摘要
文章对密近双星的Roche势进行分析,并计算出3个内、外拉格朗日点及其相应的Roche势.根据Roche势对密近双星进行分类,这对于探寻3类密近双星的演化联系起重要作用.当子星充满内(或外)临界等势面必定会发生质量和角动量的转移或损失,从而引起质量和角动量在两子星间的重新分布并最终导致双星并合.Roche势的计算对于密近双星的观测、分析和研究具有重要意义.
Roche model for close binaries was analyzed in this paper.Three Lagrangian points and the corresponding Roche potentials were calculated.Based on the Roche potential,it is essential for the classification for close binaries to explore the evolution connection among three kinds of binary stars.When one component fills its inner（or outer） critical equi-potential surface,it will lead to mass and energy transfer or loss.The mass and angular momentum transfer and redistribution between both components will eventually cause the binary system to merge.Therefore,it is very important for observing,analyzing and investigating the close binaries to calculate the Roche potential.
