论文摘要
在中子恒星中发出的引力波的检测 - 黑洞合并和相关的电磁对应物将提供有关恒星进化核物质和一般相对论的大量信息。尽管已经很好地确定了有关中子星的理论框架 - 隔离为孤立的黑洞二进制文件，但对于那些通过动力学相互作用形成的人来说，图片受到了限制。在这里，我们使用N体模拟表明，与孤立的合并，即更大的质量，较重的黑洞和没有相关的电磁对应物相比，球状和核簇中形成的合并可能显示出独特的标记。这些功能可以代表解释即将进行的观察的有用工具。在本地宇宙中，在Decihertz频带中敏感的探测器可以揭示从动力学合并发出的重力波，而发生在Andromeda和处女座群集的距离范围内的探测器则可以通过Lisa等低频检测器来访问。
The detection of gravitational waves emitted during a neutron star - black hole merger and the associated electromagnetic counterpart will provide a wealth of information about stellar evolution nuclear matter, and General Relativity. While the theoretical framework about neutron star - black hole binaries formed in isolation is well established, the picture is loosely constrained for those forming via dynamical interactions. Here, we use N-body simulations to show that mergers forming in globular and nuclear clusters could display distinctive marks compared to isolated mergers, namely larger masses, heavier black holes, and the tendency to have no associated electromagnetic counterpart. These features could represent a useful tool to interpreting forthcoming observations. In the Local Universe, gravitational waves emitted from dynamical mergers could be unravelled by detectors sensitive in the decihertz frequency band, while those occurring at the distance range of Andromeda and the Virgo Cluster could be accessible to lower-frequency detectors like LISA.
