I've been trying to find out the relationship between Kerr-Newman BH mass, Angular momentum and Charge. But I cannot find it. If some know please let me know.
Thank you
Thank you
Orodruin said:Why do you think there is such a relationship? These are independent properties.
That is just exchanging the angular momentum for a length scale parameter. Since that parameter is a priori independent of the mass, the angular momentum does not have a one to one relationship with the mass. As an example, the Schwarzschild black hole is a Kerr black hole with J = 0 (or, equivalently, a=0).Hiranya Pasan said:(J=aM)

A Kerr-Newman black hole is a type of black hole that has both mass and angular momentum (spin) as well as an electric charge. It was first described by Roy Kerr and Ezra Newman in 1963 and is a solution to the Einstein-Maxwell equations in general relativity.
The mass of a Kerr-Newman black hole is directly related to its angular momentum and charge through the Kerr-Newman metric. The more angular momentum and charge a black hole has, the higher its mass will be.
Yes, a Kerr-Newman black hole can have zero angular momentum. In this case, it would be a Schwarzschild black hole with only mass and no spin or charge.
The charge of a Kerr-Newman black hole affects its properties in several ways. It can change the shape of the event horizon and the ergosphere, and also affects the strength of the gravitational and electric fields near the black hole.
There are currently no known real-life examples of Kerr-Newman black holes. However, some black holes in space have been observed to have both spin and charge, making them potential candidates for being Kerr-Newman black holes.
