New entropy formula for Kerr black holes
Hernan Gonzalez, Daniel Grumiller, Wout Merbis, Raphaela Wutte
TL;DR
This paper proposes a novel entropy formula for Kerr black holes, extending it to Kerr-Taub-NUT black holes, inspired by recent developments in 3D black holes and cosmologies with soft hair.
Contribution
The paper introduces a new entropy formula applicable to Kerr and Kerr-Taub-NUT black holes, inspired by recent advances in soft hair and 3D black hole research.
Findings
Kerr black holes obey the new entropy formula
Kerr-Taub-NUT black holes also follow the formula
The formula is inspired by soft hair and 3D black hole results
Abstract
We introduce a new entropy formula for Kerr black holes inspired by recent results for 3-dimensional black holes and cosmologies with soft Heisenberg hair. We show that also Kerr-Taub-NUT black holes obey the same formula.
