Exoplanet atmosphere evolution: emulation with neural networks

We demonstrate there is a relationship between core masses and the atmospheric mass that they retain after disc dispersal, and this trend is consistent with the `boil-off' scenario, in which close-in planets undergo dramatic atmospheric escape during disc dispersal.

Here we present a steady-state model for inner discs accreting viscously, primarily due to the MRI.
