Outline of Final Research Achievements |
Stars are the important constitute of the Universe and play a role in the dynamical and chemical evolution of the Universe. Recent ALMA observations are unveiling the vary early phase of the star formation. Using numerical simulations, this study investigates the the star formation process in molecular cloud cores which are parent of stars. In addition, comparing observations with simulation results, the formation process of circumstellar disks and driving mechanism of outflow and jet are clarified. Finally, a new formation scenario of star is constructed.
