such dependence can be explained in the frame of plasma mechanism of radio emission if to take into account that Langmuir waves are generated into the angle about 20 deg along the direction of electron beam propagation. In the paper the cause of small duration of spikes and generation of plasma waves in limited spatial regions are discussed.

On 17 October 2008, the Cassini spacecraft crossed the southern sources of Saturn kilometric radiation (SKR), while flying along high-latitude nightside magnetic field lines. In situ measurements allowed us to characterize for the first time the source region of an extra-terrestrial auroral radio emission. Using radio, magnetic field and particle observations, we characterize the plasma environment surrounding the SKR sources. Magnetic field lines supporting local as well as distant radio sources (detected on both extraordinary and ordinary modes) map a continuous, high-latitude and spiral-shaped unusual auroral oval observed on the dawnside, consistent with enhanced auroral activity. While investigating the Cyclotron Maser Instability (CMI) as a mechanism responsible for SKR generation, we find that observed cutoff frequencies are consistent with radio waves amplified perpendicular to the magnetic field by hot (6 to 9 keV) resonant electrons, measured locally. Finally, we confirm and quantify previous observations of the SKR elliptical polarization, found to evolve toward circular polarization with the distance to the source.

The Auroral Kilometric Radiation (AKR) was investigated on measurements in the POLRAD experiment on the INTERBALL-2 satellite. It was revealed ”lowfrequency” radiation with specific features in a spectrum on a polar edge of the auroral region. We have obtained that a series of narrow-band splashes are observed at frequencies between 35 and 70 kHz with the period modulation some tens seconds and bow-shaped envelope. Possible interpretation of emission generation with a specific spectrum is discussed. We suppose that increase of intensity at small frequencies is interpreted as crossing by the satellite of the source region and observation of waveguide modes within it.

Plasma Heating by the Parametric Excitation of Acoustic Waves in Coronal Magnetic Loops. Planetary Radio Emissions| PLANETARY RADIO EMISSIONS VII 7|
Kislyakova, K. G.
Zaitsev, V. V.
Mathematics, Physics and Space Research
When studying microwave emission of active regions on the Sun, an effect of parametric resonance between 5-min velocity oscillations in the solar photosphere and sound oscillations of coronal magnetic loops modulating the microwave emission has been discovered for the first time. The effect shows itself as simultaneous excitation in coronal magnetic loop oscillations with periods 5, 10, and 3 min, which correspond to the pumping frequency, subharmonic, and the first upper frequency of parametric resonance. The parametric resonance can serve as an effective channel of transporting the energy of photospheric oscillations into the upper layers of the solar atmosphere. The energy of acoustic waves excited in a coronal magnetic loop, rate of dissipation of acoustic waves, and rate of heating of the coronal plasma are determined. The maximum temperature predicted for the apex of the loop is calculated as a function of velocity of photospheric oscillations, length of the loop, and electric current in the loop. It is shown that the mechanism proposed can explain the origin of quasi-stationary X-ray loops with temperatures of 3-6 MK. The lengths of these loops are resonant for acoustic waves excited by the 5-min photospheric oscillations. The use of the proposed mechanism to explain heating of the X-ray loops expected to be on stars of late spectral types is discussed.

Rubab, N.
Mathematics, Physics and Space Research
Dust kinetic Alfv´en waves (DKAW) instability with ?-distributed ions streaming effects have been examined rigorously in a uniform dusty magnetoplasma. A dispersion relation of low-frequency DKAW instability on the dust acoustic velocity branch is obtained in a low-ß Lorentzian plasma. It is found that nonthermality is more effective for dust kinetic Alfv´en waves in the perpendicular component having finite larmor radius effects. Lorentzian type charging currents are obtained with the aid of Vlasov theory. Effect of different dust parameters on the growth rates of instability are considered. Damping/instability due to dust charge fluctuation is found to be insensitive to the form of the distribution function for DKAW. Possible applications to dusty space plasmas are pointed out.

According to the special Program of the National Academy of Sciences of Ukraine, creation of the new giant Ukrainian radio telescope (GURT) was started a few years ago on the UTR-2 radio telescope observatory. The main goal is to reach maximum band at the lowest frequencies (10-70 MHz), effective area (step-by-step up to 100,000 sq.m), and high interference immunity for resolving many astrophysical tasks when the sensitivity is less limited by the confusion effects. These tasks include stellar radio astronomy (the Sun, solar wind, flare stars, pulsars, transients) and planetary one (Jupiter, planetary lightnings, Earth ionosphere, the Moon, exoplanets). This array should be complementary to the LOFAR, E-LOFAR systems. The first stages of the GURT (6 x 25 cross-dipole active elements) and broad-band digital registration of the impulsive and sporadic events were tested in comparison with the existing largest decameter array UTR-2.

Solar Wind and Saturnian Moons Signatures in the Long-Periodic Modulations of SKR (abstract). Planetary Radio Emissions| PLANETARY RADIO EMISSIONS VII 7|

Long-periodic (LP) modulations of intensity of Saturnian Kilometric Radiation (SKR) recorded by RPWS instrument onboard Cassini spacecraft were studied by means of a combined data analysis algorithm based on a ”sliding window” Fourier (SWF) procedure and the nonlinearWigner-Ville (WV) method. The analyzed SKR data record covers the years 2004-2005. It has been found that SKR has well pronounced impulsive modulation, with quasi-periodic pulses appeared approximately each 10.74 hours and having duration of about 5 hours. The period of pulses, in spite of the overall stability, has sometimes the disturbances within the interval of 10.74 - 10.76 hours. By this, the whole impulsive modulation of SKR appeared in 2004-2005 in a form of quasi-regularly repeated modulation activity storms. Time interval between the adjacent modulation activity storms most often was within 8-13 days. Altogether, 55 impulsive modulation activity storms were registered during 2004-2005. Besides of the storms of 10.7 h pulses, the intensity of SKR has several more long periodic modulations. In particular, ~6-7 days, ~8-9 days, ~12-13 days and ~25-27 days components were detected. These are connected probably with the quasi-regular character of the storms of 10.74 h pulses. While the origin of 10.74 hour pulses can be associated with the rotation of Saturn, the long periodic modulation features are very likely connected with the detected similar variations of the solar wind parameters. The last in their turn may be caused by the varying solar surface magnetic activity and rotating streams of high speed solar wind. Besides of that, the performed analysis shows that some Saturnian moons may also have influence on the intensity of SKR. In particular, specific modulations with periods corresponding to orbital motions of close moons (Enceladus, Tethys) as well as Titan, Hyperion and Dione were detected.

Coronal Mass Ejections and Solar Radio Emissions (invited). Planetary Radio Emissions| PLANETARY RADIO EMISSIONS VII 7|
Gopalswamy, N.

Three types of low-frequency nonthermal radio bursts are associated with coronal mass ejections (CMEs): Type III bursts due to accelerated electrons propagating along open magnetic field lines, type II bursts due to electrons accelerated in shocks, and type IV bursts due to electrons trapped in post-eruption arcades behind CMEs. This paper presents a summary of results obtained during solar cycle 23 primarily using the white-light coronagraphic observations from the Solar Heliospheric Observatory (SOHO) and the WAVES experiment on board Wind.

Interpretation of whistler mode chorus observations with the backward wave oscillator model. Planetary Radio Emissions|PLANETARY RADIO EMISSIONS VIII 8|
Mathematics, Physics and Space Research
Observations of whistler–mode chorus made by the THEMIS spacecraft inside the equatorial chorus source region often exhibit the following peculiar features. Two groups of chorus elements are visible simultaneously which are approaching the spacecraft from two different directions: either along or against the direction of the ambient magnetic field. Furthermore, both groups are slightly shifted in frequency with respect to each other and elements are of different intensities. We interpret these features in the frame of the backward–wave oscillator theory by means of two exemplary events, yielding insight into the nonlinear generation mechanism and the specific source–observer geometry during the time of observation.

Radio manifestation of the CME observed on April 7, 2011 in the frequency band 8-32 MHz. Planetary Radio Emissions|PLANETARY RADIO EMISSIONS VIII 8|
Mathematics, Physics and Space Research
On April 7, 2011 a CME was observed originating above the AR NOAA 1176, located behind the solar limb. This CME was associated with type IV burst, type II bursts and groups of J-bursts and type III bursts. Groups of J-bursts and type III bursts were observed from 10:50 to 11:20 UT. There was a group of J-bursts from 10:52 to 10:57 UT, originating from accelerated electrons propagating along high magnetic loops connected with the active region NOAA 1176. The group of type III bursts continued from 11:00 to 11:20 UT. There were a lot of spikes and type IIIb bursts with polarizations up to 80% during the group of type III bursts. Type IV burst began at 11:20 UT at 32 MHz and continued for more than 3 hours. Its maximum flux was about 200 s.f.u., and the polarization achieved 40%. There were 3 type II bursts superimposed by type IV burst. Their drift rates were approximately 0, 10 kHz/s, 25 kHz/s, and it appears that they were radio emissions from different regions of the spherical shock produced by the CME. All type II bursts consisted of tadpoles with ”heads” and ”tails”. Their durations were 4 s and 2 s, and their polarizations were about 10% and 40%, correspondingly. The frequency bands of the ”tails” was up to 10 MHz. Their frequency drift rates could be positive and negative ones, and their absolute values changed from 0.4 MHz/s to 4 MHz/s. Previously we found that decameter type IV bursts oscillated with periods of tens of minutes. The type IV burst observed on April 7, 2011 showed oscillations also. Fourier and wavelet analyses showed periods of about 40 minutes for both fluxes and polarizations. Moreover, it turned out that these periods decreased with time with rates of 0.03–0.07. Interpretations of all decameter phenomena are discussed.

Solar Radio Emissions in View of the Solar Orbiter Mission (invited; abstract). Planetary Radio Emissions| PLANETARY RADIO EMISSIONS VII 7|
Maksimovic, M.
Mathematics, Physics and Space Research
One of the science goals of the Solar Orbiter mission is to study the connectivitybetween the solar corona and the inner Heliosphere as close as from 0.3 AU. Withthis respect the study of Solar radio emissions produced energetic electrons eitherflare or shock accelerated will be of prime importance. I will first review some recentfindings obtained with the help of Ulysses, WIND and Stereo observations. I willthen present the expected capabilities of the Solar Orbiter instrumentation relevantto the discussed topic.

Zebra-like fine spectral structures in Jovian decametric radio emission. Planetary Radio Emissions|PLANETARY RADIO EMISSIONS VIII 8|
Mathematics, Physics and Space Research
We report the first systematic analysis of zebra–like fine spectral structures in the decametric frequency range of Jovian radio emission (DAM). These zebra patterns are observed in the frequency range from 12 to 30 MHz as a quasi-harmonically related bands (from 3 to 9) of enhanced brightness. The features have been observed by the ground-based radio telescope URAN-2 (Poltava, Ukraine). In total, 55 zebra pattern events have been detected during the period from September 2012 to March 2016. The minimum duration of one single zebra pattern was 20 s, and the maximum one was 4 min 50 s. The intensity of the zebra stripes is 1–2 magnitudes lower than the intensity of Io–controlled DAM. The numbers of stripes in one event may vary in time. The frequency interval between neighboring stripes is from 0.26 to 1.5 MHz. The zebra patterns are strongly polarized and have been observed as right-handed and left-handed polarized radio emission. The zebra patterns are mainly detected in two active sectors of Jovian CMLs: 100° to 160° for northern sources (righthanded polarized) and between 275° and 60° (via 360°) for the southern sources (left-handed). No correlation with the position of Io has been detected. We conclude that the observed zebra patterns are a new type of narrow band spectral structures in the Jovian decametric radio emission.

