论文摘要
黑洞(BH)热力学是BH物理学最迷人的方面之一。尽管其直接证明是为了观察天体物理BHS的挑战,但重力波(GWS)最近提供了一种新的间接方法,以探测其在宇宙中的运行。在本文中,我们讨论了IMBH的热力学稳定性,这些稳定性通过恒星质量BHS的反复合并通过密集的星形簇中的GW发射而诞生。我们表明,通过重复合并出生的IMBH的$ \ lyssim 20 \%$对于非电荷BH的热力学不稳定,而$ \ lyssim 40 \%\%$ $对于中度收费的BH是热力学上不稳定的。仅在不太可能高电荷的情况下,$ \ gtrsim 60 \%的IMBHS在热力学上是稳定的。随着目前和即将到来的GW任务,例如Ligo/Wigo/Kagra,Lisa,Decigo和ET,他们承诺通过GW发射在未来十年内通过GW发射来检测IMBH的IMBH合并,IMBH热力学可能很快就会被测试。
Black hole (BH) thermodynamics is one of the most fascinating aspects of BH physics. While its direct proof is challenging to observe for astrophysical BHs, gravitational waves (GWs) have recently offered a new indirect powerful method to probe that it is operating in the Universe. In this paper, we discuss the thermodynamic stability of IMBHs that are born through repeated mergers of stellar-mass BHs via GW emission in dense star clusters. We show that $\lesssim 20\%$ of the IMBHs born via repeated mergers are thermodynamically unstable for a non-charged BH, while $\lesssim 40\%$ are thermodynamically unstable for a moderately-charged BH. Only in the case of unlikely high charges, $\gtrsim 60\%$ of the IMBHs are thermodynamically stable. With the present and upcoming GW missions, such as LIGO/Virgo/KAGRA, LISA, DECIGO, and ET that promise to detect tens, or even hundreds, of IMBH mergers via GW emission in the next decade, IMBH thermodynamics may soon be tested.
