Abstract
In this paper centrifugal forces and the geometry of light ray trajectories in neutron stars are discussed. The general behavior of centrifugal forces and angular momentum transfer is closely linked to the geometry of photon trajectories, such a behaviour is here graphically depicted for realistic n eutron stars, shown to be quite different from the non-relativistic case an d to depend on the particular form of the equation of state.
