Abstract

We have obtained the Love number and corresponding tidal deformabilites (Λ\Lambda) 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 Λ1.4\Lambda_{1.4} and the radius of canonical stars (R1.4R_{1.4}). When a recently GW170817 constraint on Λ1.4\Lambda_{1.4} and the corresponding radius R1.4R_{1.4} is used, the majority of the models tested are shown to satisfy it.
