Anisotropic strange quintessence stars in f(T) gravity

This paper deals with the new theoretical model of quintessence anisotropic star in f(T) theory of gravity. The equations of motion in f(T) theory with a static spherically symmetric spacetime in the presence of anisotropic fluid and quintessence field have been solved by using Krori-Barua metric. In this case, we have used the diagonal tetrad field that leads to a linear form f(T) function. We have determined that all the obtained solutions are free from central singularity and potentially stable. The values of the unknown constants existing in Krori and Barua metric have been calculated by using the observed values for mass of the different strange stars PSR J 1614-2230, SAXJ1808.4-3658(SS1), 4U1820-30, PSR J 1614-2230. The physical parameters (anisotropy, stability and redshift) of the stars have been investigated in detail. We have determined the constraint under which results of f(T), theory reduces to general relativity.
