Evolution of Angular Momentum and Center of Mass at Null Infinity
نویسندگان
چکیده
We study how conserved quantities such as angular momentum and center of mass evolve with respect to the retarded time at null infinity, which is described in terms a Bondi–Sachs coordinate system. These evolution formulae complement classical Bondi loss formula for gravitational radiation. They are further expressed potentials shear news tensors. The consequences that follow from these (1) Supertranslation invariance fluxes CWY quantities. (2) A conservation law à la Christodoulou. (3) duality paradigm infinity. In particular, supertranslation distinguishes definitions.

An angular momentum bound at null infinity
We prove an inequality relating the trace of the extrinsic curvature, the total angular momentum, the centre of mass, and the Trautman-Bondi mass for a class of gravitational initial data sets with constant mean curvature extending to null infinity. As an application we obtain non-existence results for the asymptotic Dirichlet problem for CMC hypersurfaces in stationary space-times.
متن کاملThe evolution of black–hole mass and angular momentum
We show that neither accretion nor angular momentum extraction are likely to lead to significant changes in the mass M1 or angular momentum parameter a∗ of a black hole in a binary system with realistic parameters. Current values of M1 and a∗ therefore probably reflect those at formation. We show further that sufficiently energetic jet ejection powered by the black hole’s rotational energy can ...
متن کاملAngular momentum and mass evolution of contact binaries
Various scenarios of contact binary evolution have been proposed in the past, giving hints of (sometimes contradictory) evolutionary sequence connecting A-type and W-type systems. As the components of close detached binaries approach each other and contact binaries are formed, following evolutionary paths transform them into systems of two categories: A-type and W-type. The systems evolve in a ...
متن کاملThe angular momentum evolution of low-mass stars
We present a model for the evolution of surface rotation of stars in themass range from 0.5 to 1.1M , from their first appearance in theHRdiagramasTTauri stars up to the age of the Sun. The model is based on 3 assumptions: i) nearly solid-body rotation, ii) pre-main sequence disk locking, iii) wind braking. The initial conditions and the calibration of the braking law are completely determined ...
متن کاملOn certain quasi-local spin-angular momentum expressions for large spheres near the null infinity
The recently suggested quasi-local spin-angular momentum expressions, based on the Bramson superpotential and on the holomorphic or anti-holomorphic spinor fields, are calculated for large spheres near the future null infinity of asymptotically flat Einstein–Maxwell spacetimes. It is shown that although the expression based on the anti-holomorphic spinors is finite and unambiguously defined onl...
