Non-singular anisotropic solutions for strange star model in $$f(\mathcal {R},\mathcal {T},\mathcal {R}_{\zeta \gamma }\mathcal {T}^{\zeta \gamma })$$ gravity theory

Abstract This article focuses on different anisotropic models within the framework of a specific modified $$f(\mathcal {R},\mathcal {T}, \mathcal {R}_{\zeta \gamma }\mathcal {T}^{\zeta \gamma })$$ f ( R , T , R ζ γ T ζ γ ) gravity theory. The study adopts a static spherically symmetric spacetime to determine the field equations for two different modified models: (i) $$f(\mathcal {R},\mathcal {T},\mathcal {R}_{\zeta \gamma }\mathcal {T}^{\zeta \gamma })=\mathcal {R}+\eta \mathcal {R}_{\zeta \gamma }\mathcal {T}^{\zeta \gamma }$$ f ( R , T , R ζ γ T ζ γ ) = R + η R ζ γ T ζ γ , and (ii) $$f(\mathcal {R},\mathcal {T},\mathcal {R}_{\zeta \gamma }\mathcal {T}^{\zeta \gamma…
