Abstract

We show that the general framework proposed in arXiv:1410.0581 for the study of asymptotically flat vacuum black objects with k+1k+1 equal magnitude angular momenta in D5D\geq 5 spacetime dimensions (with 0k[D52]0\leq k\leq \big[\frac{D-5}{2} \big]) can be extended to the case of Einstein-Maxwell-dilaton (EMd) theory. This framework can describe black holes with spherical horizon topology, the simplest solutions corresponding to a class of electrically charged (dilatonic) Myers-Perry black holes. Balanced charged black objects with Sn+1×S2k+1 S^{n+1} \times S^{2k+1} horizon topology can also be studied (with D=2k+n+4D=2k+n+4). Black rings correspond to the case k=0k=0, while the solutions with k>0k>0 are black ringoids. The basic properties of EMd solutions are discussed for the special case of a Kaluza-Klein value of the dilaton coupling constant. We argue that all features of these solutions can be derived from those of the vacuum seed configurations.
