Scales of wave-particle interaction processes in Jupiter's magnetosphere: Implications for JUNO/JEDI measurements

We investigate the occurrence and the role of various wave-particle interaction processes, such as Landau damping and cyclotron heating, in Jupiter's magnetosphere. Therefore we calculate kinetic spatial and temporal scales, i.e., cyclotron frequencies, gyro radii and inertial length scales, for electrons and multiple ion species, respectively. We cross-compare these scales at various regions within Jupiter's magnetosphere and investigate the roles of the possible wave-particle mechanisms in each region, e.g., Jupiter's plasma sheet, the auroral acceleration region, and Jupiter's polar ionosphere. We thereby consider that the magnetospheric regions are coupled through convective transport, and Alfven and other wave modes. Our results will aid the interpretation of electron and ion distribution functions measured by the JEDI instrument onboard the JUNO spacecraft.
