中子星中致密暗天体的引力波

Gravitational Waves from Compact Dark Objects in Neutron Stars

C. J. Horowitz, Sanjay Reddy

摘要:

暗物质可能由致密暗天体(CDO)组成。我们发现中子星内部CDO的振荡可以成为一个可探测的引力波源。GW应变振幅取决于CDO的质量,其频率通常在3-5 kHz的范围内,由恒星的中心密度决定。在最好的情况下,LIGO可能对质量大于或等于$10^{-8}$太阳质量的CDO敏感。

英文摘要:

Dark matter could be composed of compact dark objects (CDOs). We find that the oscillation of CDOs inside neutron stars can be a detectable source of gravitational waves (GWs). The GW strain amplitude depends on the mass of the CDO, and its frequency is typically in the range 3-5 kHz as determined by the central density of the star. In the best cases, LIGO may be sensitive to CDO masses greater than or of order $10^{-8}$ solar masses.
