Discussion of geodesics in Kerr-de Sitter space-time — •Eva Hackmann and Claus Lämmerzahl — ZARM, Universität Bremen

Recently, the geodesic equation in Kerr-de Sitter space-time has been solved analytically (arXiv:0911.1634v1). Using this solution, we discuss chosen geodesics in this space-time. This includes orbits which highlight the influence of the cosmological constant as well as the last stable spherical orbit and the innermost stable circular orbit. In addition, the analytical expressions for the perihelion shift and the Lense-Thirring effect will be discussed and corresponding orbits will be shown.
