My 1st first-author paper has been submitted to ApJL and is available on arXiv! We found that elevated water vapor abundances in Mars-like exoplanet atmospheres suppress abiotic oxygen accumulation via CO2 photolysis by an order of magnitude relative to past studies. 🧪🔭🪐 arxiv.org/abs/2603.11017

Oxygenated False Positive Biosignatures in Mars-like Exoplanet Atmospheres

Oxygen is a well-studied biosignature. Studying potential abiotic pathways for O2 build-up in exoplanet atmospheres is essential for evaluating whether the detection of O2 would constitute a biosignat...
