We discuss numerical general relativistic hydrodynamic simulations for close neutron star binary systems. The hydrodynamics and field equations are solved at each time slice with a spatial 3-metric chosen to be conformally flat. By using an adaptive mesh we are able to reliably numerically integrate many orbits of the binary system. The gravitational radiation signal is extracted via a multipole expansion to the l = 4 order including both mass and current moments and a correction for the slow motion approximation. We compute quasi-equilibrium circular orbit conditions for two equal-mass neutron stars as a function of total angular momentum from the post-Newtonian regime to near the last stable circular orbit. We have considered a variety of neutron star equations of state. From the angular momentum and power loss rate we reconstruct the gravitational wave form and find that there is a detectable equation of state dependence of the computed gravity-wave signal.
