| contents | This paper presents a novel anisotropic quark star model in the backdrop of mimetic gravitational theory. Our study focuses on the strange quark stars using the MIT bag equation of state (EoS) admitting non-singular Buchdahl metric function. The proposed model matches the interior spacetime of the strange quark star with the exterior Schwarzschild spacetime. Our analysis of the energy conditions, radial and tangential EoSs along with the energy momentum tensor gradients and TOV equilibrium condition analysis support the model's physical validity. Further study of adiabatic index, surface redshift function and speed of sound analysis have demonstrated the stability of the strange quark star in mimetic gravity. Thus, we can say that the model stability and consistency have been validated for various parameter values of the Buchdahl function throughout our study in the context of mimetic gravity. |
