Self Force

In this paper, we study the self-force in the Parikh–Wilczek tunneling model of Hawking radiation for Reissner–Nordström (RN) black holes. We conclude that the repulsive self-force speeds up the emission and the radiation becomes an irreversible process. We also find an upper bound of charge–mass ratio for emitted particles.

We adopt the Dirac–Detweiler–Whiting radiative and regular effective field in curved spacetime. Thereby, we derive straightforwardly the first order perturbative correction to the geodesic of the background in a covariant form, for the extreme mass ratio two-body problem. The correction contains the self-force contribution and a background metric-dependent term.

Self Force

We consider the radial, conservative self force for simple systems undergoing gravitational-radiation damping in the extreme mass ratio limit. We argue that the conservative force acting on a pointlike mass in orbit around a black hole may have a measurable effect on the wave forms, via an induced (retrograde) cumulative precession of the periastron. This effect is strongest for high values of the orbital eccentricity. We also show that the nonradiative modes of the field contribute to the total conservative force.
