Orbits around a charged doubly spinning black ring — •Saskia Grunau, Valeria Kagramanova, and Jutta Kunz — Carl von Ossietzky Universität Oldenburg

We analyze the geodesics of test particles and light in the five dimensional charged doubly spinning black ring spacetime. Apparently it is not possible to separate the Hamilton-Jacobi-equation for charged doubly spinning black rings in general, so we concentrate on special cases: null geodesics in the ergosphere and geodesics on the two rotational axes of the charged doubly spinning black ring. We present analytical solutions to the geodesic equations for these special cases. Using effective potential techniques we study the motion of test particles and light and discuss the corresponding orbits
