ResumoThe present paper is designed to study the structure of some compact objects such as P S R J 1614 − 2230 , L M X B 4 U 1608 − 52 , C e n X − 3 , E X O 1785 − 248 and S M C X − 1 in the framework of f ( T , τ ) gravity, where τ and T represent the trace of energy–momentum tensor and torsion scalar, respectively. For this work, we use anisotropic fluid distribution filled in spherical symmetric geometry providing the interior of star model and utilize the off-diagonal tetrad components for deriving the corresponding set of field equations. We construct stellar structure by using a well-known model of f ( T , τ ) gravity, given by f ( T , τ ) = α T ( r ) 2 + β τ ( r ) + ϕ , where α , β and ϕ are arbitrary constants. This model has interesting cosmological properties, in addition to providing an effective dark energy sector explanation (Harko et al., 2014). For checking viability of the constructed model, we set α < 0 , β < 0 and discuss physical and stability features like anisotropy, energy conditions, EoS parameters, TOV equation, redshift, compactness and mass function of strange stars. It is found that these features comprehensively match with the realistic nature of compact stars in the realm of f ( T , τ ) gravity. • This manuscript deals with the structure of some compact objects in f ( T , τ ) gravity • f ( T , τ ) = α T ( r ) 2 + β τ ( r ) + ϕ model is acquired to study the physical features of such objects. • It is found that our results match with the realistic nature of compact stars.
