We present a class of exact solutions of Einstein's gravitational–field equations describing spherically symmetric and static anisotropic stellar–type configurations. The solutions are obtained by assuming a particular form of the anisotropy factor. The energy density and both radial and tangential pressures are finite and positive inside the anisotropic star. Numerical results show that the basic physical parameters (mass and radius) of the model can describe realistic astrophysical objects such as neutron stars.

- Anisotropic solutions by gravitational decoupling (2017, background): “8) could indeed be treated as an anisotropic fluid [45,46], which would require one to consider five unknown functions, namely, the two metric functions ν(r) and λ(r), and the effective functions in Eqs.”
- A class of relativistic stars with a linear equation of state (2007, methodology): “Unlike other models (Mak & Harko 2003; Dev & Gleiser 2004), the form of the anisotropic parameter is not chosen a priori in this model.”
- Gravitational decoupled anisotropies in compact stars (2018, background): “Some of them must be chosen by consistency of regularity, stability and (or) energy conditions of relativistic models; see for instance [5, 7, 32].”
