Gravitational cracking and complexity in the framework of gravitational decoupling

In this work we analyze the stability of self gravitating spheres in the context of gravitational cracking. Besides exploring the role played by the anisotropy in the occurrence of cracking, we also study the effect of the complexity factor recently introduced by L. Herrera in [Phys. Rev. D 97, 044010 (2018)]. The models under study correspond to anisotropic solutions obtained in the framework of the gravitational decoupling. The effect that the variation of the decoupling parameter and the compactness of the source have on the behavior of the radial force is studied in detail.
