“…A comparison of the results (with the set of MP-like solutions included), suggests that, similar to the vacuum case, the k ≥ 1 black ringoids with S 2 × S 2k+1 horizon topology are the natural counterparts of the D = 5 BRs. As noticed in [21], the branch of "fat" D = 5 charged BRs ends in a limiting singular solution with a H = 0 and nonzero j. The same configuration is also approached by the charged MP BHs with maximal j.…”

“…(A similar approach has been used in [18,19] to study the MP BHs in EMd theory with a dilaton coupling constant given by Equation (24) and D = 5 BRs and black Saturns have been constructed in [20,21], in the same model.) The procedure is well known in the literature and works as follows: we first embed the D-dimensional vacuum solutions into a (D + 1) spacetime with a trivial extra coordinate U, ds…”

Abstract:We show that the general framework proposed by Kleihaus et al. (2015) for the study of asymptotically flat vacuum black objects with k + 1 equal magnitude angular momenta in D ≥ 5 spacetime dimensions (with 0 ≤ k ≤ D−5 2 ) 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 S n+1 × S 2k+1 horizon topology can also be studied (with D = 2k + n + 4). Black rings correspond to the case k = 0, while the solutions with k > 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.

In this paper, we investigate a spinning black ring and a charged black ring in the context of gravity's rainbow. By incorporating rainbow functions proposed by AmelinoCamelia, et al. in [1,2] in the metric of the black rings, a considerable modification happens to their thermodynamical properties. We calculate corrections to the temperature, entropy and heat capacity of the black rings. These calculations demonstrate that the behavior of Hawking radiation changes considerably near the Planck scale in gravity's rainbow, where it is shown that black rings do not evaporate completely and a remnant is left as the black rings evaporate down to Planck scale.

“…Some charged rotating dilaton black objects were obtained in five dimensions in this way. They include the charged counterpart of the Myers-Perry black hole [37], the black ring [38], and the black Saturn [39]. More general black ring solutions with double rotation and carrying also a dipole charge were obtained by a related scheme [40]- [43].…”

We construct a class of stationary and axisymmetric solutions to the 5D Einstein-Maxwell-dilaton gravity, which describe configurations of charged rotating black objects with Kaluza-Klein asymptotics. The solutions are constructed by uplifting a vacuum seed solution to six dimensions, performing a boost, and a subsequent circle reduction. We investigate the physical properties of the charged solutions, and obtain their general relations to the properties of the vacuum seed. We also derive the gyromagnetic ratio and the Smarr-like relations. As particular cases we study three solutions, which describe a charged rotating black string, a charged rotating black ring on Kaluza-Klein bubbles, and a superposition of two black holes and a Kaluza-Klein bubble.
