Abstract

This study aims to discuss anisotropic solutions that are spherically symmetric in the quintessence field,which de-scribe compact stellar objects in the modified Rastall teleparallel theory of gravity.To achieve this goal,the Krori and Barua arrangement for spherically symmetric components of the line element is incorporated.We explore the field equations by selecting appropriate off-diagonal tetrad fields.Born-Infeld function of torsion f(T)=β √λT+1-1 and power law form h(T)=δTn are used.The Born-Infeld gravity was the first modified teleparallel gravity to discuss inflation.We use the linear equation of state pr=ξρ to separate the quintessence density.After obtaining the field equations,we investigate different physical parameters that demonstrate the stability and physical acceptability of the stellar models.We use obser-vational data,such as the mass and radius of the compact star candidates PSRJ 1416-2230,Cen X-3,& 4U 1820-30,to ensure the physical plausibility of our findings.
