论文摘要
星系中暗物质（DM）的分布不均匀。在中央区域附近，其密度最高。然后，逻辑假设在星系内DM在中央区域比外部区域更大的恒星物理。此外，当前的恒星进化模型在其假设中没有考虑DM效应。要考虑DM效应，首先必须估计恒星所含的DM。文献中已经研究了单个恒星对DM颗粒的捕获率（Cr）。在这项工作中，我们讨论当恒星是二进制恒星系统（BSS）的成员时（而不是单独研究它们）时，如何影响CR。当恒星是BSS的成员时，由于其伴侣恒星周围的椭圆运动，其速度会定期变化。在这项工作中，我们在不同的BSS配置中调查了BSS的CR。最后，我们讨论了可以归因于BSS中DM效应的观察性特征。
The distribution of dark matter (DM) inside galaxies is not uniform. Near the central regions, its density is the highest. Then, it is logical to suppose that, inside galaxies, DM affects the physics of stars in central regions more than outer regions. Besides, current stellar evolutionary models did not consider DM effects in their assumptions. To consider the DM effects, at first one must estimate how much DM a star contains. The capture rate (CR) of DM particles by individual stars was investigated already in the literature. In this work, we discuss how CR can be affected when stars are members of binary star systems (BSS) (instead of studying them individually). When a star is a member of a BSS, its speed changes periodically due to the elliptical motion around its companion star. In this work, we investigated CR by BSSs in different BSS configurations. In the end, we discussed observational signatures that can be attributed to the DM effects in BSSs.
