  "abstract": "This study deals with the Riemann solutions of the isentropic Cargo-LeRoux system of conservation laws along with an extended Chaplygin fluid model and a generalized equation of state that captures nonlinear compressibility and non-ideal fluid behavior. It is shown that in the vanishing pressure limiting case, the Riemann solution yields a delta shock and a vacuum state. Delta shocks form when mass concentrates due to vanishing pressure, while vacuum states emerge in the rarefaction-dominated regions. These wave patterns are crucial in modeling real-world problems like discontinuous and multi-phase astrophysical fluid flows, underwater explosions, and combustion fronts.",
