| Outline of Final Research Achievements |
I studied about the formation and evolution of general terrestrial planets. (1)
I discussed the conditions that terrestrial planets must satisfy for an internal ocean to exist on the timescale of planetary evolution. (2) I proposed a new scenario that protoplanetary fragments produced by the giant impacts might affect the evolution of the early Earth dynamically and chemically. (3) I showed the existence of Earth-sized moons around extrasolar gas giants and discussed the habitability of the moons.
