Entropy of the Stiffest Stars

TL;DR

This paper investigates the properties of the stiffest possible stars under causality constraints, revealing that their entropy scales with the area, which has implications for understanding extreme astrophysical objects.

Contribution

It introduces an analysis of stars with the maximum stiffness allowed by causality and uncovers the area-scaling of their entropy, a novel insight in stellar physics.

Findings

Entropy of stiffest stars scales with area

Stars with maximum stiffness exhibit unique thermodynamic properties

Implications for extreme astrophysical objects and theoretical models

Abstract

We analyze the properties of stars whose interior is described by the stiffest equation of state consistent with causality. We note the remarkable fact that the entropy of such stars scales like the area.
