Tidal deformability of a superfluid neutron star

Title: Tidal deformability of a superfluid neutron star

Abstract: In this work, we study the effect of superfluidity on the tidal response of a nonrotating neutron star.  This is done in a macroscopic two-fluid framework with entrainment effect where we take the neutron superfluid as one fluid and the other fluid is comprised of protons and electrons, making it a charge neutral fluid. We use a relativistic mean field model for the equation of state of the neutron star matter. Finally, we investigate the possibility of probing such exotic phase of matter through the Love numbers.
