I work together with Jan Steinhoff on an effective field theoretical description of the tidal dynamics during the inspiral of binary neutron star systems. Binary systems containing neutron stars exhibit features deviating from the inspiral of binary black hole systems due to the deformability of the extended matter distributions in neutron stars. My current work focuses on the development and classification of gravitoelectric terms in the effective action of neutron star tidal dynamics in terms of their multipolar excitations and spin in the post-Newtonian (PN) limit. The precise calculation of these multipolar excitations and their effect on the waveforms of NS-NS gravitational waves may be useful in understanding the precise nature of neutron stars and gravity as a whole.
