Descrição: dc.descriptionIn the present work, we investigate the effects of short-range correlations (SRC) on the dimensionless deformability of the binary neutron system related to the GW170817 event. We implemented phenomenological SRC in a relativistic mean-field model in which the bulk parameters, namely, incompressibility ( K 0 ), effective nucleon mass ratio ( m ∗ ), symmetry energy ( J ), and its slope ( L 0 ), are independently controlled. Our results point out that the SRC favor the model to pass through the constraints, established by the LIGO/Virgo Collaboration, on the values of Λ 1.4 and on the Λ 1 × Λ 2 region. We also found a clear linear correlation between Λ 1.4 with K 0 and L 0 (increasing dependence), and with m ∗ and J (decreasing dependence). Finally, we also obtained compatible numbers for R 1.4 (model with and without SRC) in comparison with recent data from the neutron star interior composition explorer mission.-
