| Outline of Final Research Achievements |
In this study, we aimed to investigate the nature of super-Earths, which are emerging population of extrasolar planets. To do so, we have worked on development of a new astronomical instrument named MuSCAT (Multi-color Simultaneous Camera for studying Atmospheres of Transiting exoplanets), which is a 3-color simultaneous camera, for the 188cm telescope at Okayama Astrophysical Observatory. Using the instrument and other facilities, we conducted observations and theoretical modeling to reveal properties of super-Earths.
Consequently, we succeeded in developing MuSCAT faster than we expected, and discovered 2 new super-Earths based on our observations using MuSCAT. We also succeeded in detecting a planetary transit of the habitable super-Earth K2-3d using MuSCAT for the first time from the ground, and improved the knowledge about properties of this planet.
Based on the above and other publication results, we have made better-than-expected achievements from this study.
