This study introduces a phonon-based theoretical framework for liquids, marking a major step toward a universal equation of state with broad implications across physics, chemistry and engineering ...

Until now, scientists assumed f2 could stand in for a neutron star's radius because the two values are often linked to each other. But that is not always the case, the new research determined.

Equations 1-4 (see Equation box) show the MMM equation of state. 5 6 Click here to enlarge image This equation was previously used for PVT and VLE calculations of pure and mixed fluids.
