Photochemistry of Anoxic Abiotic Habitable Planet Atmospheres: Impact of New HO Cross-Sections
Sukrit Ranjan, Edward W. Schwieterman, Chester Harman +4
We present a study of the photochemistry of abiotic habitable planets with anoxic CO-N atmospheres. Such worlds are representative of early Earth, Mars and Venus, and analo…
Warming Early Mars with Climate Cycling: The Effect of CO2-H2 Collision-induced Absorption
Benjamin P. C. Hayworth, Ravi Kumar Kopparapu, Jacob Haqq-Misra +5
Explaining the evidence for surface liquid water on early Mars has been a challenge for climate modelers, as the sun was ~30% less luminous during the late-Noachian. We propose tha…
TOI-1338: TESS' First Transiting Circumbinary Planet
Veselin B. Kostov, Jerome A. Orosz, Adina D. Feinstein +65
We report the detection of the first circumbinary planet found by TESS. The target, a known eclipsing binary, was observed in sectors 1 through 12 at 30-minute cadence and in secto…
Sensitive Probing of Exoplanetary Oxygen via Mid Infrared Collisional Absorption
Thomas J. Fauchez, Geronimo L. Villanueva, Edward W. Schwieterman +6
The collision-induced fundamental vibration-rotation band at 6.4 um is the most significant absorption feature from O2 in the infrared (Timofeyev and Tonkov, 1978; Rinslandet al.,…
