Abstract

We discuss the basic properties of a class of static and spinning black ringoids (Br) in d = 7 spacetime dimensions. These asymptotically flat solutions of the vacuum Einstein equations possess an S² × S³ event horizon topology. They are found for a specific metric ansatz and can be viewed as natural higher dimensional counterparts of the d = 5 black rings (BRs). Similar to that case, the static configurations are supported against collapse by conical singularities. We provide evidence for the existence of balanced solutions which are spinning and possess two equal magnitude angular momenta.
