    • The association of a J -burst with a solar jet 

      GALLAGHER, PETER; Morosan, D.E.; Fallows, R.A.; Reid, H.; Mann, G.; Bisi, M.M.; Magdalenić, J; Rucker, H.O.; Thidé, B.; Vocks, C.; Anderson, J.; Asgekar, A.; Avruch, I.M.; Bell, M.E.; Bentum, M.J.; Best, P.; Blaauw, R.; Bonafede, A.; Breitling, F.; Broderick, J.W.; Brüggen, M.; Cerrigone, L.; Ciardi, B.; de Geus, E.; Duscha, S.; Eislöffel, J.; Falcke, H.; Garett, M.A.; Grießmeier, J.M.; Gunst, A.W.; Hoeft, M.; Iacobelli, M.; Juette, E.; Kuper, G.; McFadden, R.; McKay-Bukowski, D.; McKean, J.P.; Mulcahy, D.D.; Munk, H.; Nelles, A.; Orru, E.; Paas, H.; Pandey-Pommier, M.; Pandey, V.N.; Pizzo, R.; Polatidis, A.G.; Reich, W.; Schwarz, D.J.; Sluman, J.; Smirnov, O.; Steinmetz, M.; Tagger, M.; ter Veen, S.; Thoudam, S.; Toribio, M.C.; Vermeulen, R.; van Weeren, R.J.; Wucknitz, O.; Zarka, P. (2017)
      Context. The Sun is an active star that produces large-scale energetic events such as solar flares and coronal mass ejections, and numerous smaller scale events such as solar jets. These events are often associated with ...

    • 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, ...

    • 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 ...

    • Follow-up radio observations of the τ Boötis exoplanetary system: preliminary results from NenuFAR 

      Turner, J. D.; Zarka, P.; Grießmeier, J.-M.; Mauduit, E.; Lamy, L.; Girard, J. N.; Kimura, T.; Cecconi, B.; Koopmans, L. V. E. (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 ...

    • 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 ...

    • PALANTIR: An updated prediction tool for exoplanetary radio emissions 

      Mauduit, E.; Grießmeier, J.-M.; Zarka, P.; Turner, J. D. (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 

      Lamy, L.; Duchêne, A.; Mauduit, E.; Zarka, P.; Yerin, S.; Louis, C.; Griessmeier, J.-M.; Girard, J.; Theureau, G. (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 ...

    • Re-exploring the radio spectrum of Uranus in orbit: science case and digital high-frequency receiver 

      Lamy, L.; Cecconi, B.; Dekkali, M.; Zarka, P.; Briand, C.; Moncuquet, M.; Pantellini, F.; Griton, L.; Boudouma, A.; Bonnin, X.; Astier, P.-L.; Dias, D.; Gamage, V.; Collet, B.; Louis, C. (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 ...
