That's effectively the Schwarzschild solution unless the a star is rotating very fast. You don't even have to make the assumption that the mass is concentrated at the center, you just assume spherical symmetry. Brent TY, but what's the first thing one must DO, who never heard of Schwartzchild, to derive a geodesic path?

How would we calculate the spacetime curvature in a region around this star?