HeRO: A space-based low frequency interferometric observatory for heliophysics enabled by novel vector sensor technology. Planetary Radio Emissions|PLANETARY RADIO EMISSIONS VIII 8|
Mathematics, Physics and Space Research
HeRO (Heliophysics Radio Observer) is a hybrid ground and space mission concept for radio interferometry of solar radio bursts. The space segment (HeRO-S) covers low frequencies, 100 kHz–20 MHz, and is composed of 6 free–flying Cube- Sats equipped with vector sensors. The ground segment (HeRO-G), covers higher frequencies, 15 MHz–300 MHz. HeRO will explore conditions and disturbances in a key region of the heliosphere, from two to tens of solar radii, using interferometric observations of solar radio bursts over three decades in frequency. Spot mapping across the full frequency range will provide precise positions and basic structural information about type II and III radio bursts. The morphology of CME shock fronts will be traced via type II burst emissions, and heliospheric magnetic field geometries will be probed by measuring precise trajectories of type III bursts. Refraction in the heliospheric plasma on large and intermediate scales will be investigated throughout large volumes via the frequency dependence of accurate interferometric positional data on bursts. The HeRO data will be information rich with high resolution in time, frequency and spatial position, and high SNR, creating fertile ground for discovery of new phenomena.

Coronal Magnetic Field Structure in Solar Active Regions. Planetary Radio Emissions| PLANETARY RADIO EMISSIONS VII 7|
Stupshin, A. G.
Yasnov, L. V.
Bogod, V. M.
Mathematics, Physics and Space Research
We analyzed the structure of the magnetic field in active regions at coronal altitudes, determined using multiwavelength observations of polarized radio emission in the microwave range at the radiotelescope RATAN-600. The observations were compared with the current-free magnetic field extrapolation of the photospheric field. It is shown that the measured magnetic field is always larger than the reconstructed field at the same height. The slopes of the tubes obtained by this method corresponds to the slopes obtained for the reconstructed field, although the degree of the slope differ significantly. The measured magnetic field structure is probably more complicated than the structure obtained by the reconstruction. Comparison of our measurements with previous measurements of radio astronomical heights at fixed frequencies showed good match.

Jupiter’s Decametric and Hectometric Radio Emissions Observed by Cassini RPWS and Voyager PRA. Planetary Radio Emissions| PLANETARY RADIO EMISSIONS VII 7|

The relationship between Jupiter’s decametric (DAM) and hectometric (HOM) radio emissions is important to help understand the emission mechanism that both of them have in common, but it has remained an elusive enigma. We have investigated Jovian DAM and HOM emissions observed by the Cassini, Voyager 1 and Voyager 2 spacecraft. We made a statistical comparison of Cassini and combined Voyager 1 and 2 data for occurrence probability histograms in Central Meridian Longitude (CML) and in Io phase from 2 to 16 MHz, and a statistical analysis of Jovian HOM polarization plotted as a function of Jovian magnetic latitude and frequency below 3 MHz based on only the Cassini data. We found that (1) the position of Source B shows shifts in longitude from 10 to 16 MHz as seen in both Cassini and combined Voyager 1 and 2 data, (2) the effect of Io can be seen down to 4 MHz, (3) the occurrence probability of HOM emissions are separated into right- and lefthand polarization senses, and (4) attenuation bands make a large contribution to intensify the HOM emissions around the attenuated regions.

In this paper we review the response of these emissions to dynamics in Saturn’s magnetosphere, driven by factors internal and external to the system. We begin by reviewing solar wind data upstream of Saturn and discuss the link between solar wind compressions and dynamics in Saturn’s magnetosphere, evidenced by intensifications and occasional phase changes in the SKR emission. We then review the link between magnetotail reconnection and planetary radio emissions. We begin in the well-sampled magnetotail of Earth and then move to Saturn where exploration of the nightside magnetosphere has revealed evidence of plasmoid-like magnetic structures and other phenomena indicative of the kronian equivalent of terrestrial substorms. In general, there is a good correlation between the timing of reconnection events and enhancements in the SKR emission, coupled with extension of the emission to lower frequencies. We interpret this as growth of the radio source region to higher altitudes along the field lines, stimulated by increased precipitation of energetic electrons into the auroral zones following reconnection. We also comment on the observation that the majority of reconnection events occur at SKR phases where the SKR power would be expected to be rising with time, indicating that reconnection is most likely to occur at a preferred phase. We conclude with a summary of the current knowledge of the link between Saturn’s magnetospheric dynamics and SKR emissions, and list a number of open questions to be addressed in the future.

Mathematics, Physics and Space Research
Massive extrasolar planets are expected to emit, in analogy with Jupiter and Saturn, detectable radio emission at low frequencies. We have carried out a series of observations of known extrasolar planetary systems at 150 MHz with the Giant Meterwave Radio Telescope (GMRT) in both interferometric and phased array modes. As low frequency observations are plagued with RFI, we have focused on observing strategies and analysis techniques to minimize, identify and remove RFI effects from dynamic spectra. Pulsar data obtained during each observing campaign have been used to validate novel detection algorithms for non-thermal events. In this report we will summarize our observing campaigns and present our detection algorithms and results. We will also briefly discuss prospects for similar searches with instruments that are now coming online as well as prospects with future instruments such as the SKA.

Unusual Spectra of Polarized Radio Emission of Active Regions on the Sun. Planetary Radio Emissions| PLANETARY RADIO EMISSIONS VII 7|
Kaltman, T. I.
Bogod, V. M.
Yasnov, V.
Mathematics, Physics and Space Research
Unusual spectra with a significant decrease in circularly polarised emissions (Stokes parameter V ) in the middle part of the microwave range (6 - 12 GHz), sometimes with a change of the polarization sign, were revealed by observations with the radio telescope RATAN-600 in the microwave range 2 - 16 GHz. Such features can be explained by the presence of a hot region in the solar corona. The magnetic field strength of the hot region and the product of the relative gradient of the magnetic field on its thickness are defined.

Morphology of the Jupiter Io-D decametric radio source. Planetary Radio Emissions|PLANETARY RADIO EMISSIONS VIII 8|
Mathematics, Physics and Space Research
Observations of Jupiter’s Io-D decametric radio emissions have been made with the Long Wavelength Array Station 1 (LWA1) from 2012–2015. The LWA1 data show new characteristics in dynamic spectra of Jupiter Io-D emission, including a double–envelope structure filled with spectral arc features, persistent narrowband events, and ubiquitous modulation lanes and S-bursts. We observe an Io-D peak frequency of 26.5 MHz implying a lower limit of 9.3 Gauss for the southern hemisphere magnetic field magnitude. We estimate a Jovian longitude of 235° for the center location of the Io-D peak frequency source. Many S-burst drift rates were measured as a function of frequency and were found to be consistent with other Iorelated sources. The Io-D source occurrence boundaries require new limits: CML = 0° − 287° and ΦIo = 50° − 135°.

Properties of groups of solar S-bursts in the decameter band. Planetary Radio Emissions|PLANETARY RADIO EMISSIONS VIII 8|
Mathematics, Physics and Space Research
On 9 July 2013 from 5:30 UT till 13:28 UT more than 1000 S-bursts were recorded by the Ukrainian radio telescope UTR-2 operated in the frequency band 9–32 MHz. All S-bursts were low intensity events with an average flux of about 10 s.f.u. and a minimum flux as low as 0.2 s.f.u. which made their detection with small instruments practically impossible. New methods of observations allowed to retrieve the weakest S-bursts with fluxes comparable to the background level. The durations and frequency drift rates of these bursts as well as the dependencies of these parameters on frequency were found. The obtained results complement the analysis by Morosan et al. [2015] with data at lowest frequencies accessible for ground-based observations.

We present an overview of the recent results in solar observations obtained at decameter radio waves using the radio telescope UTR-2. Due to up-to-date recording facilities some newly discovered phenomena in the frequency range 10 - 30 MHz are given: fast type III bursts, fine time structures in normal type III bursts, solar S-bursts, type IV bursts with zebra-like fine structures, third harmonic in type II bursts and bursts in absorption of different time scale. Newly discovered properties of well known bursts such as type III bursts, type IIIb bursts, type II bursts and drift pairs were obtained too.

Properties of Powerful Solar Type III Bursts in the Frequency Range of 10-30 MHz. Planetary Radio Emissions| PLANETARY RADIO EMISSIONS VII 7|

We report on the observation of powerful (fluxes are larger than 10-19 W/m2Hz) solar type III bursts at frequencies of 10-30 MHz using the radio telescope UTR - 2. The properties of powerful type III bursts observed in July 2002 (163 bursts) and August 2002 (231 bursts) were analysed. It was determined that the majority of these bursts were observed on days when an active region was located near the central meridian or at longitudes of 400 - 600 to the east or west of the central meridian. All of these bursts drift from high frequency to low with frequency drift rates of 1-2.5 MHz/s in most cases. We note that the frequency drift rate of these bursts increases linearly with frequency for all days of observation. This indicates that the solar corona above active regions shows an exponential density decrease with distance. The typical duration of the powerful type III bursts changes from 6 to 12 s. The instantaneous frequency widths of these bursts do not depend on the day of observation. There is a linear dependence between the average frequency width and frequency. The implication of these observations are discussed in the frame of the plasma model for the type III bursts generation.

Jovian Radio Emissions Modeling and their Future Investigation with EJSM (invited; abstract). Planetary Radio Emissions| PLANETARY RADIO EMISSIONS VII 7|
Cecconi, B.
Zarka, P.
Hess, S.
Mathematics, Physics and Space Research
Dynamic spectra of planetary radio emissions depend on physical and geometrical conditions: emission process; energy of emitting electrons; angle between the source magnetic field and the wave direction, which varies with frequency; location of the observer... Their modeling is an intrinsically 3-dimensional problem for which a code has been developed: SERPE / ExPRES (Simulateur d’´Emissions Radio Plan´etaires et Exoplan´etaires / Exoplanetary and Planetary Radio Emissions Simulator). This tool has been successfully applied to the modeling of arc-shaped radio emissions generated by the Io-Jupiter electro-dynamic interaction, as well as of Saturn’s Kilometric Radiation dynamic spectra. It allowed us to determine the energy of the emitting electrons, to identify the important of the oblique mode in the rarefied auroral plasmas of Jupiter and Saturn and to clarify the link between the Io-Jupiter radio emissions and of the UV spot at the magnetic footprint of Io. In light of these results, we will briefly review the characteristics of radio emissions related to Jupiter’s aurorae and to satellite-Jupiter interactions. The EJSM (Europa Jupiter System Mission) mission is a unique opportunity to study the Jovian magnetosphere (from the close environment of Galilean satellites and their coupling with the Jovian magnetic field, to the auroral regions of Jupiter). It should carry the first goniopolarimetric radio receiver in Jovian orbit. We will illustrate with Cassini results the scientific enhancement of radio astronomy science brought by such capabilities that will not be available to any other mission around Jupiter. We will show how our present knowledge of Jupiter’s decameter radio emissions may allow us to optimize the scheduling of low-frequency radar observations. Finally, we will discuss the unique opportunities that would be offered by multi-spacecraft magnetospheric observations in the Jovian system.

Mathematics, Physics and Space Research
We study the large scale structures of the electron core in the inner magnetosphere of Saturn (from the G-ring to Rhea orbit - i.e. 2.8 to 9 Rs). This study is deduced from the power spectra measurements acquired with the Cassini/RPWS electric dipole around the local plasma frequency (quasi-thermal noise spectroscopy), from July 2004 (SOI) to February 2010. We have especially investigated the radial diffusion and latitudinal confinement of the plasma torus towards Enceladus and Dione. We also discuss the longitudinal variations of the electron parameters using the recent SLS3 system. We will finally touch about the dust detection by using the RF power spectra measured on the monopole antenna and the possible effect of the dust on the observed electron parameters.

