  • In this paper, we have investigated the structural properties of rotating neutron stars using the numerical RNS code and equations of state which have been calculated within the lowest order constrained variational (LOCV) approach. In order to calculate the equation of state of nuclear matter, we have used UV 14+TNI and AV 18potentials. We have computed the maximum mass of the neutron star and the corresponding equatorial radius at different angular velocities. We have also computed the structural properties of Keplerian rotating neutron stars for the maximum mass configuration, M K, R K, f Kand j max.
