摘要

本文综述了有关双星月食系统中附位运动问题的研究工作。结果表明，最近的主序星理论模型与观测到的附侧运动速度基本一致。然而，I-III型恒星的中心凝结比理论模型预测的要多。结果表明，观测到的恒星光球旋转速率较差地反映了大部分恒星质量(核心)的实际轴向旋转速率，而EBS组成部分的核心平均旋转速度比它们的光球要快。

Apsidal motion in eclipsing binary systems

A review of work devoted to the problem of apsidal motion in eclipsing binary systems (EBSs) is given. It is shown that recent theoretical models for stars in the main sequence in general are in agreement with the observed apsidal motion velocities. However, the stars of types I–III show more central condensation than predicted by the theoretical models. It is revealed that the observed rates of the stellar photospheric rotation poorly reflect the real rates of axial rotation of greater part of stellar mass (core) and that cores of components of the EBS rotate, on average, more rapidly than their photospheres.
