Helium escaping from the atmosphere of a nearby rocky exoplanet orbiting in a habitable zone
Collin Cherubim, Shreyas Vissapragada, Tim Cunningham +13
Observations of highly irradiated gas giant exoplanets have shown helium escaping from their atmospheres. There is limited evidence for atmospheres on rocky exoplanets, perhaps bec…
Climates of temperate rocky planets with He-dominated atmospheres
Viviane Kuss, Robin Wordsworth, Collin Cherubim +1
We present radiative-convective modeling of rocky exoplanets with -dominated atmospheres and low envelope mass fractions. Helium has a steeper adiabatic temperature profile tha…
Analytic Modeling of Tidally Locked Rocky Planet Atmospheres Across Dynamical Regimes
Christopher P. Wirth, Diana Powell, Robin Wordsworth
We present a new first-principles analytic approach to interpreting eclipses and phase curves of rocky planets. Observations with JWST have reported nondetections of atmospheres ar…
Characterizing the Radiative-Convective Structure of Dense Rocky Planet Atmospheres
Jessica Cmiel, Robin Wordsworth, Jacob T. Seeley
We use a one-dimensional line-by-line radiative-convective model to simulate hot, dense terrestrial-planet atmospheres. We find that strong shortwave absorption by H2O and CO2 inhi…
Resolved convection in hydrogen-rich atmospheres
Jacob T. Seeley, Robin D. Wordsworth
In hydrogen-rich atmospheres with low mean molecular weight (MMW), an air parcel containing a higher-molecular-weight condensible can be negatively buoyant even if its temperature…
Fermi Resonance and the Quantum Mechanical Basis of Global Warming
Robin Wordsworth, Jacob Seeley, Keith Shine
Although the scientific principles of anthropogenic climate change are well-established, existing calculations of the warming effect of carbon dioxide rely on spectral absorption d…
Atmospheres of Rocky Exoplanets
R. Wordsworth, L. Kreidberg
Rocky planets are common around other stars, but their atmospheric properties remain largely unconstrained. Thanks to a wealth of recent planet discoveries and upcoming advances in…
Transient conditions for biogenesis on low-mass exoplanets with escaping hydrogen atmospheres
R. Wordsworth
Exoplanets with lower equilibrium temperatures than Earth and primordial hydrogen atmospheres that evaporate after formation should pass through transient periods where oceans can…
