Noble Gas Depletion On Titan: Clathrate Sequestration During The Open Ocean Phase
A plausible explanation for the absence of primordial argon, krypton, and xenon in Titan’s current atmosphere is that these gases were sequestered in clathrate hydrates during Titan’s “open-ocean” phase.

Insights on the Formation Conditions of Uranus and Neptune from their Deep Elemental Compositions
This study, placed in the context of the preparation for the Uranus Orbiter Probe mission, aims to predict the bulk volatile compositions of Uranus and Neptune. Using a protoplanetary disk […]
