Tidal effects in binary neutron star coalescence — •Sebastiano Bernuzzi — TPi, Jena, Germany

Gravitational waves from coalescing neutron stars carries unique information about the star's equation of state. An accurate theoretical modeling of these systems is of primary importance to extract robust data in a direct detection of gravitational waves.

I will present results about tidal effects in binary neutron star coalescence and their signature in gravitational radiation emitted. In particular, I will discuss the outcome of state-of-art numerical relativity simulations and their comparison with analytical approaches like post-Newtonian method and the effective-onde-body model.
