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…

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…
