Abstract

The orbit of a particle (mass μ) around the Kerr black hole (mass M) is approximately geodesic in the zeroth order of μ/M, and is characterized by three 'constants' of motion, the energy, angular momentum, and Carter constant. In the next order, the orbit deviates from geodesic by the effect of radiation reation. We give the change rates of these 'constants' of motion in the addiabatic approximation analytically.
