H2 Chemistry and Protonation in the Dayside Venusian Upper Atmosphere

open access: yesThe Astronomical Journal
Although H _2 is present in low concentrations, it critically controls the structure and composition of planetary upper atmospheres through protonation under solar extreme-ultraviolet and soft X-ray irradiation. Recent studies highlight the importance of

Strong Fractionation of Deuterium and Helium in Sub-Neptune Atmospheres along the Radius Valley

open access: yesThe Astrophysical Journal
We simulate atmospheric fractionation in escaping planetary atmospheres using IsoFATE , a new open-source numerical model. We expand the parameter space studied previously to planets with tenuous atmospheres that exhibit the greatest helium and deuterium

The dynamics of planetary atmospheres

open access: yes, 2016
Current knowledge of the dynamics of the atmospheres of the planets is reviewed. This has expanded a great deal in recent years, due to the numerous space missions which have gathered new observational data. Nevertheless, there is also much which remains unknown, and many cases where new observations have simply posed additional questions of a ...

Simultaneous Evolutionary Fits for Jupiter and Saturn Incorporating Fuzzy Cores

open access: yesThe Astrophysical Journal Letters
With the recent realization that there likely are stably stratified regions in the interiors of both Jupiter and Saturn, we construct new nonadiabatic, inhomogeneous evolutionary models with the same microphysics for each that result at the present time ...
