Outline of Final Research Achievements |
This project undertook the elucidation of the massive star formation process through both theoretical and observational approaches, achieving significant results over four years of extensive international collaboration. Firstly, a scenario for overcoming the major obstacle of massive star formation, “radiation feedback,” via disk accretion was proposed and empirically verified through observations. Additionally, it was clarified that the high-temperature environment of massive protostar disks promotes the coalescence and evaporation of silicate grains, establishing its value as a laboratory for astro-mineralogical research. Furthermore, the massive star formation process in low-metallicity environments was investigated through numerical simulations and survey observations, revealing the diversity of physical processes and chemical properties. These results represent a crucial step toward comprehensive understanding and future research directions.
