Abstract
In this study, we have explored an anisotropic stellar configuration by applying the Karmarkar condition in the framework of [Formula: see text] [where [Formula: see text] and [Formula: see text] stand for torsion and trace of energy–momentum tensor (EMT)] gravity. We have developed field equations of [Formula: see text] gravity for a spherically symmetric line element and considered a viable [Formula: see text] model, i.e. [Formula: see text] (where [Formula: see text] and [Formula: see text] are arbitrary constants) for meaningful results. Following [S. K. Maurya, B. S. Ratanpal and M. Govender, Ann. Phys. 382 (2017) 36], a spherically symmetric solution of embedding class I has been explored which resulted into a generalized compact stellar model. For the evaluation of unknown parameters, we use the matching conditions at the boundary by taking spherical spacetime metric as interior and Schwarzschild spacetime solution as exterior spacetime metric. The viability of our proposed model is checked by exploring the nature of thermodynamical variables ([Formula: see text], [Formula: see text], [Formula: see text]), anisotropy, energy condition, Tolman–Oppenheimer–Volkov (TOV) forces, Abreu condition, equation of state parameters and adiabatic index taking the observational data of different compact stars like PSR J14162230, 4U 160852, Cen X3, EXO 1785248 and SMC X1. Our stellar model is found.
