Planetary Albedo Is Limited by the Above-cloud Atmosphere: Implications for Sub-Neptune Climates [PDF]
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 ...

Effects of Transient Stellar Emissions on Planetary Climates of Tidally Locked Exo-Earths [PDF]
Astronomical JournalSpace weather events in exoplanetary environments sourced from transient host star emissions, including stellar flares, coronal mass ejections, and stellar proton events, can substantially influence a planet's habitability and atmospheric evolution ...

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 ...

The Astrophysical Journal, 2023 In this study, we employ a cloud-resolving model to investigate how gravity influences convection and clouds in a small-domain (96 × 96 km) radiative–convective equilibrium.

Superhabitability of High-obliquity and High-eccentricity Planets
The Astrophysical Journal, 2023 Planetary obliquity and eccentricity influence climate by shaping the spatial and temporal patterns of stellar energy incident at a planet’s surface, affecting both the annual mean climate and magnitude of seasonal variability.

Refined Mapping of Subsurface Water Ice on Mars to Support Future Missions
The Planetary Science JournalMars has an extensive yet poorly understood cryosphere. Nevertheless, both direct and indirect evidence indicates extensive buried ice across the midlatitudes, including locations where it is presently unstable.
