低质量相接双星的研究进展

The Research Progress of Low-Mass Contact Binary

密近双星的观测和理论研究是恒星物理研究中热点之一。解释低质量相接双星的观测是双星演化的难点。本文通过对低质量的相接双星的实测资料(光变曲线和物理参量)和理论模型进行综述,提出了该类双星研究中主要存在的问题,这对于丰富和完善双星演化理论具有重要意义。

The observational and theoretical researches of close binary are one of stellar physical research hotspots. It is the difficult problem of binary evolution to explain observational phenomena of low-mass contact binary. By summarizing observational materials（ from light curve and physical parameters） and theoretical model of low-mass contact binary, some main questions in this research field were presented, this work was important to improve binary evolution theory.
