Outline of Annual Research Achievements

アルマ高解像度観測に関連して，周惑星円盤の兆候とみられる構造が付随するTW Hya円盤の結果と理論計算との比較研究を推進し，複数の論文出版につなげた。また，ダスト連続波の多波長解析により円盤内でのダストサイズ分布を推定した結果，これまで得られていたダスト質量の見積もりに大きな不定性があることを明らかにした。さらにスパースモデリングによるイメージングにより，これまでよりも実質的な空間解像度が高いイメージを得られる可能性を，実際のデータに基づいて検証した。
円盤の水氷に関しては，3ミクロンの吸収線の性質について詳しい理論的な計算を行った結果，強度スペクトルに加えて偏光の情報を付加することで，ダストのサイズや水氷の存在量に制限をつけることに成功した。また，詳細な円盤化学モデルを通じてスノーライン内外での気相・固相中の元素組成比の半径分布のパラメータ依存性を調べ，ホットジュピター大気の組成分布に及ぼす影響を調べた。
円盤の統計的性質については，銀河系低金属量環境下に存在する星形成領域Sh 2-127の近赤外深撮像観測をすばる望遠鏡により行った。その結果，この領域中の原始惑星系円盤を持つ星の割合が太陽近傍の同年代のクラスターに比べて著しく低い一方，年齢が数十万年と非常に若いクラスターでは比較的高い付随割合が見積もられた。これらは低金属量環境下において，非常に若い段階では大部分の星が円盤を持つものの非常に短いタイムスケールで消失することを示唆する初めての結果である。またTESS データの解析から，従来知られていた星形成領域から離れた場所に，円盤を伴う若い星が複数存在している可能性を示した。せいめい3.8m望遠鏡用の新装置開発では，ダイクロイックフィルター2枚を設計製作し，その波長特性を確認し，前年度製作の反射光学系とともに装置への組込試験をした。

Current Status of Research Progress

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

Reason

以下の通り，全ての研究テーマで概ね予定通りの進捗が得られた。
まず円盤の高解像度画像の解析では，観測データ解析で順調に研究成果を挙げただけでなく，新たな解析手法であるスパースモデリングの有効性の実証を論文として発表した。これは，既存のデータからこれまでの解析手法以上に小スケールな構造を抽出できる可能性を広げ，再解析を通じてより大きなサンプルに基づく統計的議論を可能にするものである。
水に関しては，まず中間赤外線での水氷散乱光について，その波長依存性も含め自然な解釈を与えるダスト光学モデルを初めて構築した。また水蒸気に対するALMA観測は新型コロナウィルス流行のためオペレーションが休止したことに伴い停滞したものの，赤外線天文衛星計画SPICA，及び東大アタカマ天文台TAOによる水氷科学観測について，さまざまな検討を行った成果を発表した。これらはそれぞれ，グループ内で自ら得た研究成果に基づき，水氷による赤外線散乱過程や水蒸気放射過程を理論的に再検討することで得られたものであり，本研究課題の枠組みである理論と観測の親密な連携があって初めて実現された独自性の高い成果である。惑星形成の環境依存性を議論する上で鍵を握る低金属量領域に関する研究についても，複数の論文成果が出版されたほか，JWSTの観測プロポーザルの準備においても順調な進捗が得られた。具体的には，星形成領域Sh 2-127における円盤存在頻度の研究や，ASTE望遠鏡で取得された炭素原子微細構造線データに基づく分子雲内部への紫外線浸透に関する議論をした成果が挙げられる。星団環境下での円盤存在の統計的議論を科学目標に据えた，せいめい望遠鏡の新装置についても，順調に主要部品の製造と組み込み試験が進み，ほぼ当初の計画通り装置の組み上げへと進む準備が整った。

Strategy for Future Research Activity

基本的には引き続き当初の予定通り研究を進めるが，一部，新型コロナウィルス感染症拡大の影響を緩和するための方策をとる。
まずALMAを用いた円盤観測では，感染症拡大に伴い観測オペレーションが停止したことの影響を踏まえ，アーカイブデータの解析に当初予定していた以上に重点をおく。このため，この研究を推進する人員として特任助教１名に加えさらに1名研究員を雇用し，データ解析から論文化を進める体制を強化する。また，電波干渉計イメージング過程において問題となるデコンボリューション法の信頼度を向上させる手法の開発を継続して進める。円盤の水に関するもののうち赤外線観測では，Subaru/IRCS熱赤外偏光機能を用いた近傍の原始惑星系円盤や星形成領域の散乱光観測を中心に研究を進め，成果を取りまとめる。また，ALMAによる水スノーライン観測では，特にFU Ori型天体の水のスノーラインのモデル構築と観測を継続して進め，スノーラインの時間進化が惑星形成に及ぼす影響を探る。このほか，近傍の残骸円盤に関する統計的研究を継続し，これまでにない大きなサンプルを扱うことでより広大なパラメータ空間での惑星存在頻度に関する手がかりを得る。
低金属量環境下の研究については，太陽近傍と大きく環境の異なる「銀河系最外縁部」に対し，前年度までに引き続き，ALMA やASTEといったサブミリ波望遠鏡を用いた観測を継続するとともに，すばる望遠鏡をはじめとする赤外線観測装置を用いた研究も継続する。また，せいめい3.8m望遠鏡用の新装置開発では，昨年度までにほぼ完成させた部品の組み上げを終了し，望遠鏡搭載試験まで到達することを目指す。研究代表者及び分担者に加え，研究協力者して特任助教1名，研究員2名(計3名)を雇用し，以上の研究を実施する。
