Planetary Albedo Is Limited by the Above-cloud Atmosphere: Implications for Sub-Neptune Climates
Astrophysical JournalEnergy limits that delineate the “habitable zone” for exoplanets depend on a given exoplanet’s net planetary albedo (or “Bond albedo”). We here demonstrate that the planetary albedo of an observed exoplanet is limited by the above-cloud atmosphere—the ...

Seasonal Thaws under Mid- to Low-pressure Atmospheres on Early Mars
The Astrophysical Journal, 2023 Despite decades of scientific research on the subject, the climate of the first 1.5 Gyr of Mars' history has not been fully understood yet. Especially challenging is the need to reconcile the presence of liquid water for extended periods of time on the ...

Moist Convection Is Most Vigorous at Intermediate Atmospheric Humidity
The Planetary Science Journal, 2023 In Earth’s current climate, moist convective updraft speeds increase with surface warming. This trend suggests that very vigorous convection might be the norm in extremely hot and humid atmospheres, such as those undergoing a runaway greenhouse ...
