Outline of Annual Research Achievements

本研究では、高コントラスト赤外線装置を用いて、我々の太陽系の惑星に似た系外惑星を直接撮像すると共に、原始惑星系円盤の詳細構造を描き円盤から惑星が形成される過程を解明し、巨大惑星の多様性の起源とその形成を解明する。さらに、世界最高精度の赤外線ドップラー観測装置を開発し、ハビタブルな地球型系外惑星を検出する。そのために、波長校正、分散素子、赤外波面補償光学という赤外線新技術開発を推進する。これらの観測の結果を惑星形成理論と比較し、系外惑星の起源・形成を解明する。
今年度は、すばる戦略枠SEEDSプロジェクトを継続して推進した。過去5年間に大きなトラブルはなく、2015年1月に当初の観測予定のサーベイを完了した。その結果、年齢100万年程度の若い恒星HD100546を周回する惑星を直接撮像により確認し、出版した。この惑星系には星周円盤も存在し、渦巻腕構造も検出した。その他いくつかの恒星のまわりの伴星候補天体の検出に成功した。直接観測法で検出可能な惑星の統計を調べ、出版した。海外研究者と共に、すばる望遠鏡およびケック望遠鏡を用いたM型星まわりの惑星探査の結果とハッブル望遠鏡を用いた残骸円盤の詳細観測の結果を出版した。さらに、SEEDS観測の一環として、若い恒星であるOph IRS48のまわりの原始惑星系円盤の微細構造を直接撮像した。これらの円盤に関するレビュー論文や偏光観測のレビュー論文を出版した。
開発的研究としては、本研究で新規に開発中の超高精度赤外線高分散分光器IRDのほぼ全てのコンポーネントを揃え、アセンブルを進めた。検出器は4Kx4K素子の開発に遅れが生じたため2Kx2K素子を用いることにした。光周波数コムはファイバーの見直しにより短波長側を拡張し1-1.7ミクロンまでを一度にカバーし、より高精度を確保できるようになっただけでなく、分光器と組み合わせて使用するためのシステムとして完成させた。ファイバースクランブルの実験を進め、いくつかの最適な手法を選択した。これらのIRDの開発研究に関する結果を国内外の学会および国際研究会で報告した(招待講演を含む)。また、サイエンス班によるM型星のまわりの惑星の検討を理論・恒星・可視光観測研究者と共に継続した。さらに、高速補正による約2000素子相当の超補償光学系の精度向上のための観測も進めた。
