The coalescence rate of two neutron stars (NS) is revisited. To estimate the number of bound NS-NS and the probability of their coalescence in a time scale τ, the galactic star formation history, directly derived from observations, and the evolution of massive stars are considered. The newly established galactic merging rate is (1.7±1.0) × 10-5yr-1, while the local merging rate, including the contribution of elliptical galaxies, is about a factor of two higher, 3.4 × 10-5yr-1. Using the present…

The recent discovery of the first four afterglows of short-hard gamma-ray bursts (SHBs) suggests that they typically result from long-lived progenitor systems. The most popular progenitor model

Binary Neutron Star Mergers

The quasi-equilibrium approximation has played a key role in developing understanding of the physics of binary coalescence and, in particular, of the orbital instability processes that can drive binaries to merger at the end of their lifetimes.
