This study investigates anisotropic spherical structures in the framework of modified f(R) gravity, where R is the Ricci scalar, extending general relativity to incorporate additional gravitational effects. We employ the Finch–Skea metric to analyze compact stars using different f(R) models. These models allow us to explore the impact of modified gravity on the internal composition and equilibrium of neutron and strange stars. Key physical parameters, including energy density, radial and tangential pressures, anisotropy, and fundamental forces (gravitational, hydrostatic, and anisotropic), are analyzed through graphical representation. The viability of the models is assessed via energy conditions (NEC, WEC, SEC, and DEC) and the equation of state (EoS) parameter. Additionally, we evaluate the role of anisotropy in the stability of compact objects and compare our results with general relativity to highlight the influence of f(R) gravity on stellar structures. This research contributes to the broader understanding of the modifications to general relativity and their implications for compact astrophysical objects.
