Abstract

To obtain analytically relativistic quintessence anisotropic spherical solutions in the f(T)paradigm is the primary objective of this paper.To do this,the pressure anisotropy condition is imposed,and we employ a metric potential of the Tolman-Kuchowicz(TK)type.We also suppose that our current model incorporates a quintessence field characterized by a parameter ωq,in addition to the anisotropic matter distribution.In the presence of the parameter α,the field equations are modified by the choice of thef(T)function.Thef(T)gravity parameter α adds new components to the basic physical characteristics,such as density,pressure,subliminal sound velocity,surface redshift,etc,of the present model.By selecting the compact star Her X-1 and varying α from 0.5 to 2.5,we examined all the physical characteristics of the model parameter of the configuration.The graphical process demonstrates that a more compact item is produced with greater values of α.The hydrostatic equilibrium condition of the model is discussed,as well as the mass-radius relationship for our current model is obtained.
