Investigation of the features of heavy ion acceleration events in the Jovian magnetotail using Juno/JEDI data

Our solar system contains a variety of planetary magnetospheres, which are known to be very efficient accelerators of charged particles. The energization processes of magnetotail plasma populations are thought to share similarities among the various magnetospheres. In the present study, we investigate the characteristics of ion acceleration processes in the Jovian magnetosphere, which contains a variety of ion species with different charge states, resulting in a diverse set of acceleration-relevant factors that can be tested. In this study, we use magnetic field data from the MAG instrument, and energetic ion data from the JEDI instrument onboard the Juno mission, in order to investigate the energization of hydrogen (~50 keV to ~1 MeV), oxygen (~170 keV to ~2 MeV) and sulfur (~170 keV to ~4MeV) ions during dipolarization events in the Jupiter’s magnetosphere. Results of our study are a first step towards a comparative analysis of the energization processes around the dipolarization events in the Jupiter’s and Earth’s magnetotails.
