| Outline of Final Research Achievements |
We investigated important processes in various stages of star formation, starting from the formation of molecular clouds from warm atomic medium, covering to the formation of protostars and protoplanetary disks. Based on those result we proposed an integrated scenario of star formation processes in our galaxy, which explains most of important observational aspects, such as cloud-to-cloud velocity dispersion, and the mass function of molecular cloud cores, star formation efficiency, and gas depletion timescale. We also investigated two kinds of new planet formation scenario: one is hybrid model that combine gravitational instability and core-accretion model. The other is based on secular gravitational instability. Our paper on the latter process resulted in the prediction of multiple ring-like structure in the protoplanetary disks prior to the discovery of multiple ring structure in HL-Tau disk by ALMA. This process is supposed to be important in creating so-called debris disks.
