Assessment of Isoprene as a Possible Biosignature Gas in Exoplanets with Anoxic Atmospheres

Research for possible biosignature gases on habitable exoplanet atmosphere is accelerating. We add isoprene, C5H8, to the roster of biosignature gases. We found that formation of isoprene geochemical formation is highly thermodynamically disfavored and has no known abiotic false positives. The isopr...
