恒星形成的辐射流体（磁流体）数值模拟研究进展

摘要

Stars are one of the most important objects in the universe and study of star formation is an important research subject. Astronomers are trying to understand a series of problems associated with star formation, which include how massive stars and star cluster form, what processes determines the physical properties of star-forming region, what deter-mines the initial mass function, what determines the star formation rate, and so on. Recently, numerical simulations of star formation continues to make progress. This paper focuses on research progress in the numerical study of protostellar collapse, massive star formation, frag-mentation and collapse of molecular cloud, star cluster formation and the initial mass function, based on radiation hydrodynamics (magnetohydrodynamics).%恒星是宇宙中最重要的天体之一，恒星形成是天体物理学研究的重要课题。天文学家正致力于理解与恒星形成相关的一系列问题，如：大质量恒星和星团是如何形成的？什么样的物理过程决定了恒星形成区域的物理性质？初始质量函数由什么确定？恒星形成率由什么决定？近年来，恒星形成的数值模拟研究不断发展。主要介绍了辐射流体(磁流体)的数值研究在原恒星核坍缩、大质量恒星形成、星云破碎和坍缩、星团形成和初始质量函数等方面的模拟研究进展。
