Venusian phosphine: a 'Wow!' signal in chemistry?
William Bains, Janusz J. Petkowski, Sara Seager +6
The potential detection of ppb levels phosphine (PH3) in the clouds of Venus through millimeter-wavelength astronomical observations is extremely surprising as PH3 is an unexpected…
Assessment of Ammonia as a Biosignature Gas in Exoplanet Atmospheres
Jingcheng Huang, Sara Seager, Janusz J. Petkowski +2
Ammonia (NH3) in a terrestrial planet atmosphere is generally a good biosignature gas, primarily because terrestrial planets have no significant known abiotic NH3 source. The condi…
Assessment of Isoprene as a Possible Biosignature Gas in Exoplanets with Anoxic Atmospheres
Zhuchang Zhan, Sara Seager, Janusz Jurand Petkowski +4
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 i…
The TESS Objects of Interest Catalog from the TESS Prime Mission
Natalia M. Guerrero, S. Seager, Chelsea X. Huang +102
We present 2,241 exoplanet candidates identified with data from the Transiting Exoplanet Survey Satellite (TESS) during its two-year prime mission. We list these candidates in the…
Persistence of Flare-Driven Atmospheric Chemistry on Rocky Habitable Zone Worlds
Howard Chen, Zhuchang Zhan, Allison Youngblood +3
Low-mass stars show evidence of vigorous magnetic activity in the form of large flares and coronal mass ejections. Such space weather events may have important ramifications for th…
