Impacts of complexity factor on the transition of fluid configurations from isotropic to anisotropic environment and vice versa

This article presents a study on the process of isotropization and properties of stellar models with different complexity factors, which was introduced by Herrera (Phys Rev D 97:044010, 2018). We consider gravitational decoupling via MGD (Minimal Geometric Deformation) approach for spherically symmetric systems with static background and explore the scenarios where the isotropization of an anisotropic solution of Einstein field equations is possible. Moreover, we work on generating the new analogues of Durgapal-Fuloria model under different conditions associated with complexity factor. The physical existence and stability of the new stellar models have been discussed in details with the help of different potent tools.
