Formation and Evaporation of a Naked Singularity in 2D Gravity

TL;DR

This paper investigates the formation and evaporation of a naked singularity in two-dimensional dilaton gravity, proposing a weak censorship mechanism that leads to radiation emission upon singularity formation.

Contribution

It introduces a classical model of naked singularity formation and analyzes its Hawking evaporation within 2D gravity, highlighting a potential weak censorship effect.

Findings

Naked singularity can form from conformal matter in 2D gravity.

Hawking evaporation causes the singularity to explode into radiation.

Large mass singularities are credible within one-loop analysis.

Abstract

We describe a classical configuration of conformal matter forming a naked singularity and discuss its subsequent Hawking evaporation within the context of two dimensional dilaton gravity. The one loop analysis is credible for a large mass naked singularity and suggests the existence of a weak cosmological censorship that would cause it to explode into radiation upon forming.
