| The detection of GW170817 coming from the coalescence of two neutron-stars allowed us, by combining the analytical models with the analysis of the signal, to constrain the equation of state (EOS) of neutron-stars. Some of them have already been discarded. The post-Newtonian formalism played a crucial role in the extraction of the signal but more precision on the waveform modelling finite-size effects is required, especially for Einstein Telescope. I will present the recent work done to increase the precision on the post-Newtonian waveform of tidal effects in a binary system in order to better constrain the EOS of neutron-stars. |
