【摘要】:行星在氣態(tài)的原行星盤中形成,而行星形成的全過程幾乎都與原行星盤中氣體與塵埃的動力學(xué)密不可分。原行星盤中氣體與塵埃的動力學(xué)過程涉及包括非理想磁流體、化學(xué)、熱輻射、非熱輻射、空氣阻力等諸多效應(yīng)的作用以及它們之間的相互耦合,因而關(guān)于行星形成問題的研究往往需要進(jìn)行數(shù)值模擬,并對計(jì)算工具有著很高的要求。對研究行星形成問題所涉及的物理過程進(jìn)行概述,簡要介紹這些研究中主要使用的數(shù)值方法/算法,以及國際上與之相關(guān)的最新進(jìn)展。最后,對未來行星形成領(lǐng)域的發(fā)展及其對數(shù)值工具的需求作以展望。
[Abstract]:Planets are formed in gaseous protoplanetary disks, and the whole process of planetary formation is almost inextricably related to the dynamics of gas and dust in the original planetary disks. The kinetic processes of gas and dust in the original planetary disk are related to the effects of non-ideal magnetic fluid, chemistry, thermal radiation, non-thermal radiation, air resistance, and their mutual coupling. Therefore, the study of planetary formation problem often needs numerical simulation, and has high requirements for computing tools. This paper summarizes the physical processes involved in the study of planetary formation, briefly introduces the numerical methods / algorithms mainly used in these studies, and the latest developments related to them in the world. Finally, the future development of planetary formation and its demand for numerical tools are prospected.
