论文摘要
我们研究了浸入弱的轴对称磁场中的弱带电的施瓦茨柴尔德黑洞周围带电颗粒的圆形轨道。首先，仅查看仅弱带电且仅磁性弱化的黑洞的中性颗粒和带电的颗粒的圆形轨道。那时，研究了一个弱磁化和充电的黑洞的情况。特别是，我们研究电磁力对带电颗粒最内向的稳定圆形轨道的影响。我们表明，负能量稳定的圆形轨道是可能的，并且可以存在两个带电颗粒的圆形圆形轨道，这些圆形轨道被没有稳定的圆形轨道的间隙隔开。也讨论了我们发现的天体物理方面。
We study the circular orbits of charged particles around a weakly charged Schwarzschild black hole immersed in a weak, axisymmetric magnetic field. We start by reviewing the circular orbits of neutral particles and charged particles around only weakly charged and only weakly magnetized black holes. The case of a weakly magnetized and charged black hole is investigated then. In particular, we study the effect of the electromagnetic forces on the charged particles innermost stable circular orbits. We show that negative energy stable circular orbits are possible and that two bands of charged particles circular orbits, separated by a gap of no stable circular orbits can exist. The astrophysical aspects of our findings are discussed too.
