Earth is expected to have acquired a reduced proto-atmosphere enriched in H2 and CH4 through the accretion of building blocks that contain metallic Fe and/or the gravitational trapping of surrounding […]

Biogenic Sulfur Gases As Biosignatures On Temperate Sub-Neptune Waterworlds
Theoretical predictions and observational data indicate a class of sub-Neptune exoplanets may have water-rich interiors covered by hydrogen-dominated atmospheres. Provided suitable climate conditions, such planets could host surface liquid oceans.
Signatures Of X-ray Dominated Chemistry In The Spectra Of Exoplanetary Atmospheres
High-energy radiation from stars impacts planetary atmospheres deeply affecting their chemistry, providing departures from chemical equilibrium.
3D Simulations Of The Archean Earth Including Photochemical Haze Profiles
We present results from 3D simulations of the Archean Earth including a prescribed (non-interactive) spherical haze generated through a 1D photochemical model.
Low Pressure EUV Photochemical Experiments: Insight on the Ion-Chemistry Occurring in Titan's Atmosphere
Thanks to the Cassini spacecraft onboard instruments, it has been known that Titan’s ionospheric chemistry is complex and the molecular growth is initiated through the photolysis of the most abundant […]
