论文摘要

Chandrasekhar质量限制(1.4 $ M _ {\ odot} $)下方的黑洞不能通过任何标准的恒星演变产生。最近,引力波实验还发现了异常低的质量黑洞,其起源尚不清楚。我们提出了一种如此低质量黑洞的简单而新颖的形成机制。由于它们与恒星核的相互作用,非渗透颗粒暗物质可以逐渐积聚在紧凑的恒星内,并最终将其吞入低质量黑洞,通常是由Chandrasekhar限制所无法提供的。我们指出了一些测试该提案的途径,重点关注二进制合并率的宇宙演变。

Black holes below Chandrasekhar mass limit (1.4 $M_{\odot}$) can not be produced via any standard stellar evolution. Recently, gravitational wave experiments have also discovered unusually low mass black holes whose origin is yet to be known. We propose a simple yet novel formation mechanism of such low mass black holes. Non-annihilating particle dark matter, owing to their interaction with stellar nuclei, can gradually accumulate inside compact stars, and eventually swallows them to low mass black holes, ordinarily impermissible by the Chandrasekhar limit. We point out several avenues to test this proposal, concentrating on the cosmic evolution of the binary merger rates.
