Unusually Hot Interiors Could Reconcile the Missing Methane Problem for Warm-to-Hot Exoplanets with Hydrogen Atmospheres
Xinting Yu, Christopher R. Glein, Daniel P. Thorngren +1
JWST is revolutionizing the field of exoplanet atmospheres by delivering unprecedented spectroscopic constraints on their chemical compositions. It has provided tight constraints o…
Phosphates Reveal High pH Ocean Water on Enceladus
Christopher R. Glein, Ngoc Truong
Enceladus offers our best opportunity for exploring the chemistry of an ocean on another world. Here, we perform geochemical modeling to show how the distribution of phosphate spec…
Volatile-rich Sub-Neptunes as Hydrothermal Worlds: The Case of K2-18 b
Cindy N. Luu, Xinting Yu, Christopher R. Glein +8
Temperate exoplanets between the sizes of Earth and Neptune, known as "sub-Neptunes", have emerged as intriguing targets for astrobiology. It is unknown whether these planets resem…
The role of ammonia in the distribution of volatiles in the primordial hydrosphere of Europa
Alizée Amsler Moulanier, Olivier Mousis, Alexis Bouquet +1
The presence of a hydrosphere on Europa raises questions about its habitability, and studies of its volatile inventory can provide insight into its formation process. Different sce…
