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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
Jupiter Long Dispersion Lightning Whistlers that propagate through the Io torus: Juno Observations
(2023)The detection of lightning whistlers in planetary magnetospheres can provide valuable information about the properties of both the source lightning, and the plasma environment along the whistler propagation path. The Juno ... -
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 ... -
Statistical characteristics of leaked AKR observed at South pole station, Antarctica
(2023)There is mounting evidence of a component of terrestrial auroral kilometric radiation (AKR) that is converted to whistler mode and radiated downward toward the planet, observable even at ground level. Three years of data ... -
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 ... -
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 ... -
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 ... -
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 ... -
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" ... -
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 ... -
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 ... -
Localisation of the main HOM source in the dusk side of the Jovian magnetosphere
(2023)It was suggested in Zarka et al. (2021) that the most intense Jovian hectometric emissions (HOM) originate from the dusk side of the Jovian magnetosphere. These authors showed that the distribution of the main HOM observed ... -
The radio JOVE Project 2.0
(2023)Radio JOVE (radiojove.gsfc.nasa.gov) is a well-known public outreach, education, and citizen science project using radio astronomy and a hands-on radio telescope for science inquiry and education. Radio JOVE 2.0 is a new ... -
Characterization of Jovian hectometric sources with Juno: statistical position and generation by shell-type electrons
(2023)The Juno orbiter has been exploring the polar magnetosphere of Jupiter since mid-2016. Thanks to its unique polar trajectory, it has crossed regularly the north- ern and southern sources of auroral hectometric radiation, ... -
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 ... -
The peak frequency source of Saturn's kilometric radiation
(2023)In 2016-2017, the Cassini spacecraft explored the source regions of Saturn0s Kilometric Radiation (SKR) within the kronian polar magnetosphere before ultimately plunging into the upper atmosphere of the planet. This powerful, ...
