Description
Since the first detection of a binary neutron star system, GW170817, the number of compact binary systems involving neutron stars observed by the LVK network has continued to grow. The tidal deformability of neutron stars influences the gravitational waves emitted during inspiral phase, making these effects observable. Consequently, waveform models used to analyze such signals must incorporate tidal interactions. In these models, the inspiral phase is typically described using post-Newtonian theory. Accurately modeling neutron star deformability is therefore essential. In this talk, I will present the post-Newtonian formalism, with a focus on its application to the effective description of tidal effects, and discuss recent developments in the field.
