Abstract

We have obtained the Love number and corresponding tidal deformabilities (\mathrm\ensuremathΛ) associated with the relativistic mean-field parametrizations shown to be consistent (CRMF) with the nuclear matter, pure neutron matter, symmetry energy, and its derivatives [Dutra et al., Phys. Rev. C 90, 055203 (2014)]. Our results show that CRMF models present very good agreement with the recent data from binary neutron star merger event GW170817. They also confirm the strong correlation between \mathrm\ensuremathΛ_1.4 and the radius of canonical stars (R_1.4). When a recent GW170817 constraint on \mathrm\ensuremathΛ_1.4 and the corresponding radius R_1.4 is used, the majority of the models tested are shown to satisfy it.
