Contours of the observed shadow and the invisible surfaces of a rotating black hole

Summary[edit]

Description
English: Shadow (black) & horizons and ergospheres (white) of a rotating black hole. The dimensionless spin parameter a/M=Jc/G/M² is running from 0 to 1. Units: G=M=c=1 (lengths are in GM/c²). The observer is assumed to be far away from the black hole and stationary with respect to the fixed stars.[1][2][3][4][5][6]
