Holographic Neutron Stars

TL;DR

This paper constructs holographic duals of neutron stars in AdS space, analyzing their stability and collapse using gravitational equations, and identifies a limit beyond which collapse occurs.

Contribution

It introduces a method to model degenerate stars holographically and determines the critical mass for gravitational collapse in AdS/CFT context.

Findings

Identification of a Chandrasekhar-like limit in holographic stars

Calculation of back-reaction effects using TOV equations

Prediction of black hole formation beyond the critical mass

Abstract

We construct in the context of the AdS/CFT correspondence degenerate composite operators in the conformal field theory that are holographically dual to degenerate stars in anti de Sitter space. We calculate the effect of the gravitational back-reaction using the Tolman-Oppenheimer-Volkoff equations, and determine the "Chandrasekhar limit" beyond which the star undergoes gravitational collapse towards a black hole.
