Terrestrial planet formation including impact process

我们制作了包含原行星轨道演化和撞击过程的混合代码。这两个过程是行星形成的基础。利用这个巨碰撞阶段的混合代码，系统地研究了类地行星的形成，并推导出了类地行星的最终数量、质量、自旋态等重要静力学。根据这些结果，我们讨论了类地行星的普遍性和特殊性。

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.
