Smaller Than Earth Habitability Model (STEHM): The Lower Size Limit for Atmosphere Retention in the Habitable Zone
Planets of 0.8 Earth radii and larger retain atmospheres over multi-gigayear timescales in the habitable zone under default stagnant-lid conditions, while smaller ones lose them, with initial carbon inventory as the dominant control.
