Linking the evolution of terrestrial interiors and an early outgassed atmosphere to astrophysical observations
@article{Bower2019LinkingTE, title={Linking the evolution of terrestrial interiors and an early outgassed atmosphere to astrophysical observations}, author={Dan J. Bower and Daniel Kitzmann and Aaron S. Wolf and Patrick Sanan and Caroline Dorn and Apurva V. Oza}, journal={Astronomy \& Astrophysics}, year={2019} }
Context. A terrestrial planet is molten during formation and may remain molten due to intense insolation or tidal forces. Observations favour the detection and characterisation of hot planets, potentially with large outgassed atmospheres.
Aims. We aim to determine the radius of hot Earth-like planets with large outgassing atmospheres. Our goal is to explore the differences between molten and solid silicate planets on the mass–radius relationship and transmission and emission spectra.

A coupled numerical framework is presented that links an evolutionary, vertically resolved model of the planetary silicate mantle with a radiative‐convective models of the atmosphere and investigates the early evolution of idealized Earth‐sized rocky planets with end‐member, clear‐sky atmospheres dominated by either H2, H2O, CO2, CH4, CO, O2, or N2.
