New Series of Exact Solutions for Gravitational Fields of Spinning Masses
Abstract
New series of solutions for spacetimes which are regarded as representing the gravitational fields of spinning bound masses is derived from a series of Weyl metrics, following Ernst's formulation on axisymmetric stationary fields. This series of solutions includes the Kerr metric as a member of the simplest one. Except in the case of the Kerr metric, the spacetimes have ring singularities outside event horizons, that is, there exist naked singularities. Therefore, these solutions seem to give a very different picture concerning the ultimate fate of gravitational collapse compared with a current picture such as the IsraelCarter conjecture. The naked ring singularity may become an active energy source of gravitational wave, and yield many interesting phenomena in astrophysics.
