Abstract

We derive new rotating nonasymptotically flat black ring solutions in five-dimensional Einstein-Maxwell-dilaton gravity with the dilaton coupling constant α=8/3, which arises from a six-dimensional Kaluza-Klein theory. As a limiting case we also find new rotating nonasymptotically flat five-dimensional black holes. The solutions are analyzed and the mass, angular momentum, and charge are computed. A Smarr-like relation is found. It is shown that the first law of black hole thermodynamics is satisfied.
