The interior space-time metric for a rotating spherical star

  1. Feb 8, 2009 #1
    I was looking for a space time metric that describes the INTERIOR of spherically symmetric rotating stars. However, wherever I look it is always the metric for an exterior of "slowly rotating star" (frame dragging effect) or something similar to it but always the metric AROUND the object (exterior). Is there any solution for interior of the star? I know already the interior Schwarzchild solution but is there the same for a rotating star? Thanks in advance.

    Finding the interior solution for something approximating a Kerr Metric is an open problem, as I recall.

    Good luck, and keep us informed?
