摘要: We derive two new retarded solutions in the teleparallel theory equivalent to general relativity (TEGR). One of these solutions gives a divergent energy. Therefore, we use the regularized expression of the gravitational energy--momentum tensor, which is a coordinate dependent. A detailed analysis of the loss of the mass of Bondi space--time is carried out using the flux of the gravitational energy--momentum.

Abstract: We derive two new retarded solutions in the teleparallel theory equivalent to general relativity (TEGR). One of these solutions gives a divergent energy. Therefore, we use the regularized expression of the gravitational energy–momentum tensor, which is a coordinate dependent. A detailed analysis of the loss of the mass of Bondi space–time is carried out using the flux of the gravitational energy–momentum.

Key words: teleparallel equivalent of general relativity, energy–momentum tensor, Bondi mass, gravitational radiation
