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 ... -
Five years of solar observations with LOFAR station in Baldy
(2023)We present exemplary observations of solar radio bursts collected in 2017 – 2021 with the use of LOFAR station PL612 located in Baldy (Poland), operating in local mode. In that period, the Sun was observed for 1190.3 hours ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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" ... -
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 ... -
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 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 ... -
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 ... -
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 ... -
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 ... -
Automatic detection of solar radio bursts in NenuFAR observations
(2023)Solar radio bursts are some of the brightest emissions at radio frequencies in the solar system. The emission mechanisms that generate these bursts offer a remote insight into physical processes in solar coronal plasma, ... -
The Science Behind SURROUND: a Constellation of Cubesats Around the Sun
(2023)One of the greatest challenge facing current space weather monitoring operations is forecasting the arrival of coronal mass ejections (CMEs) and Solar Energetic Particles (SEPs) within their Earth-Sun propagation timescales. ... -
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 ...
