Rock vapour is opaque: implications for dynamics and observations of lava planets
T. Giang Nguyen, Nicolas B. Cowan, Gunnar Montseny Gens +3
Extreme instellation on lava planets causes the rocky surface to melt and vaporize. Because the rock vapour composition is intrinsically tied to the mantle, atmospheric characteriz…

The role of interior dynamics and differentiation on the surface and atmosphere of lava planets
Charles-Ãdouard Boukaré, Daphné Lemasquerier, Nicolas Cowan +5
Lava planets are rocky exoplanets that orbit so close to their host star that their day-side is hot enough to melt silicate rock. Their short orbital periods ensure that lava plane…

Thermal Evolution of Lava Planets
Mahesh Herath, Charles-Ãdouard Boukaré, Nicolas B. Cowan
Rocky planets are thought to form with a magma ocean that quickly solidifies. The horizontal and vertical extent of this magma ocean depends on the interior thermal evolution of th…
