中文简介:
本课程涵盖了对行星形成的知识状态的考察,从行星星云开始,并通过吸积(从气体,到尘埃,到星子,到行星胚胎,到行星)继续。它还包括行星分化、地壳形成、大气脱气和地表水凝结的过程。本课程以太阳系及系外行星的观测为基础,整合了组成与物理过程的讨论。集中在陆地(岩石和金属)行星,虽然更多的挥发性丰富的物体也被检查。
课程简介: This course covers examination of the state of knowledge of planetary formation, beginning with planetary nebulas and continuing through accretion (from gas, to dust, to planetesimals, to planetary embryos, to planets). It also includes processes of planetary differentiation, crust formation, atmospheric degassing, and surface water condensation. This course has integrated discussions of compositional and physical processes, based upon observations from our solar system and from exoplanets. Focus on terrestrial (rocky and metallic) planets, though more volatile-rich bodies are also examined.
