Abstract: We discuss the application of van der Waals-type models in describing hadronic systems in extreme conditions, such as the high density regime. For this purpose, we modify the attractive and repulsive parts of the nucleon–nucleon interaction by making them 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 a real gas model. The phenomenology of short-range correlations (SRCs) are also taken into account. The parametrizations of the resulting models 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 K0 = (240 ± 20) MeV. In the context of stellar matter, our findings point out a good agreement 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 mission.
