Abstract

We analyze the scalar synchrotron radiation emitted by a source in circular orbits, stable and unstable, direct and retrograde, around a rotating black hole within the framework of quantum field theory in curved spacetimes at tree level. We also analyze the radiation which escapes to infinity, showing that, in accordance with superradiance, it can be amplified for the case of direct orbits.
