Statistical Geochemical Constraints On present-day Water Outgassing As A Source Of Secondary Atmospheres On The TRAPPIST-1 Exoplanets
The TRAPPIST-1 planetary system is observationally favorable for studying if planets orbiting M stars can retain atmospheres and host habitable conditions. Recent JWST secondary eclipse observations of TRAPPIST-1 c rule […]

Constraining Time Variations in Enceladus’ Water-Vapor Plume With Near-Infrared Spectra from Cassini-VIMS
Water vapor produces a series of diagnostic emission lines in the near infrared between 2.60 and 2.75 microns. The Visual and Infrared Mapping Spectrometer (VIMS) onboard the Cassini spacecraft detected […]
