Modeling pN2 through Geological Time: Implications for Planetary Climates and Atmospheric Biosignatures
E. E. Stüeken, M. A. Kipp, M. C. Koehler +3
Nitrogen is a major nutrient for all life on Earth and could plausibly play a similar role in extraterrestrial biospheres. The major reservoir of nitrogen at Earth's surface is atm…
The Pale Orange Dot: The Spectrum and Habitability of Hazy Archean Earth
Giada Arney, Shawn D. Domagal-Goldman, Victoria S. Meadows +6
Recognizing whether a planet can support life is a primary goal of future exoplanet spectral characterization missions, but past research on habitability assessment has largely ign…
The Habitability of Proxima Centauri b: II: Environmental States and Observational Discriminants
Victoria S. Meadows, Giada N. Arney, Edward W. Schwieterman +11
Proxima Centauri b provides an unprecedented opportunity to understand the evolution and nature of terrestrial planets orbiting M dwarfs. Although Proxima Cen b orbits within its s…
The Habitability of Proxima Centauri b I: Evolutionary Scenarios
Rory Barnes, Russell Deitrick, Rodrigo Luger +14
We analyze the evolution of the potentially habitable planet Proxima Centauri b to identify environmental factors that affect its long-term habitability. We consider physical proce…
Identifying Planetary Biosignature Impostors: Spectral Features of CO and O4 Resulting from Abiotic O2/O3 Production
Edward W. Schwieterman, Victoria S. Meadows, Shawn D. Domagal-Goldman +6
O2 and O3 have been long considered the most robust individual biosignature gases in a planetary atmosphere, yet multiple mechanisms that may produce them in the absence of life ha…
Is the Pale Blue Dot unique? Optimized photometric bands for identifying Earth-like exoplanets
Joshua Krissansen-Totton, Edward W. Schwieterman, Benjamin Charnay +4
The next generation of ground and space-based telescopes will image habitable planets around nearby stars. A growing literature describes how to characterize such planets with spec…
