Abstract
There are a number of different theories which tend to explain the concept of universe’s accelerated expansion. Among these theories, modified gravity is the most promising one. This paper elaborates matter distribution along with different characteristics of anisotropic compact stars in [Formula: see text] gravity background. Specifically, to profoundly understand physical behavior of the compact stars, we considered six compact stars, namely: Her X-1 ([Formula: see text]), SAXJ1808.4-3658 ([Formula: see text]), 4U1820-30 ([Formula: see text]), PSR J 1614 2230 ([Formula: see text]), VELA X-1 ([Formula: see text]) and Cen X-3 ([Formula: see text]) and calculated the corresponding quantities such as energy density ([Formula: see text]), radial pressure ([Formula: see text]) and tangential pressure ([Formula: see text]) using three distinct models of [Formula: see text] gravity. For simplicity, [Formula: see text] gravity is divided into two parts as: [Formula: see text]. The first part [Formula: see text] is considered Hu–Sawicki like model, while the second part [Formula: see text] is considered logarithmic like for Model 1 and power law like for Model 2 and Model 3. Predominantly, measurements of anisotropy, the energy conditions (ECs) and stability aspects of models for considered compacts stars are presented using graphical techniques. Furthermore, we also established that for the [Formula: see text] model parameter ([Formula: see text]), all the six stars show conventional behavior.
