摘要：

The end state of a coalescing binary of compact objects depends strongly on the final total mass M and angular momentum J. Since gravitational radiation emission causes a slow evolution of the binary system through quasi-circular orbits down to the innermost stable one, in this paper we examine the corresponding behavior of the ratio J/M-2, which must be less than 1(G/c) or about 0.7(G/c) for the formation of a black hole or a neutron star, respectively. The results show cases for which, at the end of the inspiral phase, these conditions are not satisfied. The inclusion of spin effects leads us to a study of precession equations valid also for the calculation of gravitational waveforms.
