Depths of the eighteen strongest lines in the transit spectra, as well as the metastable helium and calcium infrared triplet lines. The results are shown for the models with a fixed density at the planet radius (right column of Fig. 3). Our computational radial domain extends to 8Rp, corresponding to a maximum absorption of 16.9%, which is reached by various spectral lines. Lines originating from metal atoms (solid) and singly charged ions (dashed) tend to become stronger up to 10x solar metallicity, and then become weaker. Lines originating from doubly or higher charged metal ions (dotted and dash-dotted) keep growing stronger as the metallicity increases. -- astro-ph.EP

The Open-source Sunbather Code: Modeling Escaping Planetary Atmospheres And Their Transit Spectra

by Keith CowingApril 24, 2024April 24, 2024

Atmospheric escape is thought to significantly influence the evolution of exoplanets, especially for sub-Jupiter planets on short orbital periods. Theoretical models predict that hydrodynamic escape could erode the atmospheres of […]
