Geoscience and the Search for Life Beyond the Solar System
Rory Barnes, Anat Shahar, Cayman Unterborn +11
How can scientists conclude with high confidence that an exoplanet hosts life? As telescopes come on line over the next 20 years that can directly observe photons from terrestrial…
Disequilibrium biosignatures over Earth history and implications for detecting exoplanet life
Joshua Krissansen-Totton, Stephanie Olson, David C. Catling
Chemical disequilibrium in planetary atmospheres has been proposed as a generalized method for detecting life on exoplanets through remote spectroscopy. Among solar system planets…
Life Beyond the Solar System: Remotely Detectable Biosignatures
Shawn Domagal-Goldman, Nancy Y. Kiang, Niki Parenteau +38
For the first time in human history, we will soon be able to apply the scientific method to the question "Are We Alone?" The rapid advance of exoplanet discovery, planetary systems…
A warm or a cold early Earth? New insights from a 3-D climate-carbon model
Benjamin Charnay, Guillaume Le Hir, Frédéric Fluteau +2
Oxygen isotopes in marine cherts have been used to infer hot oceans during the Archean with temperatures between 60°C (333 K) and 80°C (353 K). Such climates are challenging for th…
Rocky Worlds Limited to ~1.8 Earth Radii by Atmospheric Escape During a Star's Extreme UV Saturation
Owen Lehmer, David Catling
Recent observations and analysis of low mass (<10), exoplanets have found that rocky planets only have radii up to 1.5-2. Two general hypotheses exist for t…
An Analytic Radiative-Convective Model for Planetary Atmospheres
Tyler D. Robinson, David C. Catling
We present an analytic 1-D radiative-convective model of the thermal structure of planetary atmospheres. Our model assumes that thermal radiative transfer is gray and can be repres…
