The peak absorbance wavelength of photosynthetic pigments around other stars from spectral optimization
Owen R. Lehmer, David C. Catling, Mary N. Parenteau +2
In the search for life on other planets, the presence of photosynthetic vegetation may be detectable from the colors of light it reflects. On the modern Earth, this spectral reflec…
Carbonate-Silicate Cycle Predictions of Earth-like Planetary Climates and Testing the Habitable Zone Concept
Owen R. Lehmer, David C. Catling, Joshua Krissansen-Totton
In the conventional habitable zone (HZ) concept, a CO-HO greenhouse maintains surface liquid water. Through the water-mediated carbonate-silicate weathering cycle, atmosp…
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…
The longevity of water ice on Ganymedes and Europas around migrated giant planets
Owen R. Lehmer, David C. Catling, Kevin J. Zahnle
The gas giant planets in the Solar System have a retinue of icy moons, and we expect giant exoplanets to have similar satellite systems. If a Jupiter-like planet were to migrate to…
