| Research Abstract |
The discovered extrasolar planets have strange orbits. We investigated the formation of close-in planets and distant planets through N-body simulations of gas giant planets. We found that the close-in planets and distant planets can be formed by the planet-planet scatterings. The close-in planets formed by scattering can have broad range of orbital inclinations as observations suggest.