AKR Diurnal, Semi-Diurnal and Shorter Term Modulations Disentangled by Cassini/RPWS Observations (abstract). Planetary Radio Emissions| PLANETARY RADIO EMISSIONS VII 7|
Lamy, L.
Zarka, P.
Prangé, R.
Mathematics, Physics and Space Research
During the flyby of the Earth by Cassini in 1999, the Radio and Plasma Wave Science (RPWS) instrument recorded one month of quasi-continuous observations of Auroral Kilometric Radiation (AKR). Analyzing the Stokes parameters of incoming radio waves, we found AKR to be 100% circular left-handed (LH) or right-handed (RHW). We analyzed separately the northern - RH - emission, from the southern - LH - one with respect to the magnetic equator. AKR power variations reveal (i) a log-normal distribution at time scales of minutes, (ii) bursts of emission at time scales of a few hours, and (iii) a clear modulation at 24 hours, with a weaker modulation at 12 hours (especially visible for LH emissions). The prominent 24 h modulation is found to modulate LH and RH AKR in phase opposition. This is interpreted as being due to visibility effects related to the precession of the terrestrial magnetic dipole, making Cassini oscillate relative to the average AKR beaming pattern from each hemisphere. We accordingly quantified the AKR beaming vs explored latitudes. On time scales shorter than a few hours, LH and RH emissions are found to be correlated. This is attributed to the actual conjugacy of the corresponding sources, simultaneously turned on by substorm occurrence. The geometrical anti-correlation (at 24 h) dominates close to Earth, while the short term correlation (substorms) dominates far from Earth, where the detection threshold makes the visibility less important than the occurrence of substorms. Finally, the 12 h modulation is detected when it is not masked by strong visibility effects, i.e. for the LH emission which is observed mostly near the magnetic equator along the path of Cassini. A 12 h modulation being also observed in some geomagnetic indices, we suggest that a physical process (e.g. semi-diurnal variable efficiency of the reconnection between interplanetary and geomagnetic fields, or magnetotail oscillations) may be responsible of the observed AKR 12 h modulation.

The discovery of more than 500 exoplanets during the past 15 years has enabled us to characterize the upper atmosphere structure of some exosolar gas giants and to compare observational and modelling results to the known planets in the Solar System. It is of great interest to understand if these exosolar “Hot Jupiters” share similar physical processes compared to the giant planets (Jupiter and Saturn) in the Solar System with regard to their magnetic dynamos and the corresponding expected magnetic field strengths. In this work we discuss how observations of stellar Lyman-a absorption by so-called Energetic Neutral Atoms (ENAs) around transiting exoplanets together with theoretical modelling efforts can be used as a tool for estimating magnetic obstacle sizes and the corresponding magnetic field strength. For demonstrating this method we model the production of stellar wind related planetary hydrogen and ENA populations around the exosolar gas giant HD 209458b and show how a detailed analysis of attenuation spectra obtained during transits can be used for the estimation of the planet’s magnetic obstacle size and hence its dynamo field strength. Our study indicates that the magnetic field strength of HD 209458b which is able to balance the stellar wind plasma flow by a magnetic obstacle around the planet which can explain the observed Lyman-a line profiles observed before and during the transits by HST corresponds to a magnetic dipole moment which is ~40 % of Jupiters value.

The european radio telescope LOFAR is in its commissioning phase. It is a huge interferometer operating at low frequencies (30 to 240 MHz), composed of ~50 phased arrays (or stations) which are themselves gathering 864 to 1632 antennas. ~40 stations are located in the Netherlands along with the central correlator, and the other stations are spread over surrounding countries.In France, one of these arrays (1632 elements and their 96 associated receptors) has been built at the Nançay radioastronomy observatory. LOFAR will operate as an interferometer (for spectro-imagery) and as a global coherent phased array (for dynamic spectrometry).Its planetary objectives, that will be addressed by the Planets Working Group of LOFAR’s ”Transients” Key Science Project, include the fast imaging of the Jovian magnetosphere through its auroral radio emissions, and the detection and study of lightning on every planet of our solar system. Jupiter is the most intense low-frequency point source in the sky (> 106Jy), allowing extensive commissioning tests, which will be briefly described (including early interferometric observations between Nan¸cay and the Netherlands). In the case of Saturn’s lightning, the large instantaneous bandwidth (up to 48 MHz) and the high time resolution of LOFAR (down to 5 µs per spectrum) allow us to measure the discharge spectrum and energy(see Grießmeier et al., this issue, 145-154). Moreover, one of the major objectives of LOFAR is the detection and study of exoplanetary radio emissions, which will be an unique source of information about the magnetic field, rotation and inclination of these objects, and about planet-star plasma interactions in general. In our solar system, each planetary magnetosphere has common as well as singular characteristics, which make it differ from the others. Radio detection of exoplanetary magnetospheres with allow us to explore parameter space of magnetospheric physics and enhance comparative studies (see Zarka, this issue, 287-301).

Is a Rikitake Dynamo in Saturn’s Interior at the Origin of the Variability of the Radio Rotation Periods?. Planetary Radio Emissions| PLANETARY RADIO EMISSIONS VII 7|
Galopeau, P. H. M.
Mathematics, Physics and Space Research
Recent observations performed by the radio and plasma wave science (RPWS) experiment on board the Cassini spacecraft have revealed the presence of two distinct and variable spin modulation periods (10.6 hours and 10.8 hours) in Saturn’s radio emissions emanating from the northern and southern hemispheres respectively. The main time modulation of planetary radio emissions has always been attributed to the effect on the inner magnetosphere of the internal magnetic field which rigidly rotates with the deep interior of the planet. The magnetospheric plasma is supposed to be frozen in this magnetic field so that a north/south asymmetry in the radio modulation period should never be observed. However Saturn’s magnetic field is very particular since its dipolar moment is nearly aligned with the rotation axis of the planet. Such an alignment could bring out some phenomena in the internal structure which are masked in the case of other magnetized planets the magnetic dipole of which is significantly tilted. The existence of two separated and slowly varying periods in the saturnian magnetic field could be the signature of a dynamo the dynamics of which is governed by a Rikitake system.

The Cassini spacecraft flew very near a source region of Saturn kilometric radiation (SKR) on day 073 of 2008. This is the second known encounter with a source region at high latitude. The radio and plasma wave instrument, RPWS, observed intense SKR in the extraordinary (X) mode. The electron low-energy spectrometer (ELS) obtained a phase space distribution of sufficient energy and pitch angle resolution to allow growth rate calculations for the observed wave emissions. There is evidence of a shell or horseshoe electron plasma distribution that is unstable to the growth of SKR via the cyclotron maser instability. We present results of these calculations for comparison with a previously reported source region encounter.

A procedure to combine radio data from the Low Frequency Array (LOFAR) [ASTRON, 2010] and the Giant Ukrainian Radio Telescope (GURT) [Konovalenko, et al., 2009] is described. LOFAR is being deployed with 36 stations in the Netherlands and 8 international stations in the neighbouring countries where the central 18 stations close to Exloo in the Netherlands form a core. Data from the Low Band Antennas in the frequency range 10–80 MHz (10–30 MHz with reduced sensitivity) of the LOFAR station in Bornim close to Potsdam, Germany, 1,500 km from GURT will be used. GURT is being built at the site of the UTR-2 radio telescope close to Charkov, Ukraine. It covers the range 10–70 MHz and the final effective area of GURT will be comparable to the LOFAR core. The GURT data will be converted into narrow bands of the same bandwidth and the same centre frequencies as the LOFAR data. Comparisons of the dynamic spectra from the two stations will be made and the data from the stations can be combined to make use of the long baseline. Scientific focus will be on solar physics within the LOFAR Solar physics and space weather key science project, but the long baseline also allows for investigations of radio sources which require a higher angular resolution than the sun.

Simulating Jupiter-satellite decametric emissions with ExPRES: A parametric study. Planetary Radio Emissions|PLANETARY RADIO EMISSIONS VIII 8|
Mathematics, Physics and Space Research
The high latitude radio emissions produced by the Cyclotron Maser Instability (CMI) in Jupiter’s magnetosphere extend from a few kHz to 40 MHz. Part of the decametric emission is of auroral origin, and part is driven by the moons Io, Europa and Ganymede. After summarizing the method used to identify Jupiter– satellite radio emissions, which consists in comparing space- and ground-based radio observations to ExPRES simulations of CMI–driven emissions in the time–frequency plane, we present a parametric study of the free parameters required by the ExPRES code (electron distribution function and resonant energy, magnetic field model, lead angle, and altitude of the ionospheric cut-off) in order to assess the accuracy of our simulations in the Io–Jupiter case. We find that Io–DAM arcs are fairly modeled by loss–cone driven CMI with electrons of 1–10 keV energy, using the ISaAC, VIPAL, or VIP4 magnetic field model and a simple sinusoidal lead angle model. The altitude of the ionospheric cut-off has a marginal impact on the simulations. We discuss the impact of our results on the identification of Europa–DAM and Ganymede–DAM emissions.

Is the AKR Cyclotron Maser Instability a self-organized criticality system?. Planetary Radio Emissions|PLANETARY RADIO EMISSIONS VIII 8|
Mathematics, Physics and Space Research
Data gathered by the POLRAD swept frequency radiospectrograph (Interball–2 mission) have been used for a preliminary analysis of a number of short bursts of the Auroral Kilometric Radiation (AKR) as a function of their intensity. The AKR intensity samples consisted of data snapshots integrated over 6 ms time periods. The histograms based on 53 data sets, containing up to several thousand samples, exhibit a power–law fall for higher intensities, characteristic for Self–Organized Criticality (SOC). The scaling parameter α varies for most cases between 2 and 3 with the dominant value 2.5, and an error of the order of 0.1. The SOC approach has already been used for an interpretation of some magnetospheric processes, but never for AKR.

AKR Sources Positions - Interball 2 vs CLUSTER Observations. Planetary Radio Emissions| PLANETARY RADIO EMISSIONS VII 7|
Hanasz, J.
Panchenko, M.
Schreiber, R.
Mathematics, Physics and Space Research
Interball-2 (Auroral Probe) Polrad triaxial spectropolarimeter was used to determine positions of AKR source footprints on the auroral oval. Our findings are consistent with AKR beams narrowly confined to a plane tangent to the source magnetic latitude circle and containing the local magnetic field vector, in agreement with Mutel et al. [2008]. Our approach is based on dynamic spectra data analysis on much longer time scale of two-minute moving averages, as compared to AKR microbursts tens of milliseconds long analyzed by Mutel et al. We show detailed AKR visibility maps for a given position of the spacecraft - that allow determination of both the azimuth and elevation of the AKR beam in question for every measured AKR source position. For long data runs of the order of one hour we see apparent motion of the AKR sources as measured by Polrad, following spacecraft motion along the orbit in such a way, that the spacecraft remains within the radiation beam obeying geometric constraints reported by Mutel et al.

Currents on the conducting surfaces of the spacecraft hull, induced by electric fields of radio waves, strongly influence the reception properties of spacecraft antenna systems. This influence is visualized by the so-called ”effective antenna length” (heff ), representing the electric antenna, which differs from the physical antenna rod. Knowledge on these effective antenna vectors can be yielded by several different methods: (1) Experimental rheometry, (2) Numerical computer simulations, (3) In-flight calibration, and (4) Experimental anechoic chamber measurements. The paper addresses these methods and shows in the case of preliminary design studies of Solar Orbiter spacecraft the possibilities of numerical computer simulations, in particular the change of heff by design variations. The combined use of the above mentioned methods enables the determination of heff over a wide frequency range, the correct information on wave polarisation, and in specific cases helps to improve the performance of direction finding. So the calibration results may also be used to re-evaluate structure and position of antennas (and even positions of instruments) on board a spacecraft.

On Kinetic Approach to Modeling of Sources of Electromagnetic Radiation Located in Planet/Stellar Electroctromagnetic Structures (abstract). Planetary Radio Emissions| PLANETARY RADIO EMISSIONS VII 7|
Gubchenko, V. M.
Mathematics, Physics and Space Research
Electromagnetic radiation from stars and planets appeared at the different wavebands. Radiation is provided by accelerated particles originated from plasma electromagnetic structures which are named the particle sources. Structures are selfconsistent with inductive e.m. fields and collisionless hot plasma electrodynamics including plasma part formed by accelerated particles. Here quasifree acceleration by inductive eddy e.m. field takes place. The sources are related with the diffusion regions (DR) of plasma where we get weak particle magnetization and where plasma kinetic process of magnetic reconnection takes place. In the DR electric current can be parted on the diamagnetic and on the resistive components. Current components in DR source are in ratio G and the components are related with non accelerated (diamagnetic) particles and accelerated (resistive) particles. Parameter G is calculated via momentum and energy anisotropy parameters depending on shape of the particle velocity distribution function (VDF). Parameter G can be positive and negative; G defines resistive, diamagnetic and quasi-current free dynamics of the DR as a source of accelerated particles. The G is the e.m. analog of the acoustic Mach number M. Plasma DR structures are described by anomalous skin-scale and diamagnetic skin scale. We introduced criteria on value of plasma beta and on value of anisotropy parameters to get the DR plasma structures realization.

