Inferring chemical disequilibrium biosignatures for Proterozoic Earth-like exoplanets
Nature Astronomy, Published online: 22 January 2024; doi:10.1038/s41550-023-02145-z Chemical disequilibrium is a known biosignature, and it is important to determine the conditions for its remote detection. A thermodynamical model coupled with atmospheric retrieval shows that a disequilibrium can be inferred
