This space's Killing fields consist of two vectors and, extraordinarily, a tensor.
One of the four conserved quantities in this system is known as Carter's constant, after its discoverer. This space's Killing fields consist of two vectors and, extraordinarily, a tensor. The relativistic n-pole moment of this system is given by its mass times the quantity i times the specific angular momentum to the n. This is the simplest spacetime containing a region where all time-like paths are co-rotating. The Boyer-Lindquist coordinates for this model give delta equals 0 and rho equals 0 for its two singularities, one of which is a curvature singularity, which produce a critical surface in the shape of an oblate spheroid. This system allows for the possibility of energy extraction from its ergosphere via the Penrose process. A degenerate case of this model in which the angular momentum is 0 is the Schwarzschild model. For 10 points, name this model that describes the geometry of spacetime around a rotating black hole which, when it is charged, is co-named for Newman.
