Static Orbits in Rotating Spacetimes — •Lucas Gardai Collodel, Burkhard Kleihaus, and Jutta Kunz — Institut für Physik, Universität Oldenburg, Postfach 2503 D-26111 Oldenburg, Germany

We show that under certain conditions an axisymmetric rotating spacetime contains a ring of points in the equatorial plane, where a particle at rest with respect to an asymptotic static observer remains at rest in a static orbit. We illustrate the emergence of such orbits for boson stars. Further examples are wormholes, hairy black holes and Kerr-Newman solutions.
