Description:
At R10 km-deep hydrogen-dominated atmospheres. Thus, sub-Neptunes are mostly magma by mass and mostly atmosphere by volume. The most significant feature of the sub-Neptune planet population is the sharp drop-off in exoplanet abundance at ~3× Earth’s radius. We report results of recent research on magma-atmosphere interaction that explains this feature as due to dissolution of the atmosphere into the magma. Magma-atmosphere interaction contributes to the radius valley, but a gas loss proce
