Abstract

The star rotation will undoubtedly affect the star's characteristics described by the hydrostatic equilibrium equation. The centrifugal force distorts the star's shape and modifies its equilibrium structure. The choice of the gravity model such as Eddington inspired Born Infeld theory of gravity will also affect the geometry properties of stars. In this case, it will change the corresponding Poisson's equations. So it is desirable to see the modification of hydrostatic equation of states of the non-relativistic rotating stellar object within Eddington inspired Born Infeld theory of gravity. Lane-Emden equations have been used to describe the mass-density distribution in the stars of polytropic equation state of the stars with and without rotation [4]. In this paper, we would like to derive analytically and numerically the modified Lame-Emden equations for rotating non-relativistic stars within Eddington inspired Born Infeld theory of gravity. In this study Eddington inspired Born Infeld theory of gravity will give contribution to make the differences in the geometry and mass of the star.
