Charged anisotropic gravitational decoupled strange stars via complexity factor

Abstract

This paper develops a charged anisotropic spherically symmetric strange star model by constructing an exact solution of the field equations through the gravitational decoupling approach. We employ minimal geometric deformation through which the initial decoupled system is divided into Einstein–Maxwell and quasi-Einstein systems. We choose a known solution for isotropic spherical matter distribution with MIT bag equation of state including electromagnetic field and generalize it to an anisotropic model by solving quasi-Einstein field equations using complexity factor. We study the physical viability of the resulting charged anisotropic solution by plotting metric functions, density, pressure, anisotropy parameter, energy conditions, and stability criterion for the strange star candidates SAXJ1808.4-658,SMCX-1,4U1538-52 as well as HERX-1. It is noticed that all the physical aspects are well-behaved, ensuring the physical acceptability of the developed models.
