Gravitational waves emitted by a particle rotating around a Schwarzschild black hole: A semiclassical approach (1703.10648v1)
Published 30 Mar 2017 in gr-qc
Abstract: We analyze the gravitational radiation emitted from a particle in circular motion around a Schwarzschild black hole using the framework of quantum field theory in curved spacetime at tree level. The gravitational perturbations are written in a gauge-invariant formalism for spherically symmetric spacetimes. We discuss the results, comparing them to the radiation emitted by a particle when it is assumed to be orbiting a massive object due to a Newtonian force in flat spacetime.
