Outline of Final Research Achievements |
(1) Relativistic electron acceleration in a high Mach number parallel shock: A high Mach number case was found in the Kronian bow shock observations and enabled opportunities of in-situ observations of plasma physics of high Mach number shocks. The high Mach number parallel shock showed relativistic acceleration of electrons. (2) Driver of the Jovian magnetospheric dynamics: Two competing ideas for the Jovian magnetospheric activities are plasma degassing from the innermost satellite of Io and variation in the solar wind. The JAXA Hisaki mission that provides continuous monitoring of the Jovian system enabled us to tell how the two factors collaborate to determine the Jovian auroral activity. (3) High energy particle detector onboard a Jupiter mission: Light-weight in-situ particle instruments that works under the harsh environment of the Jovian magnetosphere has been designed and its performance has been tested.
