Spinning Q-balls and Boson Stars in Anti-de Sitter Spacetime — Jutta Kunz, Eugen Radu, and •Bintoro Subagyo — Institut für Physik, Universität Oldenburg, Postfach 2503, D-26111 Oldenburg, Germany

We construct spinning Q-balls and boson stars in d dimensional anti-de Sitter spacetime. These are smooth, horizonless solutions for gravity coupled to a complex scalar field with a harmonic dependence on time and an azimuthal angle. We find that a class of solutions with a self-interaction potential has a limit corresponding to static solitons with axial symmetry only. We also discuss an exact solution describing spherically symmetric Q-balls in a fixed AdS background.
