Auroral emissions and inner magnetospheric dynamics during Earth's response to the 28th October 2021 Coronal Mass Ejection
Waters, J. E.; Jackman, C. M.; Whiter, D. K.; Fogg, A. R.; Lamy, L.; Carter, J. A.; Coxon, J. C.; Fryer, L.; Louis, C. K.; Paxton, L. J.; Briand, C.; Cecconi, B.; Issautier, K.; Bonnin, X.; Gallagher, P. (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 ... -
Characterization of Jovian hectometric sources with Juno: statistical position and generation by shell-type electrons
Collet, B.; Lamy, L.; Louis, C. K.; Zarka, P.; Prangé, P.; Louarn, P.; Sulaiman, A.; Kurth, W. S. K. (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, ... -
Comparative visibility of planetary auroral radio emissions and implications for the search for exoplanets
Lamy, L.; Waters, J. E.; Louis, C. K. (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 ... -
First Analysis of the Effect of the Jovicentric Declination of the Earth on the Observation of Jovian Decametric Radio Emissions
Jácome, H. R. P.; Marques, M. S.; Zarka, P.; Echer, E.; Lamy, L.; Louis, C. K. (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 ... -
Latitudinal distribution of auroral kilometric radiation based on Polar spacecraft observations
Louis, C. K.; Smith, K. D.; Jackman, C. M.; Fogg, A. R.; Waters, J. E.; O'Dwyer, E. P.; Granroth, L. (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
Boudouma, A.; Zarka, P.; Magalhães, F. P.; Marques, M. S.; Louis, C. K.; Echer, E.; Lamy, L.; Prangé R. (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 ... -
Predictions for Uranus-moons radio emissions and comparison with Voyager 2/PRA observations
Jackman, C. M.; Cecconi, B.; Hess, S. L. G.; Louis, C. K.; Lamy, L. (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 ... -
Selection of low frequency extensions of Saturn kilometric radiation
O'Dwyer, E. P.; Jackman, C. M.; Domijan, K.; Lamy, L.; Louis, C. K. (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 ... -
Testing the relationship between Saturn's ENA and narrowband radio emissions
Kinrade, J.; Badman, S. V.; Paranicas, C.; Jackman, C. M.; Louis, C. K.; O'Dwyer, E. P. (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 ... -
Using crossings of Saturn's magnetospheric boundaries to explore the link between upstream conditions and radio emission
Jackman, C. M.; O'Dwyer, E. P.; Louis, C. K.; Fogg, A. R.; Waters, J. E.; Lamy, L. (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 ...
