Outline of Final Research Achievements

It is one of the most important topics of current astrophysics to clarify the nature of the First Stars in the Universe, i.e., their masses, evolution, explosion and nucleosynthesis. In the present study, we have focused on the nature of superluminous supernovae, i.e., their progenitors, explosion mechanisms, and a possible connection to First Stars. In particular, we have calculated the light curves of three promising models: circumstellar interaction models, magnetar models, and 56Ni decay models. By comparing with the observed light curves of superluminous supernovae, we conclude that circumstellar interaction models are best compatible with observations. We then suggest First Stars would be as massive as 100 solar mass and may form relatively massive black holes.

Academic Significance and Societal Importance of the Research Achievements

我々の宇宙がどのように誕生し進化してきたかを明らかにすることは、我々自身の起源、将来を解明する上で、学術的にも社会的にも最も重要な課題の一つである。多くの証拠が宇宙がビッグバンとして始まったことを示しているが、ビッグバン後にどのような初代星が形成されたかは明らかになっていない。本研究では最近発見された超高輝度超新星が太陽質量の100倍近い星の爆発であることを明らかにし、初代星の有力候補であること示した。
