Phys. Rev. D 73, 084023 (2006) [6 pages]Kerr metric in Bondi-Sachs formReceived 15 December 2005; revised 24 February 2006; published 21 April 2006 A metric representing the Kerr geometry has been obtained by Pretorius and Israel. We make coordinate transformations on this metric, to bring it into Bondi-Sachs form. We investigate the behavior of the metric near the axis of symmetry and confirm elementary flatness, and we also confirm that it is asymptotic to the Bondi-Sachs form of the Schwarzschild geometry. The results obtained here are needed so that numerical relativity codes based on the characteristic formalism can be applied to a situation that contains a rotating black hole. © 2006 The American Physical Society URL:
