恒星形成定律的研究现状OA北大核心CSTPCD

The physical environment of molecular clouds has an important impact on the star formation rate,and understanding star formation is of great help to the formation of planets and the evolution of galaxies.This paper mainly reviews the relationship between star formation and gas in the Milky Way and the other galaxies in the past decade(that is,star formation law).Methods of measuring gas contents and star formation rates are also discussed.In order to understand the nature of star formation,whether there is any necessary connection between star formation and gas,and whether stars are forming in a unified way,this article focuses on the relationship between dense gas and star formation rate from the galactic level to the individual molecular cloud level.At the same time,the composition of the interstellar medium and the method of measuring the density and star formation rate of the interstellar medium are also introduced.
