Evidence of fresh injections related to the interchange instability in the Io torus
(2023)The Juno Waves instrument often detects brief, band-limited emissions when the spacecraft crosses magnetic fields threading Io's M-shell, or vicinity thereof, up to about 35 degrees magnetic latitude. The disturbances have ... -
Testing the relationship between Saturn's ENA and narrowband radio emissions
(2023)Saturn's kilometric radiation (SKR) and Energetic Neutral Atom (ENA) emissions are important remote diagnostics of the planet's magnetospheric dynamics, intensifying during periods of global-scale plasma injection, and ... -
Probing Jupiter-satellite interactions from the beaming of their decametric emissions: the case of Europa and Ganymede
(2023)In a recent study, we accurately measured the beaming of Io-Jupiter decametric emissions, whose uncertainty is controlled by that on the position of the active Io ux tube (IFT) hosting the radiosources. The active IFT was ... -
Re-exploring the radio spectrum of Uranus in orbit: science case and digital high-frequency receiver
(2023)Among the known planetary magnetospheres, those of Uranus and Neptune display very similar radio environments so that they were referred to as radio twins. Their pioneering exploration by the Voyager 2 Planetary Radio ... -
Comparative visibility of planetary auroral radio emissions and implications for the search for exoplanets
(2023)The auroral regions of the so-called radio planets are the source of powerful, non-thermal, radio emissions amplified by an electron-wave resonant instability. These emissions are produced near the planetary magnetic poles ... -
Predictions for Uranus-moons radio emissions and comparison with Voyager 2/PRA observations
(2023)Jupiter's and Saturn's moons are known to induce auroral emission in the Ultraviolet wavelengths. At Jupiter, the moons Io, Europa and Ganymede are also responsible for powerful decametric radio emissions, driven by the ... -
Solar/Stellar Atmospheric Tomography with mm-radio Snapshot Spectroscopic Imaging
(2023)Millimeter (mm) frequencies are primarily sensitive to thermal emission from layers across the stellar chromosphere up to the transition region, while metre-wave (radio) frequencies probe the coronal heights. Together the ... -
Follow-up radio observations of the τ Boötis exoplanetary system: preliminary results from NenuFAR
(2023)Studying the magnetic fields of exoplanets will provide valuable information about their interior structures, atmospheric properties (escape and dynamics), and potential habitability. One of the most promising methods to ... -
A particular form of Saturn kilometric radiation at the low end of its spectrum
(2023)We studied the spectral morphology of Saturn kilometric radiation (SKR) with the Cassini RPWS (Radio and Plasma Wave Science) instrument and found a particular structure at very low frequencies which we nicknamed "caterpillar" ... -
On the required mass for an exoplanet to emit radio waves
(2023)The detection of radio emission from an exoplanet would constitute the best way to determine its magnetic field. Indeed, the presence of a planetary magnetic field is a necessary condition for radio emission via the Cyclotron ... -
A consolidated catalogue of jovian decametric radio observations observed in Nançay from January 1978 to December 1990
(2023)A series of five Jovian decametric radio emission catalogues covering 13 years of observations (1978 to 1990) and published between 1981 and 1993 has been compiled after a digitisation process. The new catalogue has been ... -
Ground support of Juno mission and RFI mitigation
(2023)Joint observations provide much more useful data and improve the quality of the analysis. But to obtain high-quality results, it is often necessary to improve the algorithms of the processing program. Radio frequency ... -
Plasma waves in the very local interstellar medium: a brief review
(2023)The Plasma Wave Science instruments on the two Voyager spacecraft are providing observations of plasma waves in the very local interstellar medium. One of the most important aspects of these observations are the inferred ... -
A method for the automatic detection of solar type III radio bursts with Wind/Waves
(2023)Solar type III radio bursts have a characteristic signature in frequency-time dynamic spectrograms and provide important insight into the dynamics of the Sun and solar wind. Direct physical inferences of the source electrons ... -
Electron densities in Jupiter's polar regions from the identification of Ordinary-mode wave cutoffs
(2023)The electron density is a critical parameter for understanding auroral processes; namely, electron acceleration via Alfvénic dissipation, electrostatic acceleration, as well as the generation and propagation of radio and ... -
Using crossings of Saturn's magnetospheric boundaries to explore the link between upstream conditions and radio emission
(2023)Saturn has several components to its radio emission which can change in response to varying solar wind and magnetospheric conditions. These radio components include the Saturn Kilometric Radiation (SKR), a cyclotron maser ... -
Latitudinal distribution of auroral kilometric radiation based on Polar spacecraft observations
(2023)Auroral Kilometric Radiation (AKR) is a terrestrial radio emission that occurs above the poles. It is produced by the cyclotron maser instability at frequencies close to the electron cyclotron frequency (proportional to ... -
PALANTIR: An updated prediction tool for exoplanetary radio emissions
(2023)In the past two decades, it has been convincingly argued that magnetospheric radio emissions, of cyclotron maser origin, can occur for exoplanetary systems, similarly as solar planets, with the same periodicity as the ... -
Selection of low frequency extensions of Saturn kilometric radiation
(2023)Saturn's Kilometric Radiation is an auroral emission that occurs between a few kHz to 1.2 MHz, and peaks in the frequency range 100-400 kHz (Kaiser et al., 1984). It was detected quasi-continuously by Cassini from its ... -
Classification of the spectral fine structure in auroral kilometric radiation
(2023)Auroral Kilometric Radiation (AKR) is generated by unstable energetic electron populations in the auroral region of Earth's magnetosphere. A mechanism known as the cyclotron maser instability amplifies weak background ...
