Centrifugal Forces and Optical Geometry in Neutron Stars

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 behavior is here graphically depicted for realistic neutron stars, shown to be quite different from the non-relativistic case and to depend on the particular form of the equation of state. This revised version was published online in July 2006 with corrections to the Cover Date.
