On a newly formed rocky planet, a magma ocean keeps breathing out gas while the young star strips gas away. This study adds atmospheric escape to PROTEUS and follows that contest across many orbits, interior chemistries, and starting volatile budgets: escape weakens the atmosphere's greenhouse blanket, so the magma ocean freezes sooner, and the surviving gas ends up chemically sorted, because some species dissolve into magma more readily than others. Earth-mass planets keep their atmospheres as long as losses stay moderate, with outcomes spanning bare rock to thick hydrogen- or sulfur-rich envelopes.

This study shows that the chemistry of a rocky super-Earth's molten interior can make its atmosphere puff back up late in the planet's life, temporarily lowering its bulk density by as much as 60%. Planets with chemically reduced interiors first build carbon-rich atmospheres and later switch to hydrogen-rich ones, as gas escapes to space while fresh hydrogen is released from the magma ocean below, whereas more oxidised, Earth-like planets simply shrink over time. Measuring these density differences across many close-in super-Earths could help trace the hidden chemistry of planetary interiors and the conditions under which these worlds formed.

Oxygen fugacity controls how a rocky mantle melts, yet most magma-ocean models assume Earth-like oxidised conditions. Using PROTEUS with experimentally derived, redox-dependent melting curves, this study finds that a planet's volatile inventory and surface oxygen fugacity are the primary controls on its thermal state, with the melting curve a secondary modulation. Reduced mantles produce massive H2-CO atmospheres and oxidised mantles thinner H2O-CO2 envelopes, giving distinct, JWST-testable spectral predictions for close-in super-Earths such as GJ 1132 b.
