Black ringoids: new higher dimensional black objects with non-spherical horizon topology |
|
Abstract |
We discuss the properties of a new class of solutions of Einstein equations reported recently in the literature -- the black ringoids. These asymptotically flat black objects have an $S^{n+1} \times S^{2k+1}$ horizon topology, being supported against collapse by rotation, with $k+1$ equal magnitude angular momenta and no singularity on and outside the horizon. Based on the nonperturbative numerical results found for several values of $(n, k)$, we also propose a general picture for the properties and the phase diagram of these solutions and the associated black holes with spherical horizon topology. |
