摘要:

超辐射可能导致黑洞(BH)凝聚系统形成。我们全面研究了吸积对这种系统演化的效应,以及在存在多种超辐射模式的情况下,该系统所发出的引力波信号。假设黑洞质量和标量质量的乘积为小数,我们得到了所有重要量的解析近似,可以直接应用于现象学研究。此外,我们确认吸积可以显著增强引力波(GW)发射并减少其持续时间,并展示了GW拍频特征也相应被修改。

英文摘要:

Superradiance can lead to the formation of a black hole (BH) condensate system. We thoroughly investigate the accretion effect on the evolution of this system, and the gravitational wave signals it emits in the presence of multiple superradiance modes. Assuming the multiplication of the BH mass and scalar mass as a small number, we obtain the analytical approximations of all important quantities, which can be directly applied to phenomenological studies. In addition, we confirm that accretion could significantly enhance the gravitational wave (GW) emission and reduce its duration, and show that the GW beat signature is similarly modified.
