行星形成理论模型及行星分类 postprint

Abstract: Classification is a commonly used method in astronomy, which has been widely used in the research of stars and galaxies, but currently there is no complete classification system in the planetary field. This paper reviews the construction process of the theoretical model of planet formation and its shortcomings; Summarizes the search results of exoplanets and their parameter distribution characteristics; Introduces the current research background, progress and limitations in planet classification; In order to cover more exoplanet popula#2;tions, it is proposed to combine radio observations on the protoplanetary disks, and expand the sample of theoretical research and classification framework; Finally, the paper describes the observation capabilities and scientific goals of the latest generation and planning large observation equipment in terms of exoplanets.
