| Outline of Final Research Achievements |
The purpose of this study is to clarify the atmosphere-magnetosphere coupling in Jupiter using continuous monitoring data of planetary atmosphere and plasma phenomena obtained with our observation facilities at the summit of Haleakala, Hawaii (altitude 3000 m). In the summer of 2014, the Tohoku University 60 cm telescope was relocated to Haleakala, and we started continuous observation of Io’s sulfur ion torus emission at 673 nm with a visible high-resolution spectrograph. Furthermore, we carried out simultaneous observation of Io’s torus emission and Jupiter’s aurora in the ultra-violet range with a planetary space telescope Hisaki/EXCEED, and examined the causal relationship between the Io torus dynamics and the Jupiter auroral activity associated with the activation of Io’s volcano particularly for the events occurred in January 2015. In addition, we performed the precise observation of Jupiter infrared aurora using the Subaru telescope and NASA/IRTF every year.
