<jats:title>Abstract</jats:title>
<jats:p>The Tolman-Oppenheimer-Volkoff (TOV) equation determines the structure of a spherically symmetric body of isotropic material in equilibrium, in general relativity (GR). It is widely used in the study of properties of compact stars. In case of charged compact stars, an extended TOV equation was found first by Bekenstein in 1971.</jats:p>
<jats:p>We aim to use, the <jats:italic>f</jats:italic> (<jats:italic>R</jats:italic> ) theory of gravity, one among several proposed extended theories of gravity to find an equivalent equation to TOV equation, and use it to study electrically charged compact stars. We assume that the charge density is proportional to the energy density of the star and we choose the polytropic equation of state to describe the state of the charged star. We perform a detailed numerical study using Maple 2016, and our results are compared to those found in the literature in the framework of GR.</jats:p> |
