Scalar radiation from a source rotating around a regular black hole (1906.03778v1)
Published 10 Jun 2019 in gr-qc and hep-th
Abstract: The scalar radiation emitted by a source in geodesic circular orbit around a regular Bardeen black hole is analyzed. We use the quantum field theory in curved spacetime framework to obtain the emitted power of radiation by computing the one-particle emission amplitude of scalar particles in the curved background. We compare our results to a similar setting in the spacetime of a Reissner-Nordstr\"{o}m black hole.
