Null geodesics in accelerating black hole spacetimes — •Eva Hackmann — ZARM, Universität Bremen

The accelerating black hole spacetime, also known as C-metric, is a two parameter solution of the vacuum field equations with conical singularities on the z-axes. We discuss null geodesics in the C-metric using spherical-type coordinates as introduced by Griffith and Podolsky (Class. Quantum Grav. 23:6745, 2006), which reduce to the familiar form of the Schwarzschild metric in Boyer-Lindquist coordinates for vanishing acceleration. The characteristic features of null geodesics in this spacetime are studied and an analytical solution of the equation of motion will be presented. We also discuss possible locations of timelike stable circular orbits and the observation of light emitted from there.
