| Outline of Final Research Achievements |
We Tohoku Univ. have operated 40cm telescope at Mt. Haleakala of Maui Island by the cooperation with Univ. Hawaii. Utilizing its wide FOV and high dispersion spectroscopic capabilities, we investigated (1) the origin of the variations of Herman sodium atmosphere (with NASA/MESSENGER orbiter), (2) the effects of Io torus to Jovian magnetospheric activities (with JAXA/Hisaki EUV space telescope). We also investigated following targets by related telescope and satellites; (3) the search of escaping atmospheres of Venus and Mars (by Hisaki); (4) the study of velocity field and trace gas elements in the upper atmosphere of Venus (at Kitt Peak, Hida, and Haleakala), and (5) the search of crust origin gas (H2O/HDO, CH4) in the Martian atmosphere (at Manua Kea, Haleakala). Moreover, at the Haleakala observatory, (6) we moved 60cm telescope from Iitate, Fukushima (first light: fall 2014), and constructed the 2m telescope (first light: the end of 2016) under the collaboration with Univ. Hawaii.
