Constraining maximum mass limit and physical properties of Durgapal-Fuloria complexity-free solution under gravitational decoupling approach

We present here spherically symmetric anisotropic compact stars under the gravitational decoupling approach. Basically, this approach provides an anisotropic generalization of the Durgapal-Fuloria solution where we have assumed a null complexity factor condition [Herrera, Phys Rev D 97 (2018) 044010] to derive the deformation function [Contreras & Stuchlik, Eur. Phys. J. C 82 (2022) 706]. To determine the matter-energy density and the fluid pressure from the Einstein Field Equations (EFE), we use the generalized Durgapal-Fuloria solution and calculate the physical parameters. We specifically have imposed constraints on the geometric deformation parameter & beta; which affects the physical parametric value significantly. The model, as depicted in Table I as well as in M-R curves, shows consistency with all the physical conditions and presents a viable investigation to the nature of the generalized superdense anisotropic stellar system of the Durgapal-Fuloria type as far as the observational data is concerned.& COPY; 2023 Elsevier B.V.
