Rapidly rotating compact stars in Rastall’s gravity
F M da Silva, L C N Santos, C C Barros
Abstract
Abstract In this work we study rapidly rotating stars by considering the Rastall theory of gravity. We obtain and solve the equations by numerical methods for two usual parametrization of polytropic stars. Then the mass–radius relations, moments of inertia and other results of interest are obtained and compared with the ones for non-rotating stars.
