A supersymmetric black ring.
A new supersymmetric black hole solution of five-dimensional supergravity is presented. It has an event horizon of topology S1 x S2. This is the first example of a supersymmetric, asymptotically flat black hole of nonspherical topology. The solution is uniquely specified by its electric charge and two independent angular momenta. These conserved charges can be arbitrarily close, but not exactly...
متن کاملWANDs of the Black Ring
Necessary conditions for various algebraic types of the Weyl tensor are determined. These conditions are then used to find Weyl aligned null directions for the black ring solution. It is shown that the black ring solution is algebraically special, of type Ii, while locally on the horizon the type is II. One exceptional subclass – the Myers-Perry solution – is of type D.
متن کاملA Charged Rotating Black Ring
We construct a supergravity solution describing a charged rotating black ring with S2 × S1 horizon in a five dimensional asymptotically flat spacetime. In the neutral limit the solution is the rotating black ring recently found by Emparan and Reall. We determine the exact value of the lower bound on J2/M3, where J is the angular momentum and M the mass; the black ring saturating this bound has ...
متن کاملBlack Saturn with Dipole Ring
We present a new stationary, asymptotically flat solution of 5D EinsteinMaxwell gravity describing a Saturn-like black object: a rotating black hole surrounded by a rotating dipole black ring. The solution is generated by combining the vacuum black Saturn solution and the vacuum black ring solution with appropriately chosen parameters. Some basic properties of the solution are analyzed and the ...
متن کاملR Corrections to Black Ring Entropy
a black ring, and found a mismatch between supergravity and the CFT. However, such a comparison should take into account the subtle distinction between the asymptotic charges of the black ring and the charges entering the CFT description. We show that using the correct charges yields perfect agreement.
