Carbon-rich Sub-Neptune Interiors Are Compatible with JWST Observations

Many possible interior compositions exist for sub-Neptunes: ice-poor, ice-rich, and water-dominated interiors can all match the measured masses and radii. Motivated by a recent theory of carbon-rich planet formation outside the refractory organic carbon “soot line” and observations of carbon-rich pr...
