  We perform an improvement in a van der Waals-type model by including it
effects of short-range correlations (SRC). Attractive and repulsive parts of
the nucleon-nucleon interaction are assumed to be density-dependent functions,
more specifically, we adopt the Carnahan-Starling (CS) method for the latter,
and a suitable expression for the former in order to reproduce the structure of
the Clausius (C) real gas model. The parametrizations of the resulting model,
named as CCS-SRC model, are shown to be capable of reproducing the flow
constraint at the high-density regime of symmetric nuclear matter for
incompressibility values inside the range of $K_0=(240\pm 20)$ MeV. In the
context of stellar matter, our findings point out a good agreement of the
CCS-SRC model with recent astrophysical observational data, namely, mass-radius
contours and dimensionless tidal deformability regions and values, coming from
gravitational waves data related to the GW170817 and GW190425 events, and from
the NASA's Neutron star Interior Composition Explorer (NICER) mission.
Furthermore, the values for the symmetry energy slope of the model ($L_0$) are
in agreement with a recent range found for this quantity, claimed to be
consistent with results reported by the updated lead radius experiment (PREX-2)
collaboration. In this case, higher values of $L_0$ are favored, while the
opposite scenario does not allow simultaneous compatibility between the model
and the astrophysical data.
