Gravitational radiation, gravitational collapse, and numerical relativity.
Abstract
The generation of spacetime by a computer and the application of numerical relativity to relativistic astrophysics are examined. The procedure used to calculate the total energy and the waveform of the emitted radiation is described. The accuracy of the code of Stark and Piran (1985) developed from the scheme of Bardeen and Piran (1983) and Piran (1982) is evaluated. The problem of generating gravitational radiation by a rotating, axisymmetric, stellar collapse is discussed; the results of the emission of gravitational radiation reveal that the efficiency of emission of gravitational radiation increases with angular momentum and that most of radiation is emitted in the + mode.
