On Cauchy Surfaces in Conformally Stationary Spacetimes
A criterion for a spacelike hypersurface in a conformally stationary spacetime to be a Cauchy hypersurface is given. The criterion is based on the forward and the backward completeness of a non-reversible Finsler metric associated to the hypersurface.
متن کاملRigidly Rotating Strings in Stationary Axisymmetric Spacetimes
In this paper we study a motion of a rigidly rotating Nambu-Goto test string in a stationary axisymmetric background spacetime. As special examples we consider rigid rotation of strings in a flat spacetime, where explicit analytic solutions can be obtained, and in the Kerr spacetime.
متن کاملExplicit multipole moments of stationary axisymmetric spacetimes
In this article we study multipole moments of axisymmetric stationary asymptotically flat spacetimes. We show how the tensorial recursion of Geroch and Hansen can be reduced to a recursion of scalar functions. We also demonstrate how a careful choice of conformal factor collects all moments into one complex valued function on R, where the moments appear as the derivatives at 0. As an applicatio...
متن کاملEnergy Radiation of Charged Particles in Conformally Flat Spacetimes
Original abstract: Consider the worldline of a charged particle in a static spacetime. Contraction of the time-translation Killing field with the retarded electromagnetic energy-momentum tensor gives a conserved electromagnetic energy vector which can be used to define the radiated electromagnetic energy. This note points out that for a conformally flat spacetime, the radiated energy is the sam...
متن کاملExistence of Standard Splittings for Conformally Stationary Spacetimes
Let (M, g) be a spacetime which admits a complete timelike conformal Killing vector field K. We prove that (M, g) splits globally as a standard conformastationary spacetime with respect to K if and only if (M, g) is distinguishing (and, thus causally continuous). Causal but non-distinguishing spacetimes with complete stationary vector fields are also exhibited. For the proof, the recently solve...
