Summary[edit]

Description
English: Diagram of the static limit (ergosphere) and the inner and outer event horizons of a rotating black hole.
"a" is the Spin parameter of the rotating black hole; with a low spin-parameter the ergosphere converges to an ellipsoid, while with a high spin-parameter it resembles a pumpkin-shape. The axes are in units of GM/c². If a=0 both coordinate systems reduce to Schwarzschild.
