中文摘要
已发现的太阳系外行星具有奇怪的轨道。我们通过对气态巨行星的N体模拟,研究了近距离行星和远距离行星的形成。我们发现,近距离的行星和遥远的行星都可以由行星-行星的散射形成。正如观察所表明的那样,由散射形成的近距离行星可以有很大范围的轨道倾角。
英文摘要
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.
