行星形成数值模拟的研究现状与未来需求II:行星迁移、核吸积以及大气逃逸
The Current Status and Future Perspectives on Numerical Simulations of Planet Formation II:Planet Migrations, Core Accretion, and Atmosphere Escape
摘要
Abstract
This paper review our current understandings in some important stages of planet formation, including planet migration, core accretion, and atmospheric escape. Planet-disk interaction leads to planet migration, which can significantly influence the planet’s orbital properties as well as the disk structure. The core accretion process largely determines the destiny of growing planet embryos: to become a gas giant or a terrestrial planets. The process of atmospheric escape is strongly connected to the planetary climate and potentially origin of life. All these stages involve complex radiative magnetohydrodynamic (MHD) processes. With growing computational power and the advance of numerical algorithms, we now in an era of using computational methods to solve highly nonlinear dynamical problems, alleviating the limitation of earlier times. While computational MHD is towards its maturity, efforts that aim to incorporate radiative transfer into MHD processes are still in its infancy. This paper stresses the necessity of radiation MHD studies in the field of planet formation. We also describe the scientific demand on the capability of radiation MHD codes, and strategies for developing radiation MHD codes in China for planet formation applications.关键词
