Exact density-potential pairs from the holomorphic Coulomb field
Abstract
We show how the complex-shift method introduced by Appell in gravity to the case of a point mass (and applied among others in electrodynamics by Newman, Carter, Lynden-Bell, and Kaiser to determine remarkable properties of the electromagnetic field of rotating charged configurations), can be extended to obtain new and explicit density-potential pairs for self-gravitating systems departing significantly from spherical symmetry. The rotational properties of two axysimmetric baroclinic gaseous configurations derived with the proposed method are illustrated.
