We report the results of three-dimensional Newtonian calculations of neutron-star binary coalescence using smooth particle hydrodynamics (SPH). Using a relaxation technique, we construct hydrostatic equilibrium models of close neutron-star binaries in synchronized circular orbits. We use a simple polytropic equation of state with Γ=2 to represent cold nuclear matter, and we assume that the mass ratio q=1, as observed in all known neutron-star binary systems. Using SPH, we study the dynamical stability of these hydrostatic equilibrium models
