Energy Extraction via Magnetic Reconnection in the Ergosphere of a Rotating Non-Kerr Black Hole

Abstract
Abstract Magnetic reconnection in the ergosphere is investigated for a relativistic plasma around a rotating non-Kerr black hole. For a rotating non-Kerr black hole immersed in a magnetic field generated by an externally material, antiparallel magnetic field line could form in the ergosphere due to frame dragging. Therefore, magnetic reconnection could occur in the ergosphere. This magnetic reconnection may generate negative energy at infinity by redistributing the angular momentum during the process. The results show that, taking into account the effect of the deformed parameter, extraction of energy from a rotating non-Kerr black hole by magnetic reconnection could be enhanced in the presence of a positive deformed parameter.
