Fully fluorinated non-carbon compounds NF3 and SF6 as ideal technosignature gases

Kavli Affiliate: Sara Seager | First 5 Authors: Sara Seager, Janusz J. Petkowski, Jingcheng Huang, Zhuchang Zhan, Sai Ravela | Summary: Waste gas products from technological civilizations may accumulate in an exoplanet atmosphere to detectable levels. We propose nitrogen trifluoride (NF3) and sulfur hexafluoride (SF6) as ideal technosignature gases. Earth life avoids producing or using […]
