Scalar radiation from a source rotating around a regular black hole
arXiv:1906.03778 · doi:10.1103/PhysRevD.100.024012
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-Nordström black hole.
