Outline of Final Research Achievements

We have carried out an international project, ALMA-IMF, to understand the precursor of the initial mass function (IMF). The IMF is a universal function that describes the initial distribution of masses for a population of stars. It is generally accepted that the precursor of the IMF is consistent with the universal IMF in regions forming stars like our Sun. However, current observational evidence suggest that in regions forming massive stars (with masses 8 times larger than the Sun), the precursor of the IMF is different. We have observed 15 high-mass star-forming regions with ALMA and find that the precursor of the IMF is different. We also find that the precursor of the IMF also evolves over time, resembling the IMF only at late stages of evolution.

Academic Significance and Societal Importance of the Research Achievements

星の質量は、星の進化を決定する重要な物理量です。星の質量はその母体となる高密度コアの質量と関係している ことが知られています。太陽系の誕生過程や進化を理解する上で、星の質量と高密度コアの質量との関係を 明らかにすることは非常に重要です。星の質量は生命誕生の条件とも関係しています。
本研究から、我々は、星を形成する構造の質量分布が小質量星のみが形成される領域と大質量星も形成される領域で 異なることを発見しました。大質量星は銀河におけるエネルギー流入を支配しており、この発見により近傍や遠方の宇宙の形成や進化についての理解が深まると期待されます。
