| description | Eur. Phys. J. C 85, 26(2025) Recently, magnetic reconnection has attracted considerable attention as a
novel energy extraction mechanism, relying on the rapid reconnection of
magnetic field lines within the ergosphere. We have investigated the properties
of the energy extraction via magnetic reconnection in a Konoplya-Zhidenko
rotating non-Kerr black hole spacetime with an extra deformation parameter. Our
results show that the positive deformation parameter expands the possible
region of energy extraction and improves the maximum power, maximum efficiency,
and the maximum ratio of energy extraction between magnetic reconnection and
the Blandford-Znajek process. This means that in the Konoplya-Zhidenko rotating
non-Kerr black hole spacetime one can extract more energy via magnetic
reconnection than in the Kerr black hole case. These effects of the deformation
parameter may provide valuable clues for future astronomical observations of
black holes and verification of gravity theories. |
