论文摘要
广泛研究了由紧凑型恒星捕获的行星质量的原始黑洞，以限制其暗物质的组成部分。这种捕获可能会导致灵感过程，并通过重力波信号检测到。在这封信中，我们通过考虑两种不同类型的紧凑型星，即奇怪的恒星和中子恒星来研究捕获后的灵感过程。动态方程是在数值上求解的，并计算了重力波发射。发现先进的Ligo可以检测到$ 10^{-5} $太阳质量原始黑洞的灵感，距离为10 kpc，而在Megaparsecs中甚至可以检测到Jovian Mass Case。有希望的是，下一代重力波检测器可以检测出$ 10^{ - 5} $太阳质量原始黑洞的案例，最高为$ {\ sim} 1 $ MPC，并且可以在数百megaparSecs中检测到Jovian Mass Cases。此外，Kilohertz引力波信号对奇怪的恒星和中子恒星显示出显着差异，这可能使其成为对状态密集物质方程的新颖探针。
Primordial black holes of planetary masses captured by compact stars are widely studied to constrain their composition fraction of dark matter. Such a capture may lead to an inspiral process and be detected through gravitational wave signals. In this Letter, we study the post-capture inspiral process by considering two different kinds of compact stars, i.e., strange stars and neutron stars. The dynamical equations are numerically solved and the gravitational wave emission is calculated. It is found that the Advanced LIGO can detect the inspiraling of a $10^{-5}$ solar mass primordial black hole at a distance of 10 kpc, while a Jovian-mass case can even be detected at megaparsecs. Promisingly, the next generation gravitational wave detectors can detect the cases of $10^{-5}$ solar mass primordial black holes up to ${\sim}1$ Mpc, and can detect Jovian-mass cases at several hundred megaparsecs. Moreover, the kilohertz gravitational wave signal shows significant differences for strange stars and neutron stars, potentially making it a novel probe to the dense matter equation of state.
