On Uniqueness of Kerr Space-time near null infinity
نویسندگان
چکیده
We re-express the Kerr metric in standard Bondi-Saches’ coordinate near null infinity I+. Using the uniqueness result of characteristic initial value problem, we prove the Kerr metric is the only asymptotic flat, stationary, axial symmetric, Type-D solution of vacuum Einstein equation. The Taylor series of Kerr space-time is expressed in terms of B-S coordinates and the N-P constants have been calculated. keywords: Kerr solution, Uniqueness Theorem PACS code : 04.20.-q, 04.20.Ex, 04.20.Ha

Light Cone Structure near Null Infinity of the Kerr Metric
Motivated by our attempt to understand the question of angular momentum of a relativistic rotating source carried away by gravitational waves, in the asymptotic regime near future null infinity of the Kerr metric, a family of null hypersurfaces intersecting null infinity in shearfree (good) cuts are constructed by means of asymptotic expansion of the eikonal equation. The geometry of the null h...
متن کاملThe Asymptotic Structure of Algebraically Special Space – times
It is shown that the only vacuum algebraically special space-time that is asymptotically simple is Minkowski space. The structure of null infinity for algebraically special space-times satisfying a subset of the vacuum equations is shown to be particularly simple in terms of the coordinates used in Kerr's original reduction of the field equations. With the assumption of the existence of a globa...
متن کاملSpacelike matching to null infinity
We present two methods to include the asymptotic domain of a background spacetime in null directions for numerical solutions of evolution equations so that both the radiation extraction problem and the outer boundary problem are solved. The first method is based on the geometric conformal approach, the second is a coordinate based approach. We apply these methods to the case of a massless scala...
متن کاملNull Infinity Waveforms from Extreme-Mass-Ratio Inspirals in Kerr Spacetime
We describe the hyperboloidal compactification for Teukolsky equations in Kerr spacetime. We include null infinity on the numerical grid by attaching a hyperboloidal layer to a compact domain surrounding the rotating black hole and the orbit of an inspiralling point particle. This technique allows us to study, for the first time, gravitational waveforms from largeand extreme-mass-ratio inspiral...
متن کاملAsymptotics of Scalar Waves on Long-range Asymptotically Minkowski Spaces
We show the existence of the full compound asymptotics of solutions to the scalar wave equation on long-range non-trapping Lorentzian manifolds modeled on the radial compactification of Minkowski space. In particular, we show that there is a joint asymptotic expansion at null and timelike infinity for forward solutions of the inhomogeneous equation. In two appendices we show how these results a...
