Gravitational decoupled anisotropies in compact stars

Understand

Simple generic extensions of isotropic Durgapal--Fuloria stars to the anisotropic domain are presented.

• These anisotropic solutions are obtained by guided minimal deformations over a self gravitating isotropic system.
• When the isotropic and the anisotropic sector interacts in a purely gravitational manner, the conditions to decouple both sectors by means of the minimal geometric deformation approach are satisfied.
• Hence the anisotropic field equations are isolated resulting a more treatable set.
