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" ... -
Auroral emissions and inner magnetospheric dynamics during Earth's response to the 28th October 2021 Coronal Mass Ejection
(Dublin Institute for Advanced Studies, 2023)On 28th October 2021 the Sun released a large Coronal Mass Ejection (CME) in Earth's direction. An X1.0 class solar flare and a rare ground level enhancement (GLE) were observed, along with bright solar radio bursts. Here ... -
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, ... -
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, ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
First Analysis of the Effect of the Jovicentric Declination of the Earth on the Observation of Jovian Decametric Radio Emissions
(2023)Through analysis of the extensive catalog of the Nan cay Decameter Array, from 1978 to 2020, we demonstrate that the effect of the variation of the Jovicentric declination of the Earth on the visibility of Jovian decametric ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ...
