Boson Stars with Nontrivial Topology

Understand

We construct boson star solutions in the presence of a phantom field, allowing for a nontrivial topology of the solutions.

• The wormholes residing at the core of the configurations lead to a number of qualitative changes of the boson star solutions.
• In particular, the typical spiraling dependence of the mass and the particle number on the frequency of the boson stars is lost.
• Instead, the boson stars with nontrivial topology approach a singular configuration in the limit of vanishing frequency.
