摘 要：This study addresses the formation of anisotropic compact star models in the background of f(T,■)gravity(where T and ■ represent the torsion and trace of the energy momentum tensor,respectively).f(T,■) gravity is an extension of the f(T) theory,and it allows a general non-minimal coupling between T and ■.In this setup,we apply Krori and Barua’s solution to the static spacetime with the components ξ=Br~2+c and Ψ=Ar~*** develop viable solutions,we select a well-known model f(T,■)=aT~m+β■+φ(where α and β are coupling parameters,and φ indicates the cosmological constant).We adopt the conventional matching of interior and exterior space time to evaluate the unknowns,which are employed in the stellar *** present a comprehensive discussion on the stellar properties to elaborate the anisotropic nature of compact stars corresponding to well-known models:PSRJ1416-2230,4U1608-52,CenX-3,EX01785-248,and *** physical analysis,it is observed that the solution of compact spheres satisfy the acceptability criteria,and its models behave optimally and depict stability and consistency,in accordance with f(T,■) gravity.
