黑洞吸积盘中的磁连接和电流分布

Magnetic connection and current distribution in black hole accretion discs

Cheng-Xuan Zhao, Ding-Xiong Wang, Zhao-Ming Gan

摘要:

本文在广义相对论的框架下,基于克尔黑洞(BH)盘内部环形电流的连续分布,讨论了大尺度磁场的可能起源之一.结果表明,产生了四种类型的磁连接(MC)配置,即,BH与遥远天体物理载荷的MC(MCHL),BH与盘的MC(MCHD),俯冲区与盘的MC(MCPD)和内外盘区的MC(MCDD)。结果表明,Blandford-Znajek(BZ)工艺可以被视为MC的一种类型,即,MCHL。此外,我们提出了一个方案,拟周期振荡的BH双星的基础上与磁重联相关的MCDD。

英文摘要:

We discuss one of the possible origins of large-scale magnetic fields based on a continuous distribution of toroidal electric current flowing in the inner region of the disc around a Kerr black hole (BH) in the framework of general relativity. It turns out that four types of configuration of the magnetic connection (MC) are generated, i.e., MC of the BH with the remote astrophysical load (MCHL), MC of the BH with the disc (MCHD), MC of the plunging region with the disc (MCPD) and MC of the inner and outer disc regions (MCDD). It turns out that the Blandford-Znajek (BZ) process can be regarded as one type of MC, i.e., MCHL. In addition, we propose a scenario for fitting the quasi-periodic oscillations in BH binaries based on MCDD associated with the magnetic reconnection.
