Boson stars with wormholes at their cores — •Christian Hoffmann, Burkhard Kleihaus, and Jutta Kunz — University of Oldenburg, Oldenburg, Germany
We consider a new type of configurations in Einstein gravity coupled to a phantom field. They represent boson stars with wormholes at their cores. These configurations are obtained with an ordinary complex scalar field, whose self-interaction includes a quartic and a sextic term. The phantom field allows for the non-trivial topology of the configurations. We study the dependence of the global charges like the mass and the particle number on the frequency of the scalar field, and on the throat size of the wormholes.
