Outline of Research at the Start

星形成がどのように始動するかは、わかっていない。安定な星なしコアが、不安定になって星形成を開始するメカニズムとしては、乱流の散逸、磁場の散逸、質量の降着、コアの振動によるエネルギー散逸、などの可能性が指摘されているが、どれが正しいかは、まだ不明である。星形成に至るコアのサンプルを集め、その進化を追うことが喫緊の課題である。角運動量は、連星系誕生の頻度、惑星の誕生の仕方を決める重要な物理パラメーターである。周知のように恒星の半分以上は連星であり、また、惑星系の誕生の仕方は生命居住可能(ハビタブル)惑星との関連で重要である。分子雲コアの年代測定を基に、比角運動量の進化(減少の様子)を研究する。

Outline of Final Research Achievements

The starting mechanism of star (stellar) formation remains an unresolved issue. In this study, we conducted research using a new method we have developed, which dates "molecular cloud cores" the material from which stars are formed, by measuring deuterium fraction of deuterated molecules they contain. We cataloged cores that are just before or just after the onset of star formation. To carry out this research, we developed a new receiver named 7BEE and installed it on the Nobeyama 45 m radio telescope. With this receiver, the 45 m telescope became the world's fastest single-dish radio telescope (comprising a single parabolic antenna) capable of creating deuterium maps. We successfully obtained an unprecedentedly wide-area deuterium map in Orion. Through research using both the 45 m radio telescope and the ALMA telescope, we found that mass accretion is a strong candidate mechanism driving the onset of star formation.

Academic Significance and Societal Importance of the Research Achievements

分子雲コアは、多数観測されていることから、力学的に安定と考えられる。安定なままでは、星は誕生しないので、何らかのメカニズムにより不安定になると考えられる。人間の寿命よりはるかに長い分子雲コアの進化を、その成分である分子の重水素の割合を用いて年代測定する新手法を確立することにより、はじめて星形成の直前直後のコアをカタログ出来るようになったことは画期的である。また、星形成の始動メカニズムとして、乱流の散逸、質量降着、磁場の散逸、などが候補として考えられてきたが、新手法により、質量降着が有力であることを特定できたことは重要である。
