Evaluating the Plausible Range of N2O Biosignatures on Exo-Earths: An Integrated Biogeochemical, Photochemical, and Spectral Modeling Approach
Edward W. Schwieterman, Stephanie L. Olson, Daria Pidhorodetska +7
Nitrous oxide (N2O) -- a product of microbial nitrogen metabolism -- is a compelling exoplanet biosignature gas with distinctive spectral features in the near- and mid-infrared, an…
Community Report from the Biosignatures Standards of Evidence Workshop
Victoria Meadows, Heather Graham, Victor Abrahamsson +72
The search for life beyond the Earth is the overarching goal of the NASA Astrobiology Program, and it underpins the science of missions that explore the environments of Solar Syste…
Earth as an Exoplanet. II. Earth's Time-variable Thermal Emission and Its Atmospheric Seasonality of Bioindicators
Jean-Noel Mettler, Sascha P. Quanz, Ravit Helled +2
We assess the dependence of Earth's disk-integrated mid-infrared thermal emission spectrum on observation geometries and investigate which and how spectral features are impacted by…
The Effect of Ocean Salinity on Climate and Its Implications for Earth's Habitability
Stephanie L. Olson, Malte F. Jansen, Dorian S. Abbot +2
The influence of atmospheric composition on the climates of present-day and early Earth has been studied extensively, but the role of ocean composition has received less attention.…
Moderately High Obliquity Promotes Biospheric Oxygenation
Megan N. Barnett, Stephanie L. Olson
Planetary obliquity is a first order control on planetary climate and seasonal contrast, which has a number of cascading consequences for life. How moderately high obliquity (obliq…
