摘要：
我们将中子星-黑洞（NS-BH）并合候选体作为致密奇异天体的检验对象展开研究。利用LIGO-Virgo合作组探测到的GW190814、GW200105和GW200115事件（这些事件覆盖了中子星质谱中较宽的质量范围），我们论证了未来观测对暗物质构成的致密星参数空间的约束能力。我们考虑了三类暗物质星的可能情形：自相互作用的纯玻色子或纯费米子暗物质星、由相互作用的玻色子与费米子物质混合构成的恒星，以及自束缚星的极限情形。我们发现这些假想天体的尺度由强相互作用的尺度主导。费米子暗物质的存在要求暗物质粒子处于GeV质量标度，而玻色子暗物质粒子的质量可大可小，没有限制。在自束缚线性物态方程的极限情形下，我们发现这些构型的真空能必须与量子色动力学（QCD）的真空能相近。
英文摘要：
We investigate neutron star-black hole (NS-BH) merger candidates as a test for compact exotic objects. Using the events GW190814, GW200105 and GW200115 measured by the LIGO-Virgo collabration, which represent a broad profile of the masses in the NS mass spectrum, we demonstrate the constraining power for the parameter spaces of compact stars consisting of dark matter for future measurements. We consider three possible cases of dark matter stars: self-interacting, purely bosonic or fermionic dark matter stars, stars consisting of a mixture of interacting bosonic and fermionic matter, as well as the limiting case of selfbound stars. We find that the scale of those hypothetical objects are dominated by the one of the strong interaction. The presence of fermionic dark matter requires a dark matter particle of the GeV mass scale, while the bosonic dark matter particle mass can be arbitrarily large or small. In the limiting case of a selfbound linear equation of state, we find that the vacuum energy of those configurations has to be similar to the one of QCD.
