Water-rich formation produces CH4- and CO2-rich atmospheres while water-poor formation produces carbon-depleted ones, with soot boosting methane; the H2O/CH4-MMW plane diagnoses formation environment for JWST targets.
Coupling Bern formation models with extended chemical equilibrium including S and N shows equilibration depletes atmospheric nitrogen, shifts C/O higher outside the ice line, generates Si species, and leaves sulfur abundances weakly dependent on formation location.
Models coupling hydrogen-silicate-iron miscibility with atmospheric escape reproduce the observed mass-radius occurrence density of sub-Neptunes and super-Earths.

A New Global Chemical Equilibrium Code: Refractory Element Signatures in Super-Earths and Sub-Neptunes
An open-source GCE code with a 100x faster solver demonstrates that refractory ratios Mg/Si and Fe/Si control carbon partitioning and atmospheric properties in water-accreting sub-Neptunes.

Atmospheric diversity of sub-Neptunes from formation with rock, water, and soot
Water-rich formation produces CH4- and CO2-rich atmospheres while water-poor formation produces carbon-depleted ones, with soot boosting methane; the H2O/CH4-MMW plane diagnoses formation environment for JWST targets.

The Role of Formation Location in Shaping Sulfur-, Nitrogen-, and Carbon-Bearing Species in Super-Earth and Sub-Neptune Atmospheres
Coupling Bern formation models with extended chemical equilibrium including S and N shows equilibration depletes atmospheric nitrogen, shifts C/O higher outside the ice line, generates Si species, and leaves sulfur abundances weakly dependent on formation location.
