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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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, ... -
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 ...
