Constraining Prebiotic Chemistry Through a Better Understanding of Earth's Earliest Environments
Timothy W. Lyons, Karyn Rogers, Ramanarayanan Krishnamurthy +5
Any search for present or past life beyond Earth should consider the initial processes and related environmental controls that might have led to its start. As on Earth, such an und…
Exogeoscience and Its Role in Characterizing Exoplanet Habitability and the Detectability of Life
Cayman T. Unterborn, Paul K. Byrne, Ariel D. Anbar +24
The search for exoplanetary life must encompass the complex geological processes reflected in an exoplanet's atmosphere, or we risk reporting false positive and false negative dete…
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…
Observational Constraints on the Great Filter
Jacob Haqq-Misra, Ravi Kumar Kopparapu, Edward Schwieterman
The search for spectroscopic biosignatures with the next-generation of space telescopes could provide observational constraints on the abundance of exoplanets with signs of life. A…
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.,…
