Abstract

This paper presents detailed evolutionary models of low-mass binary systems (1.25 + 1 M?) with initial orbital periods of 10, 50 and 100 days and accretion efficiency of 10%, 20%, 50%, and a conservative assumption. All models are calculated with the MESA (Modules for Experiments in Stellar Astrophysics) evolutionary code. We show that such binary systems can evolve via a stable Case B mass transfer into long period helium white dwarf systems.

初始轨道周期和吸积效率对低质量双星演化的影响

本文给出了初始轨道周期分别为10、50和100天，吸积效率分别为10%、20%和50%的低质量双星系统(1.25 + 1 M?)的详细演化模型和一个保守假设。所有的模型都是用MESA(实验模块在恒星天体物理学)进化代码计算的。我们证明了这样的双星系统可以通过稳定的B型质量传递演变成长周期的氦白矮星系统。
