Abstract

In this work, we investigate the structural and physical properties of anisotropic compact stars by incorporating the Einasto dark matter density profile within the f ( R, T ) gravity framework. The primary objective is to understand how the interplay between modified gravitational dynamics and dark matter influences the behavior of compact stellar systems. We construct physically viable stellar configurations by solving the modified field equations under appropriate boundary and matching conditions. The resulting models are analyzed using key physical criteria such as regularity, energy conditions, and stability requirements, including the behavior of the anisotropy factor and the adiabatic index. Our analysis, applied to five well-known compact star models, demonstrates that the proposed framework yields consistent and realistic solutions, offering deeper insights into the role of extended gravity theories and dark matter in astrophysical modeling.
