| Abstract | |
In 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 Lambda(1.4) and on the Lambda(1) x Lambda(2) region. We also found a clear linear correlation between Lambda(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. (AU) | |
