Terrestrial planet formation including impact process

我们编制了包括原行星轨道演化和碰撞过程的混合程序。这两个过程是行星形成的基础。使用巨型撞击阶段的混合程序，我们系统地研究了类地行星的形成，并导出了重要的静力学数据，如类地行星的最终数量、它们的质量、自旋态等。根据这些结果，我们讨论了类地行星的共性和特殊性。

We have made the hybrid code including both the orbital evolution and impact process of the protoplanets. Such two processes are fundamental to the planet formation. Using this hybrid code for the giant impact stage, we systematically investigate the terrestrial planet formation, and derive the important statics such as the final number of the terrestrial planets, their mass, spin states, and so on. From these outcomes, we discuss the generality and specificity of the terrestrial planets.
