Abstract
We study charged and rotating boson stars in five-dimensional Einstein-Maxwell-Chern-Simons theory assuming the two angular momenta associated with the two orthogonal planes of rotation to be equal. Next to the angular momenta, the boson stars carry an electric charge and a magnetic moment. Interestingly, we find new branches of Einstein-Maxwell-Chern-Simons solutions for which the spatial part of the gauge potential possesses nodes. Consequently, the magnetic moment and the gyromagnetic ratio have opposite signs as compared to the solutions on the main branch. For sufficiently large energy density we find that the solutions possess ergoregions.
