Gravitational radiation, energy and reaction on quasispherical black holes
Abstract
Gravitational radiation is locally defined where the wavefronts are roughly spherical. A local energy tensor is defined for the gravitational radiation. Including this energy tensor as a source in the truncated Einstein equations describes gravitational radiation reaction, such as backreaction on a roughly spherical black hole. The energymomentum in a canonical frame is covariantly conserved. The strain to be measured by a distant detector is simply defined.
