Outline of Final Research Achievements

This study defined a new auroral intensity ratio according to the wavelength range of Hisaki space telescope and we developed a method deriving auroral electron density, flux, and magnetospheric parameters from the observation. We evaluated the method by comparing them with observations using the Hubble space telescope. Applying this method, we found the characteristic time variations of Jupiter aurora and magnetospheric plasma responding to the inner-driven (i.e., Jupiter rotation and Io volcanic activity) and outer-driven (i.e., solar wind) variations. We applied H/H2 intensity ratio which is sensitive to the low-energy aurora electron to the Jupiter aurora and discussed similarity and difference compared to the Saturn aurora.
