论文摘要
紧凑型二进制室在引力和电磁波检测器的范围内，对于我们对天体物理环境和紧凑物体的组成而言非常重要。在背景媒体中，有很多作品致力于此类二进制文件的演变，例如共同的Envelope Evolution，积聚磁盘和暗物质迷你尖峰。在这里，我们探索了在环境中进一步发展的重力结合的二进制文件。我们表明，耗散效应（例如重力阻力和积聚）赋予了不对称二进制质量中心的动量。我们从数值上进化了牛顿设置的二进制文件，并表明，根据中等密度，质量中心可以加速到高速 - 在某些情况下，$ 300 \，{\ rm km/s} $或更多 - 在灵感期间，具有可观察的签名。我们的数值结果与\ textIt {分析}的结果完全一致。
Compact binaries are within the reach of gravitational and electromagnetic wave detectors, and are important for our understanding of astrophysical environments and the composition of compact objects. There is a vast body of work devoted to the evolution of such binaries in background media, such as in common-envelope evolution, accretion disks and dark matter mini-spikes. Here, we explore further gravitationally-bound binaries evolving within an environment. We show that dissipative effects such as gravitational drag and accretion impart a momentum to the center of mass of asymmetric binaries. We numerically evolve the binaries in a Newtonian setup and show that, depending on the medium density, the center of mass can accelerate to high speeds -- in some cases $300\, {\rm km/s}$ or more -- during inspiral, with potentially observable signatures. Our numerical results are fully consistent with an \textit{analytical} result for the CM evolution at first order in the medium density.
