Research Abstract

More than 750 extrasolar planets have been discovered, as well as more than 2300 candidates by Kepler space telescope, which motivates statistical discussions of planets and planetary systems. Here we investigated dependence of planetary systems on metallicity of the host stars. N-body and fluid dynamical simulations for planet-planet scattering and collisions have been carried out. Combining these results, we also performed Monte Carlo simulations to find that in a metal-rich disk around a metal-rich star, multiple gas giants are formed and they undergo orbital stability to pump up orbital eccentricities. We also promoted radial velocity surveys and construct a transit follow-up network involving amateurs and students to study the problem both from theory and observation.
