Tides in merging neutron stars: Consistency of the GW170817 event with experimental data on finite nuclei

The harmony of the nuclear equation of state (EoS) deduced from the GW170817 based tidal deformability with the one obtained from empirical data on microscopic nuclei is examined. It is found that suitably chosen experimental data on isoscalar and isovector sensitive nuclear observables complemented with the observed maximum neutron star mass constrain the EoS which displays a very good congruence with the GW170817 inspired one. The giant resonances in nuclei are found to be instrumental in limiting the tidal deformability parameter and the radius of neutron star in narrower bounds. The value of the canonical tidal deformability $\Lambda_{1.4}$ comes out to be $267\pm144$ and that of the radius $R_{1.4}$ is $11.6\pm1.0$ km.
