Image: Ergosphere and event horizon of a rotating black hole (no animation)
Description: 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 coordinate-systems are Boyer-Lindquist- and cartesian Kerr-Schild-coordinates. The axes are in units of GM/c². Animation: click here to start
