Chris M. Chambers, William A. Hiscock, Brett Taylor (Montana State, University)
TL;DR
This paper investigates how Kerr black holes lose mass and angular momentum through scalar radiation emission, revealing a final state with a specific nonzero spin parameter.
Contribution
It introduces a detailed analysis of black hole evolution under scalar Hawking radiation, identifying a characteristic final spin state.
Findings
Black holes lose mass and angular momentum via scalar radiation.
The final spin parameter stabilizes at approximately 0.555.
The evolution process leads to a nonzero angular momentum state.
Abstract
We study the evolution of a Kerr black hole emitting scalar radiation via the Hawking process. We show that the rate at which mass and angular momentum are lost by the black hole leads to a final evolutionary state with nonzero angular momentum, namely .
