Outline of Research at the Start

銀河系の星の元素組成・動力学的性質には銀河系が辿ってきた過去の情報が刻まれている。本研究では、ユーロピウムなどのrプロセス元素に着目した銀河形成シミュレーションを実施し、銀河の形成進化史と星のrプロセス元素組成を対応させる。位置天文衛星Gaiaと高分散分光観測による星の元素組成・動力学的性質から銀河系の形成進化史を再構築する。これにより、星のrプロセス元素組成を銀河進化の指標として確立することを目指す。

Outline of Final Research Achievements

This project clarified the formation environments of stars enhanced in the elements heavier than iron (r-process elements) in the Milky Way with high-resolution galaxy formation simulations. Firstly, we developed a new star formation model and realized galaxy and star cluster formation simulations, which can resolve individual stars. We then performed a Milky Way formation simulation and showed that most r-process enhanced stars were formed in dwarf galaxies accreted later to the Milky Way in the early Universe.

Academic Significance and Societal Importance of the Research Achievements

本研究で実現した個々の星を分解した銀河形成シミュレーションにより、銀河形成の観点から個々の星の運動、元素放出を追えるようになった。これにより、観測された星の元素組成からその星が形成された環境が理解できるようになる。さらに、rプロセス元素に富んだ星の形成環境を明らかにしたことで、rプロセス元素に富んだ星の元素組成、動力学的性質から、天の川銀河の宇宙初期での形成史を辿れる可能性が示唆された。
