Model atmospheres of irradiated exoplanets: The influence of stellar parameters, metallicity, and the C/O ratio [PDF]
, 2015 Many parameters constraining the spectral appearance of exoplanets are still poorly understood. We therefore study the properties of irradiated exoplanet atmospheres over a wide parameter range including metallicity, C/O ratio and host spectral type.

Observations of Exoplanet Atmospheres [PDF]
, 2015 Detailed characterization of an extrasolar planet's atmosphere provides the best hope for distinguishing the makeup of its outer layers, and the only hope for understanding the interplay between initial composition, chemistry, dynamics & circulation, and

Earth shaped by primordial H_2 atmospheres [PDF]
Nature, 2023 Thermodynamic modelling shows that Earth’s water, core density and overall oxidation state can be explained by the formation of Earth from planetary embryos with hydrogen-rich primary atmospheres and underlying magma oceans.

The Sonora Brown Dwarf Atmosphere and Evolution Models. I. Model Description and Application to Cloudless Atmospheres in Rainout Chemical Equilibrium [PDF]
Astrophysical Journal, 2021 We present a new generation of substellar atmosphere and evolution models, appropriate for application to studies of L-, T-, and Y-type brown dwarfs and self-luminous extrasolar planets.

Atmospheres of Rocky Exoplanets [PDF]
, 2021 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 observing capability, we are poised to characterize the atmospheres of ...

The Surprising Roles of Turbulence in Tropical Cyclone Physics
Atmosphere, 2023 Tropical cyclones have long been known to be powered by turbulent enthalpy fluxes from the ocean’s surface and slowed by turbulent momentum fluxes into the surface.

How Well do We Understand the Planck Feedback?
Journal of Advances in Modeling Earth Systems, 2023 A reference or “no‐feedback” radiative response to warming is fundamental to understanding how much global warming will occur for a given change in greenhouse gases or solar radiation incident on the Earth.

Light absorption by pollution, dust, and biomass burning aerosols: a global model study and evaluation with AERONET measurements [PDF]
Annales Geophysicae, 2009 Atmospheric aerosol distributions from 2000 to 2007 are simulated with the Goddard Chemistry Aerosol Radiation and Transport (GOCART) model to attribute light absorption by aerosol to its composition and sources from pollution, dust, and biomass ...
