疏散星团的近期研究进展(Ⅱ):动力学和形成过程

Recent Developments on Studies of Open Clusters (Ⅱ):Dynamics and Formation Process

疏散星团动力学及形成过程的研究对于恒星动力学理论和银河系恒星形成理论具有重要意义。虽然疏散星团动力学问题还没有得到完全解决,但是通过理论(特别是N体模拟)和实际观测的结合研究,对于疏散星团的结构、内部运动和动力学演化已有了相当程度的认识和了解。有关疏散星团形成过程的研究理论和观测也都在进展之中。本文试就疏散星团动力学和形成过程的近期研究情况作一简要的介绍与评述。

Studies of the dynamics and formation process of open clusters are of great significance for stellar dynamics and star formation in the Galaxy. The dynamics of open clusters is a problem which has not been solved completely. However, by combination of theoretical work, especially N-body simulations, and observational examination, a very good knowledge of the structure, internal kinematics, and dynamical evolution of open clusters has been obtained. Research of the formation process of open clusters is also in progress recently both theoretically and observationally. In this paper, developments on studies of the dynamics and formation process of open clusters are briefly described and reviewed.
