Abstract
In this paper, we study the existence of strange star in the background of f(T) modified gravity where T is a scalar torsion. In KB metric space, we derive the equations of motion using anisotropic property within the spherically strange star with modified Chaplygin gas in the framework of modified f(T) gravity. Then we obtain many physical quantities to describe the physical status such as anisotropic behavior, energy conditions, and stability. By the matching condition, we calculate the unknown parameters to evaluate the numerical values of mass, surface redshift, etc., from our model to make comparison with the observational data.
Highlights
IntroductionCosmic acceleration is an interesting discovery. The observation of type Ia supernovae (SNeIa) together with the cosmic microwave background (CMB), large scale structure surveys (LSS), and Wilkinson Microwave Anisotropy Probe (WMAP) [1,2,3,4] ensures the presence of an exotic energy component dominating our universe which is entitled as dark energy (DE) having equation of state p = wρ with strong negative pressure

Summary
Cosmic acceleration is an interesting discovery. The observation of type Ia supernovae (SNeIa) together with the cosmic microwave background (CMB), large scale structure surveys (LSS), and Wilkinson Microwave Anisotropy Probe (WMAP) [1,2,3,4] ensures the presence of an exotic energy component dominating our universe which is entitled as dark energy (DE) having equation of state p = wρ with strong negative pressure. Abbas and his collaborations [46,47,48,49,50] have discussed the anisotropic compact star models in GR, f(R), f(G), and f(T) theories in diagonal tetrad case with Krori and Barua (KB) metric. Abbas et al [ ] have studied anisotropic strange star which corresponds to quintessence dark energy model with the help equation of state p = αρ, where 0 < α < 1. Our main motivation of this paper is to study the anisotropic strange star models in the framework of f(T) gravity with diagonal tetrad in presence of electric field and modified Chaplygin gas. In Section , we study anisotropic quintessence strange star in f(T) gravity with the help of modified Chaplygin gas.
