Geodesic Motion in Black Ring Space-Times — •Saskia Grunau1, Valeria Kagramanova1, Jutta Kunz1, and Claus Lämmerzahl1, 2 — 1Carl von Ossietzky Universität Oldenburg — 2ZARM, University Bremen
We present analytical solutions of the geodesic equations of test particles and light in five dimensional black ring space-times for special cases, since it does not appear possible to separate the Hamilton-Jacobi-equation for black rings in general. Based on the study of the polynomials in the equations of motion we characterize the motion of test particles and light and discuss the associated orbits. We compare the motion around singly spinning black rings, doubly spinning black rings and charged supersymmetric black rings.
