On gravitational radiation and the energy flux of matter

Abstract: A suitable derivative of Einstein's equations in the framework of the teleparallel equivalent of general relativity (TEGR) yields a continuity equation for the gravitational energy-momentum. In particular, the time derivative of the total gravitational energy is given by the sum of the total fluxes of gravitational and matter fields energy. We carry out a detailed analysis of the continuity equation in the context of Bondi and Vaidya's metrics. In the former space-time the flux of the gravitational energy is g… Show more

“…Neste trabalho abordamos uma expressão para o momento angular gravitacional na formulação teleparalela, haja vista que a definição de momento energia jáé bem estabelecido [11,25,26]. As definições para o momento angular e energia-momento gravitacionais são invariantes por transformações de coordenadas no espaço tridimensional, pois são projetadas no espaço tangente.…”
