Outline of Final Research Achievements

To explore the nature of first generation stars and early chemical evolution, which are key to understanding the structure formation and evolution of matter in the universe, we conducted a large spectroscopic survey of metal-poor stars with LAMOST in China and the Subaru Telescope, along with construction of a database of stellar chemical abundances as well as theoretical studies of supernovae, stellar evolution and dust formation. The results of these studies indicate that (1) a majority of first stars should have been massive stars having typical mass of around 13-40 solar masses, (2) low-mass stars are few, if any, among first stars, and (3) dust is formed in the environment of very low-metallicity and affects the star formation process. We also obtained a strong evidence for accretion of a small stellar system like dwarf galaxies into the Milky Way after it experienced chemical evolution.

Academic Significance and Societal Importance of the Research Achievements

私たちを形づくる物質、そして地球を含むあらゆる天体が宇宙のなかでどのように作り出されてきたのか--これは人類共通の疑問と言っても過言ではない。宇宙の初期に誕生し、現在でも太陽系の近くに生き残っている星を調べることにより、宇宙の最初に生まれた星は超新星爆発を起こす大質量星であったこと、星や超新星が作り出した多様な元素やダストが後の世代の星形成につながっていったことを様々な角度から調べ、明らかにした。
