MELTYQ Archives

Schematics of the MELTYQ coupled magma-atmosphere retrieval. The model is valid for sub-Neptune hosting a thick H2-rich atmosphere with enough surface temperature to melt rocks. The model splits the planet in three regions: a rocky core, a deep atmosphere, and an upper atmosphere. The chemistry is coupled allowing to retrieve the composition of the rocky magma via it’s influence on the observable atmosphere. -- astro-ph.EP
