Abstract

We use the post-Newtonian-Affine model to assess the validity of the\nadiabatic approximation in modeling tidal effects in the phase evolution of\ncompact binary systems. We compute the dynamical evolution of the tidal tensor,\nwhich we estimate at the 2 PN order, and of the quadrupole tensor, finding that\ntheir ratio, i.e. the tidal deformability, increases in the last phases of the\ninspiral. We derive the gravitational wave phase corrections due to this\nphenomenon and quantify how they affect gravitational wave detectability.\n
