To study the origin and evolution of planetary systems based on the
theoretical considerations and astronomical observations, for
constructing a new standard model, the"Kobe model" for the formation
of planetary systems.
To study the primitive bodies in the solar system based on planetary
exploration,
analysis of primordial material, and laboratory/computer simulations
of elementary processes in the early phase of planetary formation.
To study the processes to form the diversity of planets based on
theoretical/experimental studies on the earth as a planet, and a
comparative studies for planets.
