Young sub-Neptunes transition from core-powered bolometric escape to photoevaporative escape at smaller radii for lower-mass and more irradiated planets, with self-consistent simulations yielding combined mass-loss rates and analytic transition scalings.
Coupled thermal-chemical models indicate that sub-Neptunes formed outside the water-ice line exhibit high atmospheric CH4, H2O, and C/O ratios while those formed inside show suppressed CH4 and low C/O.
Water- and metal-rich atmospheres on compact hot mini-Neptunes lose mass more slowly than H/He cases at high enrichment levels due to enhanced cooling and higher mean molecular weight.
Interior structure models show 28 of 34 cold super-puffs are consistent with core accretion while six require non-standard explanations such as impacts or exo-rings.
Clouds drive over 1000 K heating at depth in sub-Neptune atmospheres, producing molten mantle interfaces for most planets in the sample and increasing abundances of O2, SiH4, and SiO by at least 36 percent.
