Positivity of the Bondi Mass in Bondi’s Radiating Spacetimes

چکیده
Gravitational waves are predicted by Einstein’s general relativity. They are time dependent solutions of the Einstein field equations which radiate or transport energy. Although they have not been detected yet, the existence of gravitational waves has been proved indirectly from observations of the pulsar PSR 1913+16. This rapidly rotating binary system should emit gravitational radiation, hence lose energy and rotate faster. The observed relative change in period agrees remarkably with the theoretical value .

On the Relation between Adm and Bondi Energy-momenta Ii – Radiative Spatial Infinity
It is a fundamental problem in gravitational radiation what the relation is between the ADM energy-momentum and the Bondi energy-momentum. Ashtekar and Magnon-Ashtekar demonstrated the mass at spatial infinity is the past limit of the Bondi mass taken as the cut approaches the “point” of spatial infinity in the frame of Penrose conformal compactification [2]. It was proved the standard ADM mass...

متن کاملOn the Relation between Adm and Bondi Energy-momenta Iii – Perturbed Radiative Spatial Infinity
Abstract. In a vacuum spacetime equipped with the Bondi’s radiating metric which is asymptotically flat at spatial infinity including gravitational radiation (Condition D), we establish the relation between the ADM total energy-momentum and the Bondi energy-momentum for perturbed radiative spatial infinity. The perturbation is given by defining the “real” time the sum of the retarded time, the ...
متن کاملAn analytic study of Bondi–Hoyle–Lyttleton accretion I. Stationary flows
We prove that the sonic surface of axisymmetric meridional stationary flows is always attached to the accretor, however small, if the adiabatic index of the gas is = 5=3. Using local expansions near a point-like accretor, we extend Bondi’s classification of spherically symmetric flows to axisymmetric flows, introducing the possibility of angular sectors reached by no flow lines, and singular di...
متن کاملOn the Relation between Adm and Bondi Energy-momenta
Abstract. When a spacetime takes Bondi radiating metric, and is vacuum and asymptotically flat at spatial infinity which ensures the positive mass theorem, we prove that the standard ADM energy-momentum is the past limit of the Bondi energy-momentum. We also derive a formula relating the ADM energy-momentum of any asymptotically flat spacelike hypersurface to the Bondi energy-momentum of any nu...
