在介质中漂移：在吸积盘和其它环境中双星的反冲和自推进
Drifting through the medium: kicks and self-propulsion of binaries within accretion disks and other environments
摘要：
致密双星是引力波和电磁波探测器可以探测到的，对于我们理解天体物理环境和致密天体的组成是很重要的。有大量的工作致力于这种双星在背景介质中的演化，例如在共同包络演化、吸积盘和暗物质迷你尖峰中。在这里，我们将进一步探索在环境中演化的引力约束二进制文件。我们表明，耗散效应，如引力拖曳和吸积赋予的质心的非对称双星的动量。我们在数值上发展的二进制文件在牛顿设置和显示，根据介质密度，质心可以加速到高速度-在某些情况下$300\, {\rm km/s}$或更多-在inspiral，与潜在的可观察到的签名。我们的数值结果是完全一致的\textit{analytical}的结果CM的发展在一阶介质密度。
英文摘要：
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.
