Equifinality of Venus-like CO Atmospheres
Tereza Constantinou, Oliver Shorttle, Harrison Nicholls
While Earth locks much of its carbon in its crust as carbonates, Venus retains a comparable carbon inventory almost entirely in its atmosphere as CO. On Earth, the geological c…
Comparative biosignatures with systemic retrievals
Tereza Constantinou, Oliver Shorttle, Miles Cranmer +1
The discovery of inhabited exoplanets hinges on identifying biosignature gases. JWST can reveal biosignature gases, though current discoveries have yet to evidence life. The centra…
Powerful lightning on Venus constrained by atmospheric NO
Tereza Constantinou, Oliver Shorttle, Paul B. Rimmer
Signs of lightning on Venus have long been sought, including by space missions and ground-based telescopes searching for optical flashes, plasma waves, or radio signatures. These e…
Prediction of sulphate hazes in the lower Venus atmosphere
Peter Woitke, Manuel Scherf, Christiane Helling +8
We study the amount, size distribution and material composition of (sub-)mic aerosol particles in the lower Venus atmosphere < 50 km. Our GGchem phase-equilibrium model predicts me…
Abiotic Ozone in the Observable Atmospheres of Venus and Venus-like Exoplanets
Robb Calder, Oliver Shorttle, Sean Jordan +2
Ozone is a potential biosignature and disambuguator between Earth-like and Venus-like exoplanets due to its association on Earth with photosynthetically produced oxygen (O). Ho…
A dry Venusian interior constrained by atmospheric chemistry
Tereza Constantinou, Oliver Shorttle, Paul B. Rimmer
Venus's climatic history provides powerful constraint on the location of the inner-edge of the liquid-water habitable zone. However, two very different histories of water on Venus…
