Physically viable strange quark star models in modified teleparallel gravity.

The aim of this paper is to develop the isotropic and anisotropic quark stars configurations in the context of f (T ,) gravity in the static spherically symmetric background. To explore the combined effects of torsion scalar T and the trace of energy–momentum tensor (EMT) on relativistic astrophysics, we use diagonal as well as non-diagonal tetrad fields. By considering the conformal Killing vectors along with the MIT bag model, the interior solutions of the field equations corresponding to the linear f (T ,) = α T (r) + β (r) + ϕ model (in which α , β are the constants and ϕ indicates the cosmological constant) are calculated. The feasibility of the obtained solutions is confirmed by implementing several physical tests. The model parameters are constrained subject to the existence and stability of the quark star models. We formulate the energy constraints, stability equations, mass function, compactness and redshift factor, and present the graphical analysis of all physical quantities. It is found that the derived solutions for both diagonal and non-diagonal tetrad exhibit well-behaved profiles in the framework of modified teleparallel gravity. [ABSTRACT FROM AUTHOR]
