| Outline of Final Research Achievements |
I studied about various physical processes of planet/satellite formation in the solar system, and proposed new scenarios about them. (1) I derived a new torque formula for planet migration by taking into account dynamic corrections, and showed that inward migration was slowed by the dynamic effects. (2) I proposed a new scenario that planetary impact processes would affect the evolution of the early Earth dynamically and geochemically. (3) I developed an N-body simulation code and execute extra-high-resolution N-body simulations of lunar accretion to show the results depended on the numerical simulation.
