We model the formation of silicate atmospheres on hot volatile-free super-Earths. Our calculations assume that all volatile elements such as H, C, N, S, and Cl have been lost from the planet. We find that the atmospheres are composed primarily of Na, O2, O, and SiO gas, in order of decreasing abundance. The atmospheric composition may be altered by fractional vaporization, cloud condensation, photoionization, and reaction with any residual volatile elements remaining in the atmosphere.

Vaporization of the Earth: Application to Exoplanet Atmospheres
Currently, there are about three dozen known super-Earths (M < 10 M ⊕), of which eight are transiting planets suitable for atmospheric follow-up observations. Some of the planets are exposed toExpand
Atmospheres of Hot Super-Earths
Hot super-Earths likely possess minimal atmospheres established through vapor saturation equilibrium with the ground. We solve the hydrodynamics of these tenuous atmospheres at the surface ofExpand

Hot Super-Earth Atmospheres
The search for extrasolar planets has resulted in the discovery of super-Earths, with masses less than ten Earth masses. Regarding the orbital distances, some of these planets are very close to itsExpand
