Geometry of static $$w=-1/5$$ w = - 1 / 5 perfect fluid spheres in general relativity
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 $$ P=-\rho /5$$ P = - ρ / 5 . These geometries depend on up to four parameters and are static and spherically symmetric. They de...

| Summary: | 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 $$ P=-\rho /5$$ P = - ρ / 5 . These geometries depend on up to four parameters and are static and spherically symmetric. They describe compact spaces with naked central singularities. |
