Dipole perturbations of the Reissner-Nordstrom solution. II. The axial case - art. no. 084003

We study the linear metric perturbations of the Reissner-Nordstrom solution far the case of axial perturbation modes. We find that the well-known pert urbative analysis fails for the case of dipole (l = 1) perturbations, altho ugh valid for higher multipoles. We define new radial functions, with which the perturbation formalism is generalized to all multipole orders, includi ng the dipole. We then complete the solution by constructing the perturbed metric and Maxwell tensors. [S0556-2821(99)00108-3].
