Outline of Annual Research Achievements

すばる望遠鏡などに搭載した赤外線装置を用いた若い恒星まわりの惑星とM型星まわりの惑星の観測、および、南アフリカ天文台に赤外線観測設備を準備する事業を継続した。今年度はとりわけコロナ禍の影響を受けた赤外線分光器および搭載予定望遠鏡の総合調整を推進した。今年度の観測的成果としては、M型星まわりのハビタブルゾーンを通過するスーパーアース系外惑星の発見、地球サイズの系外惑星の発見、原始惑星系円盤に埋もれた原始惑星の発見、加速する恒星まわりの直接観測による褐色矮星の発見、ジェームズウェッブ宇宙望遠鏡による系外惑星の初めての中間赤外線直接撮像および分光、多数の浮遊惑星の分光による検証など、多岐にわたった。これらの研究は、M型星における光合成の蛍光の生物学的考察などアストロバイオロジー成果にも繋がった。分光器は、観測波長範囲としてzバンドおよびYバンド(0.84-1.09 micron)を同時にカバーし、波長分解能最60,000を達成している。分光器へは光ファイバーを使用してIRSF、PRIME、SALTの3つ望遠鏡からの光を伝送できる。PRIME望遠鏡の主焦点にファイバーを導くための入射モジュールを準備した。ファイバーの視野は約2.1秒角である。精密波長校正にはファブリペローフィルターを利用しており、波長校正精度は約3m/sとなる。コロナ禍の影響で南アフリカ現地での作業が遅れたが、IRSF望遠鏡のリモート観測化のための制御系の更新とPRIME望遠鏡の整備も完了した。今後は南アフリカ天文台における近距離の若い恒星約180個や近傍M型星約80個などの本格的サーベイ観測を進める。
