Rotating black holes in RandallSundrum II braneworlds
Abstract
We find rotating black hole solutions in the RandallSundrum II (RSII) model, by numerically solving a threedimensional PDE problem using pseudospectral collocation methods. We compute the area and equatorial innermost stable orbits of these solutions. For large black holes compared with the AdS length scale, $\ell$, the black hole exhibits fourdimensional behaviour, approaching the Kerr metric on the brane, whilst for small black holes, the solution tends instead towards a fivedimensional MyersPerry black hole with a single nonzero rotation parameter aligned with the brane. This departure from exact fourdimensional gravity may lead to different phenomenological predictions for rotating black holes in the RSII model to those in standard fourdimensional general relativity. This letter provides a stepping stone for studying such modifications.
