  The role of the symmetry energy and the neutron-matter stiffness on the tidal
deformability of a cold nonaccreted neutron star is studied using a set of
unified equations of state. Based on the nuclear energy-density functional
theory, these equations of state provide a thermodynamically consistent
treatment of all regions of the star and were calculated using functionals that
were precision fitted to experimental and theoretical nuclear data. Predictions
are compared to constraints inferred from the recent detection of the
gravitational-wave signal GW170817 from a binary neutron-star merger and from
observations of the electromagnetic counterparts.
