| Outline of Final Research Achievements |
Regarding formation of protostars and protoplanetary disks, we have constructed a new scenario that a disk is formed at the stage of a Jupiter-mass star and the disk fragment into clumps to fall onto the star. Regarding planetesimal formation, through analysis of simultaneous evolution of dust size, porosity and orbit, we found that icy planetesimals are successfully formed. Regarding comparison of theory with observed data, we performed Monte Carlo simulations to reproduce the orbital eccentricity distribution of exoplanets. Our study of planetary atmosphere acquired from the disk could explain diversity of bulk density of extrasolar super-Earths. We also proposed two theoretical models to explain the ring structure in the disks that were revealed by ALMA observations.
