Particle ionization near weakly charged black hole
Original language description
In many astrophysical scenarios, the charge of the black hole is often neglected due to unrealistically large values of the charge required for the Reissner-Nordstrom spacetime metric. However, black holes may possess a small electric charge dueto various selective accretion mechanisms. In this paper we investigate the processof ionization of a neutral particle in the vicinity of a weakly charged non-rotating black hole and calculate the energy of an ionized particle in a chosen scenario. High energy obtained by a charged particle after the ionization process can serve as a distinguishing signature of the weakly charged black hole.