Variability of Southern and Northern SKR Periodicities. Planetary Radio Emissions| PLANETARY RADIO EMISSIONS VII 7|
Lamy, L.
Mathematics, Physics and Space Research
Among the persistent questions raised by the existence of a rotational modulation of the Saturn Kilometric Radiation (SKR), the origin of the variability of the 10.8 hours SKR period at a 1% level over weeks to years remains intriguing. While its short-term fluctuations (20-30 days) have been related to the variations of the solar wind speed, its long-term fluctuations (months to years) were proposed to be triggered by Enceladus mass-loading and/or seasonal variations. This situation has become even more complicated since the recent identification of two separated periods at 10.8h and 10.6h, each varying with time, corresponding to SKR sources located in the southern (S) and the northern (N) hemispheres, respectively. Here, six years of Cassini continuous radio measurements are investigated, from 2004 (preequinox) to the end of 2010 (post-equinox). From S and N SKR, radio periods and phase systems are derived separately for each hemisphere and fluctuations of radio periods are investigated at time scales of years to a few months. Then, the S phase is used to demonstrate that the S SKR rotational modulation is consistent with an intrinsically rotating phenomenon, in contrast with the early Voyager picture.

Recent Cluster WBD observations in the Earth’s auroral acceleration region have detected trapped Z mode auroral kilometric radiation while the spacecraft were entering a deep density cavity. The Z mode has a clear cutoff at the local upper hybrid resonance frequency, while RX mode radiation is detected above the RX mode cutoff frequency. The small gap between the upper hybrid resonance and the RX mode cutoff frequencies is proportional to the local electron density as expected from cold plasma theory. The width of the observed gap provides a new sensitive measure of the ambient electron density. In addition, the relative intensities of RX and Z mode radiation provide a sensitive probe of the plasma ß = ?pe/Oce at the source since the growth rates, although identical in form, have different ranges of allowed resonant radii which depend on ß. In particular, the RX mode growth is favored for low ß, while the Z mode is favored at higher ß. The observed mode intensities and ß’s appear to be consistent with this model, and favor generation of Z mode at the source over models in which Z mode is generated by mode-conversion at cavity boundaries. These are the first multi-point direct measurements of mode-specific AKR propagation in the auroral acceleration region of any planet.

The Nançay radio astronomy observatory and associated laboratories are developing the concept of a “Super Station” for extending the LOFAR station now installed and operational in Nan¸cay. The LOFAR Super Station (LSS) will increase the number of high sensitivity long baselines, provide short baselines and an alternate core, and be a large standalone instrument. It will operate in the low frequency band of LOFAR (30–80 MHz) and extend this range to lower frequencies. Three key developments for the LSS are described here: (i) the design of a specific antenna, and the distribution of such antennas (ii) at small-scale (analog-phased mini array) and (iii) at large-scale (the whole LSS).

Analyzing a database of 26 years of observations of Jupiter from the Nan¸cay Decameter Array, we study the occurrence of Io–independent emissions as a function of the orbital phase of the other Galilean satellites and Amalthea. We identify unambiguously the emissions induced by Ganymede and characterize their intervals of occurrence in CML and Ganymede phase and longitude. We also find hints of emissions induced by Europa and, surprisingly, by Amalthea. The signature of Callisto–induced emissions is more tenuous.

Auroral electron energy estimation using the H/H2 brightness ratio applied to Jupiter. Planetary Radio Emissions|PLANETARY RADIO EMISSIONS VIII 8|
Mathematics, Physics and Space Research
The measurement of the H/H2 brightness ratio of giant planets’ far-ultraviolet (FUV) aurora is a proxy for precipitating soft (a few 10s keV) electrons. We investigate the relevance of this H/H2 indicator with the Jupiter auroral observations obtained by the Hubble Space Telescope. The H/H2 ratio does not show any clear relationship with the FUV color ratio which is sensitive to more energetic electrons. Compared to the same analysis applied for Saturn’s aurora, the relationship for Jupiter mainly shows decreasing flux with increasing energy without acceleration features.

The lightning activity in Saturn’s atmosphere has been monitored by Cassini for more than six years. The continuous observations of the radio signatures called SEDs (Saturn Electrostatic Discharges) combine favorably with imaging observations of related cloud features as well as direct observations of flash–illuminated cloud tops. The Cassini RPWS (Radio and Plasma Wave Science) instrument and ISS (Imaging Science Subsystem) in orbit around Saturn also received ground–based support: The intense SED radio waves were also detected by the giant UTR–2 radio telescope, and committed amateurs observed SED–related white spots with their backyard optical telescopes. Furthermore, the Cassini VIMS (Visual and Infrared Mapping Spectrometer) and CIRS (Composite Infrared Spectrometer) instruments have provided some information on chemical constituents possibly created by the lightning discharges and transported upward to Saturn’s upper atmosphere by vertical convection. In this paper we summarize the main results on Saturn lightning provided by this multi–instrumental approach and compare Saturn lightning to lightning on Jupiter and Earth.

The new mechanism for the formation of a fine structure in the dynamic spectra of the Jovian decametric radio emission is proposed. The main attention is paid to the formation of narrow-band (NB) emission and quasiperiodic trains of S-bursts. Our model is based on the effects of occurrence of the amplitude-frequency modulation and extension of the frequency spectrum of a signal during propagation of the radiation in a medium with time-varied parameters. It is shown that non-stationary disturbances of the planetary magnetic field and strong frequency dispersion of the plasma at frequencies close to the cutoff frequency of the extraordinary wave in the Jovian ionosphere can play a crucial role in the formation of NB emission and quasiperiodic trains of S-bursts. As a result of the numerical experiments, it was concluded that the amplitude-frequency characteristics of an initially continuous signal can drastically vary as functions of the form of the magnetic-field disturbance in the Jovian ionosphere. Structures similar to those observed in the real experiments, ranging from NB emission and quasiperiodic trains of S-bursts to more complex structures, arise in the dynamic spectrum.

Can the Relativistic Maser Mechanism Cause the Strong Emissions Registered by Cluster and Demeter Satellites in the Polar Cusp? (abstract). Planetary Radio Emissions| PLANETARY RADIO EMISSIONS VII 7|

The emissions with extremely high intensity around electron cyclotron frequency have been sometimes registered by satellite Magion 4 - companion of Interball 1. These waves correlate with strong fluxes of high energetic electrons often observed within the polar cusp by Interball 1 and Magion 4 as well as by Polar satellites. Multipoint measurements done by Cluster satellites give new insight of these emissions. Taking into account the plasma and magnetic field parameters in the polar cusp as well as geometry of the waves propagation, one has found that one type of these emissions can be generated by so called ”fan instability” (FI) , but as a source of the emissions around electron cyclotron frequency the ’horse shoe’ instability has been also discussed. Beam instability and interaction of Langmuir waves with energetic electrons give the broad band emissions around plasma frequency, which can be discussed as Langmuir turbulence (LT). Kilometric radiation (KR) typical for auroral zone is observed in the vicinity of the cusp’s boundary and is associated with fluxes of electrons with energy up to 100keV. The wave measurements done by DEMETER satellite in the polar cusp at the ionospheric level shown similar effects to registered by Interball and Cluster in the outer cusp. The presence of the energetic electrons during the bursts of the plasma waves can suggest another mechanism - relativistic maser instability. The discussion of the possibility of this mechanism in relation to the presented observation will be given in our paper.

Saturn narrowband (NB) radio emissions are detected between 3 and 70 kHz, with occurrence probability and wave intensity peaking around 5 kHz and 20 kHz. The emissions usually occur periodically for several days after intensification of Saturn kilometric radiation (SKR). Originally detected by the Voyagers, the extended duration of the Cassini mission and the improved capabilities of the Radio and Plasma Wave Science (RPWS) instrument have significantly advanced our knowledge about them. For example, RPWS measurements of the magnetic component have validated the electromagnetic nature of Saturn NB emissions. Evidences show that the 20 kHz NB emissions are generated by mode conversion of electrostatic upper hybrid waves on the boundary of the plasma torus, whereas direction–finding results point to a source in the auroral zone for the 5 kHz component. Similar to SKR, the 5 kHz NB emissions have a clock–like modulation and display two distinct modulation periods identical to the northern and southern hemisphere periods of SKR. Polarization measurements confirm that most NB emissions are propagating in the L–O mode, with the exception of second harmonic NB emissions. At high latitudes closer to the planet, RPWS detected right hand polarized Z–mode NB emissions below the local electron cyclotron frequency (fce), which are believed to be the source of the L–O mode NB emissions detected above the local fce. Although the energy source for the generation of the Z–mode waves is still unclear, linear growth rate calculations indicate that the observed plasma distributions are unstable to the growth of electrostatic cyclotron harmonic emission. Alternatively, electromagnetic Z–mode might be directly generated by the cyclotron maser instability. The source Z–mode waves, upon reflection, propagate to the opposite hemisphere before escaping through mode conversion, which could explain the fact that both rotational modulation periods of NB emissions are observable in each hemisphere.

101 Things That You Might Have Wondered About Space Plasma Wave Research But Were Afraid To Ask!. Planetary Radio Emissions| PLANETARY RADIO EMISSIONS VII 7|
Anderson, R. R.
Mathematics, Physics and Space Research
Whistlers are electromagnetic waves generated by lightning discharges traveling through the ionosphere where the dispersion relations show that the higher frequency emissions travel faster than the low frequency emissions. Satellite analog wave receivers allowed the Very Low Frequency (VLF) (less than 30 kHz) waves to be transmitted to the ground by modulating a Very High Frequency carrier. Spectrograms of some whistlers showed emissions with rising components beginning below the ion cyclotron frequencies and later referred to as proton, helium, or oxygen ion whistlers. Analyses of the crossover frequency, the asymptotic frequency, and the dampening rate yielded relative mass density, magnetic field magnitude, and electron temperature. The INJUN V satellite instrumentation was able to determine the propagation direction up or down the geomagnetic field line. Whistlers verified the calibrations. VLF saucers centered on regions of intense energetic electron precipitation were shown to be upgoing from the auroral region. The upper frequency limits of the filter banks on these satellites were 35 kHz and 100 kHz. Subsequent satellite receivers progressively increased the upper frequency limits of both the digital filter banks and analog wideband receivers. The dominant auroral emission was auroral kilometric radiation (AKR) whose intensity peaks around 250 kHz. AKR observations from the UC Berkeley FAST spacecraft show that it is primarily generated slightly above the local relativistic electron cyclotron frequency. AKR frequency limits extend from below 15 kHz to at least 800 kHz showing that it is generated over a large spatial range of several Earth radii. High resolution wave forms show tones and emissions embedded in the AKR data indicating significant ion influences. Observations of Type II and Type III solar radio bursts produced by coronal mass emissions and solar flares provide details of the interplanetary medium density structure.

We present recent studies on large-scale solar coronal waves (so-called ”EIT waves”) obtained with the EUVI instruments onboard the twin STEREO spacecraft. EUVI has several advantages for coronal wave studies: a) high cadence full-disk imaging, which allows us to catch the wave evolution and kinematics, b) a large field-of-view, which allows simultaneous observations of the erupting CME, and c) observations from two vantage points, which enable us to get insight into the threedimensional structure of the wave. The present understanding is basically split into different groups of ”wave” versus ”non-wave” interpretations of the physical process behind the phenomenon, as well as ”flare” versus ”CME” for the driving agent. We will present the first observations of the full three-dimensional wave dome in the event of January 17, 2010. The study of the perturbation characteristics and the associated high-frequency radio type II bursts provide evidence for a weakly shocked fast-mode wave as the underlying physical process.

