Five-dimensional wormholes at the core of rotating boson stars — •Sarah Kahlen, Burkhard Kleihaus, and Jutta Kunz — Carl von Ossietzky Universität, Oldenburg

We consider rotating wormhole spacetimes in five dimensions whose throat is immersed in bosonic matter. They represent boson star like configurations with non-trival topology supported by a phantom field. We discuss their physical properties and point out an unexpected richness of configurations. We also present their geometrical features like the existence of single throat and double throat wormholes. We show, that rotation can stabilize these systems.
