black hole model
(BH model, model black hole, model BH)
(description of a BH using math or computation)
By black hole model (or model black hole), I refer to mathematical
structures or computer calculations demonstrating aspects of black holes.
Black holes vary only in mass, electric charge, and rotation,
though interactions with other objects (black hole mergers, accretion disks)
can lead to modeling challenges.
Some mathematical models:
- Schwarzschild Black Hole - a mathematical model of a black hole that is not rotating and has no charge.
- Kerr Black Hole - mathematical model including rotation.
- Reissner-Nordström black hole - mathematical model including charge.
- Kerr-Newman Black Hole - mathematical model including both rotation and charge.
These are exact according to general relativity, but less-than-complete models are
sometimes selected as simplified approximations of cases where charge and/or
rotation is small enough to exert little influence.
