论文摘要
我们研究了浸入弱的轴对称磁场的弱带电的Kerr黑洞周围带电颗粒的圆形轨道。首先，我们回顾中性颗粒的圆形轨道。然后，我们回顾一个弱带电荷的Kerr黑洞和弱磁化的Kerr黑洞周围带电颗粒的圆形轨道。此后研究了一个弱磁化和带电的黑洞的情况。我们特别研究电磁力对带电颗粒最内向的圆形轨道的影响。我们检查了存在负能量稳定圆形轨道的条件，以及在薄积分磁盘中出现间隙或双轨道的可能性。我们的发现中也讨论了一些有趣的天体物理后果。
We study the circular orbits of charged particles around a weakly charged Kerr black hole immersed in a weak, axisymmetric magnetic field. Firstly, we review the circular orbits of neutral particles. We then review the circular orbits of charged particles around a weakly charged Kerr black hole and weakly magnetized Kerr black hole. The case of a weakly magnetized and charged black hole is investigated thereafter. We investigate, in particular, the effect of the electromagnetic forces on the charged particles' innermost stable circular orbits. We examine the conditions for the existence of negative-energy stable circular orbits and the possibility of the emergence of a gap or double orbit in thin accretion disks. Some of the interesting astrophysical consequences of our findings are discussed as well.
