Last orbits of binary neutron stars and binary black holes — •Eric Gourgoulhon — Laboratoire de l’Univers et de ses Théories (LUTH), Observatoire de Paris, F-92195 Meudon

I will present numerical results of computations of quasi-equilibrium configurations of close binary systems within general relativity, under an approximation which amounts to solve five of the ten Einstein equations. These configurations represent the last stages of the evolution of a binary system driven by the reaction to gravitational radiation, prior to the final merger. They constitute promising sources for the gravitational wave detectors LIGO, GEO600 and VIRGO currently coming on line.
