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 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…
TOI 694 b and TIC 220568520 b: Two Low-Mass Companions Near the Hydrogen Burning Mass Limit Orbiting Sun-like Stars
Ismael Mireles, Avi Shporer, Nolan Grieves +40
We report the discovery of TOI 694 b and TIC 220568520 b, two low-mass stellar companions in eccentric orbits around metal-rich Sun-like stars, first detected by the Transiting Exo…
EX Draconis: Using Eclipses to Separate Outside-In and Inside-Out Outbursts
James M. C. Court, Simone Scaringi, Colin Littlefield +8
We present a study of the eclipses in the accreting white dwarf EX Dra during TESS Cycles 14 and 15. During both of the two outbursts present in this dataset, the eclipses undergo…
