Webwhere the Boyer-Lindquist coordinates are: and where the rotation parameter a is defined by One has ; an object with higher angular momentum than corresponding to a = M cannot stick together. The horizon is the surface which one when using the coordinates of a distant observer in flat space will never see anything pass. It is not a real ... WebDec 19, 2024 · The Kerr metric has spheroidal symmetry, due to the presence of a non zero rotation. So Boyer-Lindquist coordinates are specially adapted for this symmetry.
