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 ($J_0$), 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
$Lambda_1timesLambda_2$ 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.
