The Solubility of N2 in High-pressure Ice and Its Consequent Outgassing Limitations in Water Worlds

The Astrophysical Journal
Exoplanets with a few percent water mass fraction may host a high-pressure ice layer that separates the atmosphere from the interior. We investigate the role played by this layer in the transport of N _2 between the interior and the atmosphere.

Next-generation Improvements in Giant-exoplanet Evolutionary and Structural Models

The Astrophysical Journal
Many evolutionary models of giant exoplanets still rely on simplifying assumptions that are no longer adequate, given detailed constraints from Jupiter, Saturn, and modern exoplanet observations.

Thermal structure, composition, atmospheric dynamics and long-terme evolution of irradiated exoplanets

, 2014
More than a thousand exoplanets have been discovered over the last decade. Perhaps more excitingly, probing their atmospheres has become possible. We now have spectra of hot Jupiters like HD 189733b and HD 209458b, of Neptune-like planets like GJ1214b and even smaller planets are within reach.

The First Dedicated Survey of Atmospheric Escape from Planets Orbiting F Stars

The Astronomical Journal
Hydrodynamic escape can strip the envelopes of close-in exoplanets, but most observations of atmospheric mass loss to date have been confined to planets orbiting K and M dwarfs.

Reduced Water Loss due to Photochemistry on Terrestrial Planets in the Runaway Greenhouse Phase around Pre-main-sequence M Dwarfs

The Astrophysical Journal
Terrestrial planets currently in the habitable zone around M dwarfs are estimated to have been in runaway greenhouse conditions for up to ∼1 Gyr due to the long-term pre-main-sequence phase of M dwarfs.
