Black holes and gravitational waves. II. Trajectories plunging into a nonrotating hole.
Abstract
The nature of the gravitational radiation emitted by a test particle as it falls into a nonrotating black hole is examined in the case where the test particle is endowed with some orbital angular momentum. Waveforms, spectra, and the total energy of the gravitational waves emitted by test particles of various angular momenta are computed. It is shown that the total energy output may be enhanced by as much as a factor of 50 in comparison with the case of a test particle with no angular momentum and that the higher multipoles contribute a larger percentage of the energy as the angular momentum of the test particle increases. The amount of gravitational energy emitted in the nonaxisymmetric collision of two black holes is briefly considered.
