Abstract |
Coalescing binaries are among the most promising sources of gravitational waves for the new generation of terrestrial and space interferometers. Moreover they have been suggested as a possible explanation of short gamma-ray burst. Tidal interactions occurring in the last phases of these systems, can cause the neutron star disruption and are equation of state dependent: detection of the emitted gravitational signal may hence provide useful information on the stellar internal structure. In this talk we present a new semi-analytical approach to describe tidal interactions in black hole-neutron star or neutron star-neutron star binaries, based on the post-Newtonian expansion and the Affine approximation. We show how this model reproduces fully relativistic simulations and allows to derive the neutron star deformation properties. |
