Outline of Annual Research Achievements |
星間水素の挙動を詳細に解析し、新たな星間物質像を構築し、銀河進化研究に新局面を拓く成果をあげた。主な観測・理論解析の成果は以下にまとめられる。 (1)星間水素原子は粒状に分布する低温相と広く分布する高温相とからなる。低温相は水素分子雲を形成し分子雲への転移を担う。 (2)水素分子の紫外線観測が不可能であるために、分子雲形成を直接観測することはできないが、理論モデルとの比較によって兆候を抑え、形成途上の星間雲を特定した。 (3)COとCI(中性炭素原子)の比較観測が中性水素全体の挙動の解明に有効であることを示した。 (4)水素を定量する新手法を開発し、精度良く水素原子柱密度を導出した。この際、γ線、ダスト放射との比較を併用し、ダストが水素ガス密度によって成長していることを見出した。 (5)(4)と並行して、星間雲中の重元素量の高精度定量を可能にし、銀河系をとりまく高中速度雲の多くが10%程度の低重元素を持つことを明らかにした。 (6)マゼラン雲、M33、アンテナ銀河等において、大規模星団形成が水素原子雲および分子雲同士の衝突によって形成されていることを発見した。 (7)銀河系内およびマゼラン雲の超新星残骸について星間水素の精密定量を行い、X線・ガンマ線放射の放射機構や、宇宙線加速についての知見を深めた。 (8)広域分子雲観測装置NASCOの開発を行い、所期の性能を実証して広域観測の基盤を確立した。
