| Outline of Final Research Achievements |
Through theoretical studies using computer simulations, we clarified (1) the elementary processes of (1) planetesimal formation and (2) planet formation, and integrated them to study (3) the general planet formation theory and the origin of the solar system. (1) We have obtained the results: the construction of a model of dust growth and migration, the construction of a model of dust impact coalescence and destruction and pebble formation, and the comparison of the integrated model of dust, planetesimals, and pebbles with disk observations. (2) We also obtained results on the collision and destruction processes of planetesimals, the accretion from planetesimal rings, the accretion of planetesimals taking into account the migration of materials, the formation of gas planets, and the formation of close-in super-Earth systems. (iii) We developed a planet population synthesis model and a statistical planet formation model that incorporate the elementary processes we have elucidated.
