Outline of Final Research Achievements |
We developed "Filament Paradigm" for low-mass star formation in the Galactic Disk and explained the origin of the mass function and angular momentum distribution of molecular cloud cores. We proposed evolutionary scenario of "Hub-Filament Systems" that are expected to be essential sites of the formation of massive stars and star clusters in our Galaxy according to the survey data of Herschel Space Telescope. We also analyzed the galactic wind driven by cosmic rays and magnetic field and found that cosmic ray energy density on the order of 1eV/cc is a threshold for active wind. Thus, if the star formation rate is much larger than the current rate, the Galactic disk lose gaseous component, which act as a negative feedback mechanism and reduces the star formation rate. This may explain the currently observed level of star formation in the Galactic Disk.
