超大质量黑洞周围的动力学

Dynamics around supermassive black holes

Alessia Gualandris, David Merritt

摘要:

星系核的动力学在许多方面反映了超大质量黑洞的存在。单个SBH充当汇,在大约一个弛豫时间内摧毁恒星中等于其自身质量的质量,并迫使核膨胀。双星SBH的形成使恒星中的质量大致等于双星的质量,产生低密度的核心并喷射出超高速恒星。引力辐射反冲可以从原子核中喷射出聚结的二元SBH,导致偏移的SBH和不平衡的核心。我们回顾最近的工作,这些机制,并讨论了可观察到的后果。

英文摘要:

The dynamics of galactic nuclei reflects the presence of supermassive black holes (SBHs) in many ways. Single SBHs act as sinks, destroying a mass in stars equal to their own mass in roughly one relaxation time and forcing nuclei to expand. Formation of binary SBHs displaces a mass in stars roughly equal to the binary mass, creating low-density cores and ejecting hyper-velocity stars. Gravitational radiation recoil can eject coalescing binary SBHs from nuclei, resulting in offset SBHs and lopsided cores. We review recent work on these mechanisms and discuss the observable consequences.
