Outline of Annual Research Achievements

本研究では、観測好適地に位置する南アフリカ天文台の望遠鏡に赤外線分光観測装置を製作し、若い恒星まわりの初めての大規模惑星探索を行う。さらに、すばる望遠鏡なども利用しつつ太陽近傍の赤色矮星まわりのハビタブル惑星も探索する。これらにより、惑星探索を中心としたアストロバイオロジーも展開する。今年度は南アフリカ天文台に観測設備を準備する事業を継続した。大阪大学の口径1.8m望遠鏡PRIMEと名古屋大学等の口径1.4m望遠鏡IRSFに搭載可能な高分散分光器の詳細な設計を行った。今年度は、さらに南アフリカ天文台の口径11m望遠鏡SALTにファイバーでリンクすることも検討に加えた。赤外線視線速度装置の仕様は以下のように変更した。zおよびYバンドを同時にカバーし、波長分解能最大55,000を達成する。波長校正にはファブリペローフィルターを用いる。分光光学系内でイメージスライサーを用いて像を２分割し高い波長分解能を確保する。分光器へは光ファイバーを使用して望遠鏡からの光を伝送する。天体光と波長校正用光源をそれぞれ別のファイバーに入射させ、分光器焦点では隣接した位置にスペクトルが結像されるような光学系とする。熱背景雑音を減らし高い感度を達成するために、光学定盤温度は180K、カメラレンズ・検出器温度は80Kとする。赤外線検出器としてテレダイン社の2048x2048素子HgCdTeを購入した。特徴は望遠鏡を含めた効率が20%と高いことである。これと並行して、IRSF望遠鏡のリモート観測化のための制御系の更新も継続した。さらに、PRIME望遠鏡の主焦点、IRSF望遠鏡のカセグレン焦点でのファイバーの導入についての検討を進めた。また、若い惑星およびM型星まわりの惑星の短期観測結果を出版し、関連する系外惑星・星惑星形成の研究成果も多数出版した。

Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

開発中の赤外線分光器の詳細設計は順調である。また、その開発に専念する研究員および既存の装置を利用しつつ観測を推進する研究員も確保しており、開発と研究の両面での活動度も向上している。さらに、すばる望遠鏡における高精度赤外線分光器IRDによるM型星まわりの惑星探査を戦略枠観測として開始し、また、若い惑星の短期探査も共同利用観測で推進し、これらの初期成果を査読論文として出版した。さらに、本研究に密接に関係する若い惑星と軽い惑星を含む多数の系外惑星のトランジット法による検出をTESS望遠鏡等を利用して行い、多数の査読論文として出版した。当初予期していない問題は発生していない。

Strategy for Future Research Activity

南アフリカ天文台用の分光器の製作を継続する。購入した赤外線検出器H2RGのための読出装置の最適化を進める。分光器は大阪大学の口径1.8m望遠鏡PRIMEのサイトに設置し、当望遠鏡、名古屋大学等の口径1.4m望遠鏡IRSF、さらに南アフリカ天文台の口径11m望遠鏡SALTにファイバーでリンクする。zおよびYバンド(0.83-1.33um)を同時にカバーし、波長分解能最大55,000を達成する。熱背景雑音を減らし高い感度を達成するために、光学定盤温度は180K、カメラレンズ・検出器温度は80Kとする。この光学系・検出器系をインストールするために温度安定化された真空低温チャンバーを製作する。コストを低減するために波長校正にはファブリペローフィルターを採用する。分光光学系内でイメージスライサーを用いる。分光器へは光ファイバーを使用して望遠鏡からの光を伝送する。天体光と波長校正用光源をそれぞれ別のファイバーに入射させ、分光器焦点では隣接した位置にスペクトルが結像されるような光学系とする。赤外線検出器としてテレダイン社の2048x2048素子HgCdTeを使用している。本装置の特徴は望遠鏡を含めた効率が20%と高いことである。これと並行して、IRSF望遠鏡のリモート観測化のための制御系の更新も継続する。また、すばる望遠鏡、TESS望遠鏡による若い惑星およびM型星まわりの惑星探査などの各種の観測も多面的に推進する。
