Outline of Final Research Achievements

NAOJ's 188cm reflector telescope was successfully renovated into an autonomous robotic telescope, which allowed us to continue our large-scale exoplanet search in G-type giant stars for five years. As a result, while 24 planetary mass candidates and 6 brown dwarf mass sources had been detected by the time of this research application, 15 new planetary mass candidates were added by the end of this research. No new brown dwarf mass candidates were added. In total, we reached 39 planetary mass candidates and 6 brown dwarf mass candidates.

Academic Significance and Societal Importance of the Research Achievements

独自のロボット望遠鏡システムを開発することで巨星における太陽系外惑星の探索を大規模に進め、世界的に見ても有意な数の惑星質量候補天体の検出を達成した。系外惑星の存在そのものやその一般性や特殊性を明らかにすることで、宇宙や宇宙の中の地球の存在というものについて身近に感じ考える機会を社会に提供した。
