Outline of Final Research Achievements

Aim of our study is to reveal release and transport processes of electromagnetic energy in Jupiter's magnetosphere, which accelerates plasma particles up to 10s MeV energies. Based on the first-ever coordinated observations with the Hisaki satellite, Hubble Space Telescope, and Juno explorer, we successfully captured spatio-temporal variations in Jupiter's aurora that is 'internally-driven' by Jupiter's rotation and strong magnetic field. The observed variations in the aurora tells us that energies of the rotation and magnetic field stored in the magnetosphere are rapidly released within one rotation and transported toward Jupiter.

Academic Significance and Societal Importance of the Research Achievements

本研究で明らかになったエネルギー開放・輸送過程は、中性子星磁気圏など他の回転磁化天体が形成する磁気圏にも普遍的に存在する可能性がある。本研究で得られた知見を他天体に応用すれば、直接探査が不可能な天体における宇宙環境の理解などに寄与する。