Application of a new method for calculation of low-frequency wave vectors. Planetary Radio Emissions|PLANETARY RADIO EMISSIONS VIII 8|
Mathematics, Physics and Space Research
The problem of resolving spatial and temporal properties of waves, so-called “space–time ambiguity”, is a longstanding issue of single–spacecraft measurements. The general case can be insoluble, but in special cases in which certain assumptions hold, such as when each frequency corresponds to a single wave vector, the ambiguity can be resolved. Recently a method has been proposed to obtain wave vectors from single–spacecraft measurements of Alfvén wave–modulated magnetic fields and currents [Bellan, 2016], through application of the Wiener–Khinchin theorem to cross-correlation of the current density J and magnetic field B, and to the autocorrelation of B. We apply this method to spacecraft data, obtained by culling, from a large database of inertial Alfvén waves observed by the FAST satellite, two case study intervals during which extraordinarily large modulated currents were measured by the FAST particle detectors in burst mode. Results of this analysis for at least one of the two case studies appear consistent with known properties of ionospheric inertial Alfvén waves and pass error and consistency checks within the analysis method.

Jovian DAM “Arcs” and Auroral Context (abstract). Planetary Radio Emissions| PLANETARY RADIO EMISSIONS VII 7|
Lecacheux, A.
Mathematics, Physics and Space Research
We compare a large database of Jovian DAM ‘great arcs” events with the most recent compilation of Io footprint (IFP) properties obtained from HST images of Jupiter UV auroras. The radio data was built from the last 16 years of Jupiter radio monitoring by the Wind/WAVES space experiment and by the Decameter array in Nan¸cay, and contents more than 3500 individual events. The analysis of this huge statistics lead to the following conclusions: ”Great arcs” can be found on spectrograms of both Io and non-Io controlled emissions (in nearly equal proportion), showing that the arc phenomenon is not specific to the particular Io-Jupiter interaction scenario. In the case of Io-controlled events, the observed arc curvatures and senses of circular polarisation, show that most of the observed events originate from one or several of the four possible high latitude limbs (corresponding to the well known A,B,C and D ‘regions” in CML-Io phase diagram). In each region, a close relationship exists, at a given frequency, between observer’s direction and Io’s orbital position at the time of the event; already reported as “DE effect”, it means a surprisingly tight beaming constraint. By using reference IFP ovals (Bonfond et al., JGR 114, 2009) and magnetic field model (VIP4), the emission angle can be estimated for each individual events. When counting from magnetic field direction at the source location, the distribution of emission angles is broadly centred on ~ 70?, as previously determined by many authors. The distribution gets narrowed when the magnetic field gradient is rather used, suggesting that the observed emission angle depends primarily on propagation conditions near the source. Because of the limited accuracy of available magnetic field models, it is unclear whether our estimate of a ~ 10? “lead angle” between the active radio field line footprint and the auroral IFP, can be considered as statistically significant or not.

Veronig, A. M.

Magdalenic, J.

Muhr, N.
Mathematics, Physics and Space Research
We analyze evolution and kinematics of the fast, globally propagating Moreton wave of 2003 October 28 associated with the extreme X17.2 solar flare/CME event. This Moreton wave is distinct due to its azimuthal span of ~ 360 deg. Thus its characteristics are studied in different propagation directions, and compared with the associated phenomena: EIT wave, coronal dimmings, radio type II burst, fast halo CME, and flare. The sectoral analysis give mean velocity values in the range of v ~ 900 - 1000 kms-1; two sectors show wave deceleration. Analyzing the perturbation profiles indicates an amplitude growth followed by amplitude weakening and broadening, which is consistent with a disturbance first driven and then evolving into a freely propagating wave. We find two ”radiant points” for the Moreton wave fronts on opposite east-west edges of the source region, roughly co-spatial with the bipolar coronal dimming. Type II bursts are known as remote signatures of shocks propagating through solar atmosphere. Thus, the co-spatiality of the associated radio type II burst source and the first Moreton wave fronts indicate that the wave is an initially shocked fast-mode wave launched from an extended region. These findings indicate that the wave is initiated by the CME expanding flanks.

First observations near Jupiter by the Juno Waves investigation. Planetary Radio Emissions|PLANETARY RADIO EMISSIONS VIII 8|
Mathematics, Physics and Space Research
The Juno spacecraft successfully entered Jupiter orbit on 5 July 2016. One of Juno’s primary objectives is to explore Jupiter’s polar magnetosphere for the first time. An obvious major aspect of this exploration includes remote and in-situ observations of Jupiter’s auroras and the processes responsible for them. To this end, Juno carries a suite of particle, field, and remote sensing instruments. One of these instruments is a radio and plasma wave instrument called Waves, designed to detect one electric field component of waves in the frequency range of 50 Hz to 41 MHz and one magnetic field component of waves in the range of 50 Hz to 20 kHz. Juno’s first perijove pass with science observations occurred on 27 August 2016. This paper presents some of the first observations of the Juno Waves instrument made during that first perijove. Among radio emissions, kilometric, hectometric, and decametric emissions were observed. From a vantage point at high latitudes, many of Jupiter’s auroral radio emissions appear as V-shaped emissions in frequency–time space with vertices near the electron cyclotron frequency where the emissions intensify. In fact, we present observations suggesting Juno flew through or close to as many as five or six sources of auroral radio emissions during its first perijove. Waves made in-situ observations of plasma waves on auroral field lines such as whistler–mode hiss, a common feature of terrestrial auroral regions. We also discuss observations of dust at the equator and lightning whistlers observed over mid-latitudes.

Characteristics of type III radio bursts and solar S bursts. Planetary Radio Emissions|PLANETARY RADIO EMISSIONS VIII 8|
Mathematics, Physics and Space Research
The Sun is an active source of radio emission which is often associated with the acceleration of electrons arising from processes such as solar flares and coronal mass ejections (CMEs). At low radio frequencies (<100 MHz), numerous solar S bursts (where S stands for short) and storms of type III radio bursts have been observed, that are not directly relates to flares and CMEs. Here, we expand our understanding on the spectral characteristic of these two different types of radio bursts based on observations from the Low Frequency Array (LOFAR). On 9 July 2013, over 3000 solar S bursts accompanied by over 800 type III radio bursts were observed over a time period of ∼8 hours. The characteristics of type III radio bursts presented here are consistent with previous studies. S bursts are shown to be different compared to type III bursts: they show narrow bandwidths, short durations and drift rates of about 1/2 the drift rate of type III bursts. Both type III bursts and solar S bursts occur in a region in the corona where plasma emission is the dominant emission mechanism as determined by data constrained density and magnetic field models.

Localized Langmuir Eigenmodes and Solar Radio Bursts. Planetary Radio Emissions| PLANETARY RADIO EMISSIONS VII 7|
Ergun, R. E.
Hess, S. H.
Malaspina, ^D. M.
Mathematics, Physics and Space Research
Observed spatial- and frequency-domain signatures of the most intense solar wind Langmuir waves can be described as localized, discrete-frequency eigenmodes trapped in a parabolic density fluctuation. Electric field waveforms from spacecraft in the solar wind are compared with one- and three-dimensional solutions and, in many cases, can be represented by 1-3 of the lowest order eigenmodes. The spatial scale of eigenmode wave packets is on the order of tens of Langmuir wavelengths, allowing them to draw energy directly from the unstable electron distributions associated with a solar type III radio bursts and implying that Langmuir waves can grow in a strongly inhomogeneous medium. The currents generated by localized Langmuir eigenmodes emit coherent electromagnetic radiation as antennas at the fundamental and at twice the local plasma frequency. STEREO observations demonstrate that the currents required for eigenmode antenna radiation are present and have strengths within an order of magnitude of theoretical predictions. The eigenmode antenna radiation mechanism implies that, of all the Langmuir waves excited by an electron beam, relatively few localized antenna radiators may account for a majority of observed emission from an extended radio source. Finally, the possibility that turbulence may ultimately play a strong role in the generation of Langmuir waves and the radio emissions associated with solar type II and type III radio bursts is investigated.

Brightness temperature of decameter solar bursts with high-frequency cut-off. Planetary Radio Emissions|PLANETARY RADIO EMISSIONS VIII 8|
Mathematics, Physics and Space Research
In this paper we consider solar bursts with a high-frequency cut-off, simultaneously observed by several ground-based radio observatories located at significant distances from each other. The events were correlated with the emergence of a new group of solar spots on the far side of the Sun. The cut-off effect of the solar bursts was caused by the occultation of their radiating sources by the solar corona for observers on Earth. Based on the radio occultation of the low-frequency burst sources in the solar corona, we have estimated their angular sizes. This makes it possible to obtain the dynamic spectra of the solar bursts in terms of brightness temperature.

An Overview of the Time-Dependent Rotational Modulation of Saturnian Radio Emissions (invited; abstract). Planetary Radio Emissions| PLANETARY RADIO EMISSIONS VII 7|
Gurnett, D.A.
Mathematics, Physics and Space Research
The discovery of Saturn kilometric radiation (SKR) was made by the Voyager spacecraft over three decades ago. The Voyager observations showed that SKR had a well-defined clock-like amplitude modulation with a period of 10 hr 39 min 24±7 sec. Since then much has changed. In 2000 radio observations by the Ulysses spacecraft showed that the SKR modulation period varied by as much as several minutes on time scales of years. This long-term variability was subsequently confirmed by radio measurements from the Cassini spacecraft, which was put in orbit around Saturn on 1 July 2004. We now know that there are three basic types of Saturnian radio emissions: SKR at frequencies from about 50 to 1,200 kHz; narrowband (NB) emissions in two frequency ranges, near 5 kHz and near 20 kHz; and whistler-mode auroral hiss at frequencies from a few Hz to several kHz. All of these radio emissions display long-term variations in their modulation periods of up to one percent or more on time scales of years, with smaller variations on shorter time scales. For several years prior to Saturn’s recent equinox (August 2009) these radio emissions displayed two dominant periods of about 10.6 and 10.8 hours. The 10.6-hour period has been shown to be associated with SKR and auroral hiss originating from the northern auroral zone; and the 10.8-hour period has been associated with SKR and auroral hiss originating from the southern auroral zone. The narrowband emissions observed during this period have the same two periods as the SKR and auroral hiss, but do not have the corresponding north-south symmetry. As equinox approached the two periods converged and now appear to have crossed several months after equinox. A similar crossing of the two components may have occurred in the Ulysses measurements of SKR during the Saturn’s equinox fourteen years ago. Possible models for explaining these complex long term variations will be discussed.

Electron density measurements from the Cassini RPWS Langmuir Probe instrument have identified a sharply-defined region of low plasma densities in Saturn’s magnetosphere outside a dipole L-shell of ~15. Gradients in the density profiles define a boundary identified as the plasmapause [Gurnett et al., 2010] that separates the region of higher plasma density from the region of very low plasma density. During seven consecutive high-latitude passes in the northern hemisphere from September through December 2006, Cassini followed a series of trajectories that skimmed along high-latitude magnetic field lines for several days. The orientation of these trajectories made it possible for the RPWS to detect modulations in the high-latitude auroral hiss emissions at a 10.6 hour rotational modulation rate [Gurnett et al., 2009] and for the RPWS Langmuir Probe instrument to detect modulations in the electron density profiles that were anti-correlated with the hiss emissions [Gurnett et al., 2010]. The strong and periodic modulations in the density profiles indicate that Cassini is passing in and out of a plasma region of higher densities. One example during this seven-orbit time interval is shown in Figure 1. The periodic modulations in the density profile are shown in the bottom panel and are clearly anti-correlated with the periodic occurrence of intense auroral hiss emissions shown in the upper panel. The highest densities in this high-latitude region are 0.1 cm-3, two orders of magnitude greater than the lowest densities in this part of Saturn’s magnetosphere but well below the densities seen inside Saturn’s plasma disk [Morooka et al., 2009;Persoon et al., 2009].

