论文摘要
随着二元系统在星系内部移动，它们与暗物质光环相互作用。这种相互作用导致二元组件内的暗物质颗粒的积聚。暗物质颗粒的积聚增加了二元组分的质量，然后增加了系统的总质量。通过这种方式增加的质量会影响系统的其他物理参数，例如系统的轨道周期。在这项工作中，我们估计了由于内部暗物质颗粒的积聚，一些已知的紧凑型二元系统的周期变化。我们的结论是，对于具有质量范围内$ \ simeq 10 \：gev.c^{ - 2} $和暗物质密度和暗物质密度与太阳周围的暗物质密度一样高的wimp颗粒，由于暗物质颗粒的积聚而导致的周期变化，与该系统的层次波的变化相比，由于暗物质颗粒的积聚而变化可忽略不计。
As binary systems move inside galaxies, they interact with the dark matter halo. This interaction leads to the accretion of dark matter particles inside binary components. The accretion of dark matter particles increases the mass of the binary components and then, the total mass of the system. Increased mass by this way can affect other physical parameters of the systems, like orbital periods of the systems. In this work, we estimated the period change of some known compact binary systems due to the accretion of dark matter particles inside them. Our conclustion is that, for WIMP particles with masses in the range $\simeq 10 \: GeV.c^{-2}$ and dark matter density as high as the dark matter density around the sun, period change due to accretion of dark matter partices is negligible compared to the period change due to the emission of gravitaional waves from the systems.
