Abstract

The scalar wave equation is separated in the field of a charged, rotating Kerr-Newman black hole; properties of the effective potential barriers are assessed. Exact stationary solutions for massless scalar fields in the Kerr-Newman geometry are developed, and the no-hair hypothesis is confirmed. In addition, the proof of Detweiler and Ipser (1973) concerning the stability of Kerr black holes with respect to axisymmetric scalar perturbations is found to be applicable to the Kerr-Newman case as well.