Beaming Cone of Io-Controlled Jovian Decameter Radio Emission and Existence of Localized Active Longitude. Planetary Radio Emissions| PLANETARY RADIO EMISSIONS VII 7|
Boudjada, M. Y.
Galopeau, P. H. M.
Mathematics, Physics and Space Research
The occurrence probability of the Jovian decameter radio emissions depends on two essential parameters: the central meridian longitude (CML) and the orbital phase of the satellite Io. Four main zones of enhanced occurrence probability emerge from the CML-Io phase diagram: the so-called Io-controlled sources Io-A, Io-B, Io-C and Io-D. We study the compatibility of the location of these sources with the existence of a specific active longitude range, anchored in Jupiter’s magnetic field, and favoring the radio emissions. A theoretical model, based on the cyclotron maser instability (CMI), was proposed a few years ago in order to explain the existence of such active longitudes, assuming that the radiation was emitted at the local gyrofrequency in a hollow cone of constant angle, along a magnetic field line carried away by Io through its revolution around Jupiter. Unfortunately this model was not able to justify the dimension in longitude of all the Io-controlled sources, in particular those located in the Jovian southern hemisphere (Io-C and Io-D). We show that the azimuthal distribution of the four occurrence regions (Io-A, Io-B, Io-C and Io-D) around the gradient of the local magnetic field is not constant so that the emission cone (in each Jovian hemisphere) presents a significant flattening in the direction of the magnetic field vector. Introducing a beaming cone with an elliptical section makes the location and extension in longitude of the sources (in the CML-Io phase diagram) compatible with the existence of an active longitude. A theory of the CMI, acting in an inhomogeneous medium in which the magnetic field vector and the gradient of its modulus are not aligned, shall be required in order to justify the flattening of the emission cone.

We report on solar radio bursts observed by the RPWS experiment on board the Cassini spacecraft in the period from 1st January 2004 to 31st March 2010. In this time intervals of about six years a limited number of strong solar type III bursts, less than 300, has been recorded. This is mainly due to the solar activity which reaches its minimum in 2008–2009. In this study we consider type III solar bursts observed at frequencies lower than 1.2 MHz generated in the interplanetary medium. We analyse the solar bursts with the aim to estimate the Cassini local time (LT) occurrence rate, where the Kronian day has been divided into eight LT sectors. Our results are combined with the Cassini orbits where the LT and the distance to the planet are taken into consideration. We show that the type III burst occurrence rates depend on the solar activity, however the day side sector (midday to early afternoon) exhibits the lowest rate of occurrence.

Short antennas on a large spacecraft. Planetary Radio Emissions|PLANETARY RADIO EMISSIONS VIII 8|
Mathematics, Physics and Space Research
Short dipole or monopole radio antennas are defined as being small in length relative to the wavelength of the frequency of operation. The reception properties of short linear antennas can be described by the so-called effective length vector which is pointing along the direction of minimum gain in the toroidal radiation pattern. We deal here with such antennas, and additionally the word ”short” also means a small antenna with respect to a large spacecraft body. Using numerical computer simulations we calculate the reception properties of an antenna system consisting of three short monopoles positioned on a large spacecraft body in the frequency range of several hundred kHz. It turns out that such a configuration has the major disadvantage that the angular separation between its three effective length vectors is quite small, which would lead to large errors in polarization and direction–finding measurements. We will show ways how to overcome this problem by changing the configuration to an antenna triad consisting of three short dipoles mounted on a boom. The calculations were employed to find a good configuration of the radio antennas for ESA’s future JUICE (Jupiter Icy Moons Explorer) mission.

Direction Finding and Polarization Measurements of SKR (invited). Planetary Radio Emissions| PLANETARY RADIO EMISSIONS VII 7|
Lecacheux, A.
Mathematics, Physics and Space Research
The Saturnian Kilometric Radio emission (SKR), discovered and briefly observed by Voyager spacecraft in 1980-81, is now studied in depth by Cassini, which is still in orbit around Saturn, since mid 2004. Aboard Cassini, the main radio astronomy system (the HFR part of the RPWS instrument) is based on digital, real time, spectral correlation of several pass band filters, analyzing multiple wire antennas. This system allows, in principle, the full second order statistics of the analyzed signal to be retrieved, thus providing, compared to a simple antenna system, some extra information on the received radio waves: mainly about the spatial brightness distribution (leading to direction finding (DF) for a point source model) and the intrinsic polarisation of the measured radio source. While there is no doubt that SKR, like terrestrial and Jovian radio emissions, is powered via a cyclotron maser (CMI) originating from accelerated auroral particles, the exact scenario remains, at the moment, far from being understood: the complex modulation of the SKR at the planetary spin rate is perplexing; the fact that the apparent SKR polarization changes with observer’s latitude and contains a substantial amount of linear polarisation when observed from mid to high latitudes, is quite unexpected and likely the indication of a complex source structure and/or unusual propagation regime in Saturn’s high latitude regions.

S/NB-events of Jovian Decametric Emission. Planetary Radio Emissions| PLANETARY RADIO EMISSIONS VII 7|
Rucker, H. O.
Arkhypov, O. V.
Mathematics, Physics and Space Research
Narrow-band (NB) events in dynamic spectra and their relation with short (S-) bursts are an unresolved enigma of the Jovian decametric emission. This paper is focused on the S/NB-structure with timescales between 0.03 s and 0.3 s. We show that the main S/NB-phenomenology can be reduced to three main ingredients which are: the dispersion delay of the radio emission, the motion of emitting electrons in the parallel electric field of the standing Alfv´en wave, and the shadow effect.

Rotational modulation of Saturn Kilometric Radiation, narrrowband emission and auroral hiss. Planetary Radio Emissions|PLANETARY RADIO EMISSIONS VIII 8|
Mathematics, Physics and Space Research
Despite the axisymmetry of Saturn’s internal magnetic field, a variety of magnetospheric properties and radio emissions exhibit periodic modulations due to Saturn’s rotation. Previous studies have shown that Saturn kilometric radiation (SKR) and auroral hiss have two different modulation rates, one associated with each hemisphere, which also vary over the time scale of a Saturn year. The narrowband emissions exhibit dual periodicities in each hemisphere. We update the modulation analysis of Saturn’s radio emissions to the end of year 2016. It is shown that the northern SKR rotation slowed to around 800°/day in 2016, while the south remained around 809°/day as of late 2015 (no clear rotation signal for southern SKR in 2016). When Cassini shifted to high inclination orbits at the end of 2016, a single modulation signal of the narrowband emission showed up around 800°/day. A rotational modulation signal for northern auroral hiss also showed up around 800°/day, but there was no signal for the southern auroral hiss.

On the Cyclotron Maser Instability in magnetospheres of Hot Jupiters - Influence of ionosphere models. Planetary Radio Emissions|PLANETARY RADIO EMISSIONS VIII 8|
Mathematics, Physics and Space Research
A study of the plasma conditions in the atmosphere and ionosphere of the Hot Jupiter HD 209458b and for an HD 209458b-like planet at orbit locations of 0.2– 1 AU around a Sun-like star is presented. It is discussed how these conditions influence the radio emission expected from the planet’s magnetosphere. We find that the cyclotron maser instability (CMI) most likely will not operate at Hot Jupiters. It is found that close–in gas giants possess hydrodynamically expanding atmospheres and extended ionospheres with too high plasma densities within their magnetospheres, i.e. the plasma frequency is much higher than the cyclotron frequency, which is a contradiction to the necessary condition for the production of radio emission and also prevents the escape of radio waves for close–in extrasolar planets at distances <0.05 AU from a Sun-like host star. The structure of the upper atmosphere of Hot Jupiters around stars similar to the Sun changes for orbital distances between 0.2 and 0.5 AU from the hydrodynamic to a hydrostatic regime. This results in conditions where the plasma frequency can be lower than the cyclotron frequency, because a region of depleted plasma between the exobase and magnetopause can form. Like for e.g. Earth, in such an environment a beam of highly energetic electrons can propagate and be accelerated along the field lines towards the planet to produce radio emission. We also investigate the possible radio emission of the Hot Jupiter Tau Bootis b by placing it at different orbital distances from the host star, i.e. 0.046, 0.1 and 0.2 AU. It is checked if the atmosphere of Tau Bootis b at 0.046 AU is in the hydrodynamic or hydrostatic regime. In the hydrodynamic regime its ionosphere is extended and constitutes an obstacle for possibly generated radio waves; also, the generation via the Cyclotron Maser Instability (CMI) might be fully prevented.

Radio signatures of lightning discharges on Saturn have first been discovered by the Voyager spacecraft in 1980/81. After the Voyager flybys, the next sets of measurements only became available in 2004, when the Cassini spacecraft approached Saturn. Since then, Cassini provides continuous monitoring of Saturn’s lightning activity. In 2006, ground-based observations became available as a complementary source of information. Using a new broadband receiver at the UTR-2 radio telescope (Ukraine), Saturn lightning was observed over the whole spectral range of the instrument (10-30 MHz). This allows study of the temporal fine structure of the emission with a much finer temporal resolution than that of the routine satellite observations. More recently, Saturn lightning was also observed by two further ground-based radiotelescopes, namely WSRT (the Netherlands) and LOFAR (Europe). We present first results of recent ground-based observations of Saturn lightning performed with the radiotelescopes UTR-2, WSRT and LOFAR, and we describe the aims of future observations using these instruments.

Exploration of Jupiter’s Polar Magnetosphere and Radio Emissions with the Juno Mission (invited; abstract). Planetary Radio Emissions| PLANETARY RADIO EMISSIONS VII 7|
Bolton, S.
Mathematics, Physics and Space Research
Juno is the next mission to Jupiter. Juno’s overarching scientific goal is to understand the origin and evolution of Jupiter. As the archetype of giant planets, Jupiter holds the key to understanding the origin of our own solar system and the origin of the extra-solar planetary systems now being discovered around other stars. Juno’s investigation of Jupiter focuses on four themes: Origin, Interior Structure, Atmospheric Composition and Dynamics, and the Polar Magnetosphere. Juno’s scientific measurements include global maps of the gravity and magnetic fields, microwave radiometry of Jupiter’s deep atmosphere and a full suite of fields and particles measurements of Jupiter’s polar magnetosphere. Juno’s 32 polar orbits extensively sample Jupiter’s full range of latitudes and longitudes. High sensitivity radiometric measurements yields information on Jupiter’s deep atmosphere (down to ~1000 bars) which will be used to infer the global abundance of water, and to investigate the complex meteorology of Jupiter’s atmosphere. Determining the Jovian water abundance and whether a solid core exists within Jupiter permits discrimination between various scenarios of the formation of Jupiter. The gravity data constrain the planet’s interior rotation, core size and interior structure. The magnetic field measurements investigate how the interior dynamo works and examine the depth of generation of Jupiter’s powerful magnetic field. Fields and particles measurements as well as UV and IR polar images investigate Jupiter’s auroral physics to determine what drives Jupiter’s remarkable northern and southern lights. An overview of the mission and science objectives will be presented with an emphasis on Juno’s investigation of Jupiter’s polar magnetosphere and radio emission.

Jupiter's Io-C and Io-B decametric emission source morphology from LWA1 data analysis. Planetary Radio Emissions|PLANETARY RADIO EMISSIONS VIII 8|
Mathematics, Physics and Space Research
The information about Jupiter’s decametric radio source locations is a very important key to understand the emission mechanism. By using the modulation lanes in the dynamic spectra of Jupiter’s decametric emissions we developed a remote sensing tool to investigate Jupiter’s radio source locations. This modulation lane method provides a very unique opportunity to know the source locations. Recently we have used it with data taken by the Long Wavelength Array Station 1 (LWA1). The high sensitivity of the LWA1 allows us to measure the slope of the modulation lanes more precisely for many Io–related sources in comparison to previous observations. The source locations and beam parameters can be calculated by these slope measurements. In this analysis we found the existence of two independent radio sources in the case of Io-C and Io-B events. We named the new components Io-C’ (Io-C–prime) and Io-B’ (Io-B–prime).

The search for radio emission from exoplanets using LOFAR low-frequency beamformed observations: Data pipeline and preliminary results for the 55 Cnc system. Planetary Radio Emissions|PLANETARY RADIO EMISSIONS VIII 8|
Mathematics, Physics and Space Research
Detection of radio emission from exoplanets can provide information on the star– planet system that is difficult to study otherwise, such as the planetary magnetic field, magnetosphere, rotation period, interior structure, atmospheric dynamics and escape, and any star–planet interactions. Such a detection in the radio domain would open up a whole new field in the study of exoplanets. However, currently there are no confirmed detections of an exoplanet at radio frequencies. In this study, we search for non-thermal radio emission from the 55 Cnc system which has 5 known exoplanets. According to theoretical predictions 55 Cnc e, the innermost planet, is among the best targets for this search. We observed for 18 hours with the Low-Frequency Array (LOFAR) Low Band Antenna in the frequency range 26– 73 MHz with full polarization and covered 85% of the orbital phase of 55 Cnc e. During the observations four digital beams within the station beam were recorded simultaneously on 55 Cnc, nearby “empty” sky, a bright radio source, and a pulsar. A pipeline was created to automatically find and mask radio frequency interference, calibrate the time–frequency response of the telescope, and to search for bursty planetary radio signals in our data. Extensive tests and verifications were carried out on the pipeline. Analysis of the first 4 hours of these observations do not contain any exoplanet signal from 55 Cnc but we can confirm that our setup is adequate to detect faint astrophysical signals. We find a 3-sigma upper limit for 55 Cnc of 230 mJy using the pulsar to estimate the sensitivity of the observations and 2.6 Jy using the time series difference between the target and sky beam. The full data set is still under-going analysis. In the near future we will apply our observational technique and pipeline to the most promising exoplanet candidates for which LOFAR observations have already been obtained.

Studies of flare stars at radio waves are an important task of modern radio astronomy. They are connected with investigations of the physics of the stellar wind and stellar-planetary interrelations including habitable zones. One special interest is the search for radio emission bursts at extremely low frequencies (decameter wavelength). According to the analogy with the solar bursts the low frequency stellar bursts radio emission are arising in the outer stellar wind. Simultaneous observations at low frequencies and higher frequencies (from centimeter to meter wavelengths) are important also for the improvement of the detection reliability as well as for the phenomenology studies. We demonstrate the possibility to observe flare star bursts in the decametric radio band with the 70-meter dish radio telescope RT-70 (Evpatoria, Ukraine).

Software-type Wave-Particle Interaction Analyzer (S-WPIA) by RPWI for JUICE: Science objectives and implementation. Planetary Radio Emissions|PLANETARY RADIO EMISSIONS VIII 8|

We present science objectives of the Software–type Wave–Particle Interaction Analyzer (S–WPIA), which will be realized as a software function of the Low- Frequency receiver (LF) running on the DPU of RPWI (Radio and Plasma Waves Investigation) for the ESA JUICE mission. S–WPIA conducts onboard computations of physical quantities indicating the energy exchange between plasma waves and energetic ions. Onboard inter–instruments communications are necessary to realize S–WPIA, which will be implemented by efforts of RPWI, PEP (Particle Environment Package) and J–MAG (JUICE Magnetometer). By providing the direct evidence of ion energization processes by plasma waves around Jovian satellites, S–WPIA increases the scientific output of JUICE while keeping its impact on the telemetry data size to a minimum; S–WPIA outputs 0.2 kB at the smallest from 440 kB waveform and particle raw data.

Ground-Level Detection of Auroral Kilometric Radiation (abstract). Planetary Radio Emissions| PLANETARY RADIO EMISSIONS VII 7|
Labelle, J.
Anderson, R. R.
Mathematics, Physics and Space Research
The Earth’s aurorae radiate away up to 1% of their energy in the form of radio waves, called Auroral Kilometric Radiation (AKR). The mechanism responsible for the emission, the electron cyclotron maser (ECM), produces similar emissions at other planets, in the solar atmosphere, and in astrophysical systems. AKR was not unambiguously identified until the 1970’s because its detection requires a suitably instrumented satellite. The ECM theory predicts radiation beamed outward that cannot penetrate the increasing magnetic field and electron density near the Earth. Nevertheless, there have been observations over the years of AKR-like radio signals detected by ground-based, rocket-borne, and low-earth orbiting satellite-borne instruments, raising the question of whether a mechanism exists by which AKR can penetrate to low altitudes. Here we show the first unambiguous evidence that AKR indeed penetrates to low altitudes on occasions. We identified three examples of AKR-like emissions detected with a ground-based radio receiver at South Pole Station, Antarctica, during a 9-day interval in July, 2004, when the Geotail satellite, monitoring AKR, had a field of view including the auroral field lines above the station. The AKR-like emissions detected at ground-level have the same frequenc–time structure as simultaneous AKR emissions detected on Geotail 115,000-190,000 km away from the Earth. Slight differences in the frequency extent of the emissions at the two locations can be explained by, for example, plasmaspheric screening of the emissions detected by Geotail. These observations represent the first coincident detections of AKR in space and on the ground. They require the existence of an as-yet unidentified mechanism to produce the ground-level emissions which are not predicted by ECM theory, they suggest that previous AKR-like emissions observed at low altitudes may indeed be AKR, and they require revision of the widely-held view that AKR is only detectable from space.

A model of the Jovian internal field derived from in-situ and auroral constraints. Planetary Radio Emissions|PLANETARY RADIO EMISSIONS VIII 8|
Mathematics, Physics and Space Research
The internal magnetic field of Jupiter is known to be highly multi-polar, not only from the direct measurements performed by the Voyager and Pioneer probes but also from the unusually complex shape of the northern auroral oval. The limited amount of data obtained from the Voyager and Pioneer flybys do not permit accurate determination of the topology of the magnetic field, as they barely constrain, even the octupole contribution to the field. This does not allow one to reproduce the position of the auroras nor satisfactorily explain the shape and frequency range of the Jovian radio arcs. Successive attempts have been made to constrain the higher– degree field using the position of the Io auroral footprint where the auroras are due to currents generated close to Io and carried along the magnetic field lines. Thus, the auroral spots should map to Io’s orbit. VIPAL, the latest model of this kind is a 5th degree model. However, the VIPAL model was limited by three factors: the main constraints come from a unique L-shell, the difficulty of mixing Jovigraphic and magnetic data, and the non-linearity of the problem. These issues lead to numerically demanding computations, with the scale of computation increasing as the square of the model degree. We have developed a new method for computing the magnetic field using in-situ and auroral constraints (ISaAC) which we have applied to the computation of the Jovian magnetic field, based on Voyager, Pioneer, Galileo magnetic measurements and constrained by Io’s, Europa’s and Ganymede’s auroral footprint locations.

Study of SED's emission parameters. Planetary Radio Emissions|PLANETARY RADIO EMISSIONS VIII 8|
Mathematics, Physics and Space Research
The present research is devoted to the study of parameters of Saturn Electrostatic Discharges (SED) according to the data obtained during the observations of the initial period of storm J (December 2010) or the so-called Great White Spot (GWS). The ground-based detection was provided by the Ukrainian radio telescope UTR-2 at frequencies from 8 to 33 MHz in a wide range of time scales: from the day–to–day SED investigations to the temporal fine structure study up to microseconds. In this paper we describe our methods of data cleaning and the search for Saturn lightning in detail. The sensitivity of the observations allowed us to resolve the temporal micro–structure of lightning discharges. We determined the average signal’s dispersion delay for a session equal to (4.4±0.8) · 10−5 pc cm−3. It is close to the predicted value along the ray path from the storm to the radio telescope.

Locating low frequency radio observatories on the lunar surface has a number of advantages, including fixed locations for the antennas and no terrestrial inteference on the far side of the moon. Here, we describe the Radio Observatory on the Lunar Surface for Solar studies (ROLSS), a concept for a near-side, low frequency, interferometric radio imaging array designed to study particle acceleration in the corona and inner heliosphere. ROLSS would be deployed during an early lunar sortie or by a robotic rover as part of an unmanned landing. The prime science mission is to image intense type II and type III solar radio bursts with the aim of determining the sites at and mechanisms by which the radiating particles are accelerated. Secondary science goals include constraining the density of the lunar ionosphere by searching for a low radio frequency cutoff of the solar radio emissions and detecting the low energy electron population in astrophysical sources. Furthermore, ROLSS serves as a pathfinder for larger, far-side lunar radio arrays, designed for faint sources.

Saturnian Low-Frequency Drifting Radio Bursts: Statistical Properties and Polarization. Planetary Radio Emissions| PLANETARY RADIO EMISSIONS VII 7|

Leisner, J. S.
Taubenschuss, U.
Mathematics, Physics and Space Research
After Cassini’s arrival at planet Saturn, its Radio and Plasma Wave Science (RPWS) experiment has performed numerous observations of a new type of planetary radio emissions in the lower kHz frequency range (< 50kHz). These bursty emissions have time scales of a few to 15 minutes and occur as slowly drifting events in the time-frequency spectrogram. They have neither been detected by the Voyager spacecraft nor by Ulysses. As a first approach to this new phenomenon, results of a statistical study with regard to the observer’s position, i.e. Cassini’s orbital position, will be presented. Furthermore, aspects of polarization will be highlighted as far as appropriate goniopolarimetric (3-antenna) observations are available.

Medium-Frequency Burst Emissions: A Terrestrial Analog to Solar Type III Bursts?. Planetary Radio Emissions| PLANETARY RADIO EMISSIONS VII 7|
Labelle, J.
Mathematics, Physics and Space Research
Auroral Medium Frequency Burst (MFB) is the least understood of three types of terrestrial auroral emissions detectable at ground level. MFB consists of broadband (500-2000 kHz) left-polarized impulsive emissions typically occurring for a few minutes at the onset of polar substorms, one of the most energetic phenomena in the terrestrial magnetosphere. Recent observations of the source location and fine structure of MFB provide the best opportunity yet to test theoretical models of the generation mechanism. Proposed mechanisms include mode conversion of Langmuir or electron cyclotron sound waves excited via resonant interactions with auroral electrons; the former has been shown under certain conditions to predict the frequency-time characteristics of MFB fine structure.

Feasibility of the exploration of the subsurface structures of Jupiter's icy moons by interference of Jovian hectometric and decametric radiation. Planetary Radio Emissions|PLANETARY RADIO EMISSIONS VIII 8|
Mathematics, Physics and Space Research
A new passive subsurface radar technique using interference patterns in the spectrum of the Jovian hectometric and decametric radiation (HOM/DAM) has been proposed, and investigated for implementation on JUICE (Jupiter Icy Moons Explorer)/ RPWI (Radio and Plasma Wave Instrument). When there occurs interference among Jovian radio waves directly from Jupiter (W1), those reflected at the ice crust surface (W2), and those reflected at the subsurface reflectors in the ice crust (W3), fine and wide interference patters can be found in the spectrum. Fine patterns are caused by interference between W1 and W2, and between W1 and W3. Wide patterns are caused by interference between W2 and W3. In order to observe these interference patterns, the receiver of JUICE/RPWI is required to resolve 100 Hz, and possess a downlink spectra with a frequency range of 2 MHz and resolution of 1 kHz. Based on the calculation of the attenuation rate of the radio waves in the ice from 80 K (surface) to 250 K (just above the subsurface ocean), the intensity of the subsurface echo was estimated. The radar waves are expected to reach just above the ice crust/liquid ocean boundary. However, due to extremely high attenuation, it is difficult to detect the echoes from ice crust/liquid ocean boundary. In order to apply the new passive subsurface radar methods, the duration of the coherence of the Jovian radio wave should be long enough (>3.3 ms if spacecraft’s altitude is 500 km).

Solar imaging using low frequency arrays. Planetary Radio Emissions|PLANETARY RADIO EMISSIONS VIII 8|
OBEROI, D.
LIND, F.
MORGAN, J.
McCAULEY, P.
Mathematics, Physics and Space Research
Low frequency imaging radio arrays such as MWA, LWA and LOFAR have been recently commissioned, and significantly more advanced and flexible arrays are planned for the near term. These powerful instruments offer new opportunities for direct solar imaging at high time and frequency resolution. They can also probe large volumes of the heliosphere simultaneously, by virtue of very large fields of view. They allow highly detailed, spatially resolved study of solar and heliospheric radio bursts, which are complemented by heliospheric propagation studies using both background astronomical radio emissions as well as the bursts themselves. In this paper, the state of the art in such wide field solar and heliospheric radio studies is summarized, including recent results from the Murchison Widefield Array (MWA). The prospects for major advances in observational capabilities in the near future are reviewed, with particular emphasis on the RAPID system developed at Haystack Observatory.

