Hydrogenated atmospheres of lava planets: Atmospheric structure and emission spectra

A Falco, P Tremblin, S Charnoz, RJ Ridgway… - Astronomy & …, 2024 - aanda.org
Ultra-hot rocky super-Earths are thought to be sufficiently irradiated by their host star to melt
their surface and allow for long-lasting magma oceans as a result. A number of processes …

Toward a Self-consistent Evaluation of Gas Dwarf Scenarios for Temperate Sub-Neptunes

FE Rigby, L Pica-Ciamarra, M Holmberg… - The Astrophysical …, 2024 - iopscience.iop.org
The recent JWST detections of carbon-bearing molecules in a habitable-zone sub-Neptune
