Anisotropic strange quark stars with a non-linear equation-of-state
Tóm tắt
We obtain an exact analytical solution to Einstein’s field equations assuming a non-linear equation-of-state and a particular mass function. Our solution describes the interior of anisotropic color flavor locked strange quark stars. All energy conditions are fulfilled, and therefore the solution obtained here is a realistic solution within General Relativity. The mass-to-radius profile is obtained, and the compactness of the star is computed.