On the Possibility of Radio Emission of Planets Around Pulsars. Planetary Radio Emissions| PLANETARY RADIO EMISSIONS VII 7|
Mottez, F.
Mathematics, Physics and Space Research
A planet orbiting around a pulsar would be immersed in an ultra-relativistic under-dense plasma flow. It would behave as a unipolar inductor, with a significant potential drop along the planet. As for Io in Jupiter’s magnetosphere, there would be two stationary Alfv´en waves, the Alfv´en wings (AW), attached to the planet. The AW would be supported by strong electric currents, in some circumstances comparable to those of a pulsar. It would be a cause of powerful radio waves emitted all along the AW, and highly collimated through relativistic aberration. There would be a chance to detect these radio-emissions from Earth. The emission would be pulses as for ordinary pulsars; their occurrence would depend on the planet-star-observer angle. These results are still preliminary, further work needs to be done.

Generation of Auroral Kilometric Radiation in a dipole magnetic field: 3-D approach. Planetary Radio Emissions|PLANETARY RADIO EMISSIONS VIII 8|
Mathematics, Physics and Space Research
We have investigated the propagation and amplification of Auroral Kilometric Radiation (AKR) in a narrow three-dimensional plasma cavity, in which a weakly relativistic electron beam propagates along the magnetic field. Both electron beam velocity components, parallel and perpendicular to the magnetic field are taken into account. Although the energy of transverse electron motion serves as a source of free energy for the development of electron cyclotron maser instability, it is found that for correct description of the AKR spectrum formation it is necessary to take the velocity component of electron motion directed along the magnetic field into account, because it gives a possibility for wave generation in a much wider frequency range. The results of calculations performed for thousands of waves have strengthened the assumption made in our previous paper [Burinskaya, 2013] on a basis of calculations for several waves, that the main factor, determining the wave energy at the time of wave escape from a source, is the duration of wave lifetime inside an amplification region. Thus, the global magnetic field inhomogeneity plays a key role in the formation of the AKR spectrum, because it defines for each wave its lifetime inside an amplification region and, by this means, the wave spectral intensity.

Low frequency solar scrutiny with the Polish LOFAR stations. Planetary Radio Emissions|PLANETARY RADIO EMISSIONS VIII 8|
Mathematics, Physics and Space Research
The LOw–Frequency ARray (LOFAR) is a radio interferometer operating in the frequency range 10 – 240 MHz (corresponding to wavelengths of 30 – 1.2 m). Important issues of its broad scientific program are the solar and space weather investigations. We are expecting that the LOFAR telescope will bring interesting results in these fields. Three new LOFAR stations were built in Poland in 2015 and have been operating since the beginning of 2016. By including these stations to the ILT (International LOFAR Telescope), the resolution and sensitivity of the whole interferometer were improved and they are, for 240 MHz, 0.1 arcsec and 9.17 mJy/beam, respectively. Using a single LOFAR station, spectroscopic observations of the Sun can be performed; more stations allow us to obtain solar radio images.

The Nançay Decameter Array (NDA) routinely observes low frequency (10– 100 MHz) radio emissions of Jupiter and the Sun since 4 decades. The NDA observations, acquired with a variety of receivers with increasing performances, were the basis for numerous studies of Jovian and solar radio emissions and now form a unique long-term database spanning ≥ 3 solar cycles and Jovian revolutions. In addition, the NDA historically brought a fruitful support to space-based radio observatories of the heliosphere, to multi-wavelength analyses of solar activity and contributes to the development of space weather services. After having summarized the NDA characteristics, this article presents latest instrumental and database developments, some recent scientific results and perspectives for the next decade.

Santolik, O.
Averkamp, T. F.
Kurth, W. S.
Mathematics, Physics and Space Research
The Cassini Radio and Plasma Wave instrument has detected whistler-mode chorus during many of its one hundred thirty-five orbits of Saturn. Similar to observations of chorus in Earth’s magnetosphere, the chorus at Saturn is found to always be propagating away from Saturn’s magnetic equator, suggesting a source near the magnetic equator. Unlike chorus at Earth, the chorus at Saturn is only observed below half the electron cyclotron frequency unless it is detected in association with a local plasma injection event. This work will expand our earlier survey of chorus observations from the first forty-five orbits of Cassini and discuss the similarities and differences of the two types of chorus detected at Saturn to observations of chorus at Earth and Jupiter.

Propagation of Energetic Electrons from the Corona into Interplanetary Space and Type III Radio Emission. Planetary Radio Emissions| PLANETARY RADIO EMISSIONS VII 7|
Vocks, C.
Breitling, F.
Mann, G.
Mathematics, Physics and Space Research
During solar flares a large amount of electrons with energies greater than 20 keV is generated with a production rate of typically 1036 s-1. A part of them is able to propagate along open magnetic field lines through the corona into interplanetary space. During their travel they emit radio radiation which is observed as type III radio bursts in the frequency range from 100 MHz down to 10 kHz by the WAVES radio spectrometer aboard the spacecraft WIND, for instance. From the drift rates of these bursts in dynamic radio spectra the radial propagation velocity Vr of the type III burst exciting electrons is derived by employing a newly developed density model of the heliosphere. Calculations show that the radio radiation is emitted by electrons with different Vr and therefore by different electrons of the initially produced electron distribution.

Variability of Jupiter’s Synchrotron Emission in Mid-2009. Planetary Radio Emissions| PLANETARY RADIO EMISSIONS VII 7|

Sault, R.

Levin, S.
Mathematics, Physics and Space Research
In the present paper, radio observations made at the wavelength of 6 cm with the VLA in 2009 are analyzed. Reconstructed images of the brightness distribution show significant intensity variations of the equatorial peak emissions on both sides of the planet. The fluctuations are characterized by asymmetrical changes in the brightness distributions. The contribution of a comet-like impact to the observed variations is discussed. During the third week of July, ground-based measurements at different radio bands confirmed that a large projectile had struck Jupiter’s atmosphere. The examination of the 2009 VLA data sets shows that the steep enhancement of the emission radiated by Jupiter’s electron belt occurred during the same period. The increase in the synchrotron radiation was observed to go on for a couple of weeks before gradually fading in August. Two-dimensional reconstructions of the equatorial brightness distribution demonstrate that the time variability of the radio emission during the middle of 2009 was driven by the longitudinal expansion of an impact-related synchrotron “hot spot” originally located at the Jupiter System III longitude of 305 degrees.

Solar Orbiter is an M-class mission in the ESA Science Programme Cosmic Vision 2015 – 2025 having an orbit with perihelion as low as 0.28 AU. The Radio Plasma Waves (RPW) Analyzer on board will provide new insights into the microscale phenomenon, the propagation modes of the radio waves and the localization of their source regions. The three electric antennas (each 5 meters long) are designed to be mounted on booms in a perpendicular plane to the spacecraft-Sun axis. Effective antenna lengths and directions are different from the physical ones due to their coupling with the spacecraft body. These parameters have been investigated considering various antenna placements on the spacecraft body [Rucker et al., this issue]. Results indicate that all effective antenna directions will be slightly tilted towards the Sun. This paper discusses a possible accuracy of the Direction Finding (DF) with respect to this tilt angle and uncertainties of the effective antenna parameters.

Earth-orbiting satellites have routinely traversed the source regions of auroral kilometric radiation. This radio emission is generated via the cyclotron maser instability very close to the electron cyclotron frequency. While Cassini’s orbit has crossed auroral field lines, the radial distance at auroral latitudes is typically too high for the analogous Saturn kilometric radiation source. However, on Oct. 17, 2008, the Radio and Plasma Wave Science instrument detected the kilometric radiation at and just below the electron cyclotron frequency. At this time the spacecraft was at a distance of 5 Saturn radii, at 0.9 hours local time, and on L-shells in the range of 25 to above 30. Here the magnetic field suggests the corresponding current was directed upward, away from the planet. Low energy electron observations by the Cassini Plasma Spectrometer instrument suggest that growth of the SKR is likely due to an unstable shell-like distribution.

On the Origin of Io’s Ultraviolet Aurora. Planetary Radio Emissions| PLANETARY RADIO EMISSIONS VII 7|
Rucker, H. O.
Shaposhnikov, V. E.
Zatsev, V. V.
Mathematics, Physics and Space Research
A model involving an additional contribution to Io’s ultraviolet (UV) aurora is presented. A mechanism for heating of electrons of Io’s ionospheric plasma up to sufficient energies for the excitation of Io’s atmospheric oxygen and emitting of observed UV emission is proposed. The mechanism operates by the effect of the different magnetization of the electrons and ions in Io’s ionosphere which in the course of Io’s motion through the Jovian magnetic field causes the creation of a charge-separation electric field in the upstream part of the ionosphere. This field has a component parallel to the magnetic and shifts the electron distribution function relative to the ion distribution function by a value exceeding the thermal velocity of electrons. In this case, a Bunemann instability with a very large growth rate develops. This results in the excitation of turbulent pulsations at frequency close to the ion-sound frequency and the occurrence of anomalous resistance to the electric current. The latter causes heating of Io’s ionospheric electrons up to a temperature of about 25 eV. Atmospheric oxygen molecules excited by collisions with the heated electrons of Io’s ionosphere, whose density is about 6 × 104 cm-3, can contribute to the observed UV brightness. The proposed model permits one to explain the correlation of UV brightness with Io’s magnetic longitude and the discrepancy between the anti-Jovian equatorial UV spots and sub-Jovian spots as well.

Solar Observations with LOFAR. Planetary Radio Emissions| PLANETARY RADIO EMISSIONS VII 7|

Mathematics, Physics and Space Research
The LOw Frequency ARray (LOFAR) is a novel radio telescope that consists of 20 core stations near Exloo in the Netherlands, 18 Dutch remote stations, and 8 international stations all distributed over central Europe. One of them was built in Potsdam. LOFAR is a radio interferometer for the frequency range of 30-240 MHz and will exceed the sensitivity and resolution of existing instruments by more than one order of magnitude. ”Solar Physics and Space Weather with LOFAR” is one of LOFAR’s Key Science Projects. Since LOFAR is working in the frequency range of 30-240 MHz, it is able to deliver radio images of the Sun. The solar radio radiation in this frequency range is emitted from the outer corona. Since radio waves are strongly scattered in the corona, the angular resolution of LOFAR’s radio maps will be limited to a few 10 arcseconds. The necessary baselines include the core and the nearest remote stations.

Database of solar radio bursts observed by solar radio spectro-polarimeter AMATERAS. Planetary Radio Emissions|PLANETARY RADIO EMISSIONS VIII 8|
Mathematics, Physics and Space Research
Observations of solar radio bursts is a useful tool to study non-thermal electron acceleration and the plasma environment in the solar corona. The radio bursts in a frequency range from 150 to 500 MHz with fine temporal and spectral resolutions (10 ms and 61 kHz) have been observed with the AMATERAS radio spectro– polarimeter installed at the Iitate Planetary Radio Telescope since 2010. Here we review results obtained from the AMATERAS observation and introduce the database which is open to the public. The AMATERAS receiver consists of a wideband and low-noise front–end receiver and a digital spectrometer. Both right and left-hand polarized components are simultaneously observed. The combination of a large aperture area of the telescope and the digital receiver enables us to observe the radio burst with high dynamic range and fine spectral resolution. After a daily observation of the Sun, a data processing pipeline generates low and high resolution data sets. The low resolution data with reduced resolutions of 1 s, 1 MHz, and 8 bits is converted to the FITS format and distributed through the AMATERAS Data Center. Quick look (PNG format) and meta-data of the FITS–format file are registered to the Virtual European Solar and Planetary Access (VESPA) and Inter– university Upper atmosphere Global Observation NETwork (IUGONET) database. The high resolution data set has fine resolutions of 10 ms and 61 kHz, but the dynamic range is reduced to be 8 or 16 bits depending on the intensity of the radio burst observed. It is currently provided on request basis. ∗
