Geometry of static $w=-1/5$ perfect fluid spheres in general relativity

General Relativity and Quantum Cosmology 2022-05-11 v2

Abstract

We discuss the physical features of two recent classes of analytical solutions of the Einstein equations sourced by an exotic perfect fluid with equation of state P=ρ/5 P=-\rho/5. These geometries depend on up to four parameters and are static and spherically symmetric. They describe compact spaces with naked central singularities.
