Abstract

We calculate the gravitational self force acting on a pointlike particle orbiting a Schwarzschild black hole. For this purpose, first, we solve the (1+1)-dim field equations for the Lorenz-gauge perturbations by using a time-domain code. Then we derive each multipole mode of the full force from the given perturbation. Finally, we apply the "mode sum" scheme to obtain the physical self force. We evaluate the correction to the orbital frequency due to the conservative self-force effect. We also show that the temporal component of the self force balances with the total energy flux of the gravitational-wave radiated to infinity and through the event horizon.
