Abstract: This work is devoted to transforming the known cosmological solution of Kohler–Chao–Tikekar into an anisotropic interior solution using the framework of Gravitational Decoupling by minimal geometric deformation. The resulting interior solution fulfils the fundamental physical acceptability stellar conditions for a specific set of compactness factors. The stability of the model is also investigated.

In weak field limits, we compute the deflection angle of gravitational decoupling extended black hole Solution black hole solution. We obtained the Gaussian optical curvature by examining the null geodesic equations with the help of Gauss–Bonnet theorem. We also looked into the deflection angle of light by black hole in weak field limits with the use of the Gibbons Werner method. We verify the graphical behaviour of the black hole after determining the deflection angle of light. Additionally, in the presence of the plasma medium, we also determine the deflection angle of the light and examine the graphical behaviour. Further, we compute the Einstein ring via gravitational decoupling extended black hole solution. We also compute the quasi-periodic oscillations and discuss their graphical behaviour.

In the context of this endeavor, we establish a simple protocol for formulating interior stellar solutions that exhibit spherically symmetric configurations against the backdrop of relativistic gravitational decoupling through radial metric deformation (minimal geometric deformation scheme). In this pursuit, we make use of the vanishing complexity factor ($$\widetilde{Y}_{TF}$$ Y ~ TF ) condition, based on Herrera’s (Phys Rev D 97, 044010, 2018) innovative concept regarding the complexity of static or slowly evolving spherical matter configurations. The idea of a complexity factor emerges as the outcome of the orthogonal splitting of the Riemann–Christoffel tensor, which yields different scalar functions, known as structure scalars. The protocol is demonstrated by employing the Buchdahl and Tolman relativistic stellar ansatzes as isotropic seeds. Both of these ansatzes exhibit similar physical features, with a minor variation in their magnitudes in the case of $$\widetilde{Y}_{TF}\ne 0$$ Y ~ TF ≠ 0 , where $$0\le \alpha <1$$ 0 ≤ α < 1 , and $$\alpha $$ α represents a coupling parameter. However, when $$\widetilde{Y}_{TF}=0$$ Y ~ TF = 0 , the Buchdahl stellar ansatz exhibits a uniform density matter configuration, while the Tolman model features an increasing pressure profile. The obtained relativistic stellar models satisfy the basic viability constraints required for the physically realistic configurations.
