Charged Particle Circular Orbits around Weakly Charged and Magnetized Kerr Black Holes

Abstract We study the circular orbits of charged particles around a weakly Kerr black hole immersed in weak, axisymmetric magnetic field. First, we review neutral particles. then and magnetized hole. The case is investigated thereafter. investigate, particular, effect electromagnetic forces on particles’ innermost stable orbits. examine conditions for existence negative-energy possibility emergence gap or double orbit thin accretion disks. Some interesting astrophysical consequences our findings are discussed as well.
