Description

When in dynamical capture binaries, neutron stars will necessarily undergo dynamical tidal interactions, due to the tidal field becoming sharply peaked around pericenter passage. This results in two effects: 1) a slow evolution of the neutron star's tides, proportional to the perturbing tidal field, and 2) the excitation of fluid oscillation modes inside of the star. Using analytic techniques, I will discuss the impact of these two effects on the gravitational wave emitted by dynamical capture binaries within the effective fly-by (EFB) framework, specifically focusing on the change in burst arrival times.
