Zusammenfassung: | The present manuscript throws light on the existence of an electrically charged compact stellar model and explores the behavior of complexity factor, proposed by Herrera (2018), against the selected model in the background of f(R,T) gravity (R is the Ricci scalar, while T is the trace of energy–momentum tensor). The set of f(R,T) field equations has been solved by choosing Adler Finch–Skea solution, where the presence of electromagnetic radiations have also been considered in the stellar interior. For the space–time continuity, the boundary conditions have been described by taking Reissner–Nordström solution as exterior space–time. The physical analysis has been made by choosing the radii of PSR J 1614-2230 and SAX J 1808.4-3658, which shows that the model is physically consistent in the realm of f(R,T) gravity, and we obtain more compact stellar configurations for negative values of coupling constant λ. The implications of λ on the total mass and complexity factor of the stellar model have been explored in details. The total mass has been found maximum for λ=−0.4 and minimum for λ=0.4. The complexity factor is increased for negative values of λ as compared to the other scenarios (i.e., λ≥0). The comparison of anisotropy factor and complexity factor has been made, which indicates the presence of less anisotropy in pressure distribution and more inhomogeneity in energy density of the fluid configuration for negative values of λ.
