Relative entropy shift applied by the Mazevet et al. (2019) correction (Eq. (17)) across the water phase diagram in plog10 T, log10 Pq space. The colormap is logarithmic between 10´3 and 10, with the upper bound saturating along a narrow ridge where the aqua baseline entropy nearly vanishes. Solid white lines mark the phase boundaries of the underlying aqua table; labels identify the fields of ices, liquid, vapor, and supercritical water. Dashed lime contours with inline labels mark the analytic gate w7 that selects where the patch is applied: w7“0 outside the patch (no shift) and w7“1 inside its core (full correction). The figure shows that the correction is concentrated in a localized strip of the supercritical regime between ice X and the Brown (2018) fluid, leaving the rest of the aqua table untouched. -- astro-ph.EP

PALEOS: Multiphase Equations of State and Mass-Radius Relations for Exoplanet Interiors

by Keith CowingMay 7, 2026May 7, 2026

Modeling the interior of a rocky or water-rich exoplanet is a thermodynamic closure problem: every layer’s density, temperature gradient, and phase must follow from an equation of state (EoS) that […]
