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…
Thermal Evolution of Lava Planets
Mahesh Herath, Charles-Édouard 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…
The role of interior dynamics and differentiation on the surface and atmosphere of lava planets
Charles-Édouard 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…
The Role of Magma Oceans in Maintaining Surface Water on Rocky Planets Orbiting M-Dwarfs
Keavin Moore, Nicolas B. Cowan, Charles-Édouard Boukaré
Earth-like planets orbiting M-dwarf stars, M-Earths, are currently the best targets to search for signatures of life. Life as we know it requires water. The habitability of M-Earth…
