Hydrodynamic escape from the proto-lunar disk and the origin of the Earth-Moon volatile dichotomy
The episode discusses a paper by Kaveh Pahlevana et al. that proposes hydrodynamic escape from the proto-lunar disk as the cause of Earth-Moon volatile depletion. The hosts explain how this fluid dynamics model connects high-temperature processes to chemical differences between Earth and the Moon, suggesting that an inflated hydrogen atmosphere in the proto-lunar disk was prone to ejecting volatiles.
