Abstract
The aim of this paper is to investigate modified f(R, ϕ) theory of gravity, where R and ϕ represent the Ricci scalar and scalar potential respectively. Specifically, we take the spherically symmetric spacetime to discuss the possible emergence of compact stars. We study the physical behavior of compact stars by considering 4U 1820-30, SAX J 1808-3658 and Her X1, which are three popular models of compact stars. The graphical analysis of energy density, radial pressure, tangential pressure, energy conditions as well as stability of compact stars has been shown. It is concluded that behavior of these three stars is usual for f(R, ϕ) gravity models with some specific choices of model parameters.
