Gravitationally decoupled anisotropic compact stars immersed in Dehnen-(1,4,0) density profiles
Abstract
The term cosmic dark matter is commonly studied in the context of galactic rotation profiles, particularly along the outer galactic halo. However, its influence may differ significantly in dense-matter astrophysical configurations characterized by strong gravitational fields. In this study, we construct stellar structures developed within the framework of a Dehnen–(1,4,0) halo profile using the well-known Kohler–Chao–Tikekar geometry. The proposed model is driven by an anisotropic fluid coupled with a dark matter component. The aim is to develop the dense-matter, anisotropic astrophysical systems through the framework of geometric decoupling using the minimal geometric deformation scheme. In this context, the temporal component of the auxiliary sector is interpreted as the dark matter sector. A thorough graphic evaluation is conducted to confirm the feasibility of the proposed model, supported by observational data from a set of modeled stellar configurations.
