Time evolution of a thin black ring via Hawking radiation

Understand

Black objects lose their mass and angular momenta through evaporation by Hawking radiation, and the investigation of their time evolution has a long history.

• In this paper, we study this problem for a five-dimensional doubly spinning black ring.
• The black ring is assumed to emit only massless scalar particles.
• We consider a thin black ring with a small thickness parameter, $\lambda\ll 1$, which can be approximated by a boosted Kerr string locally.
