NLTE atmospheric modelling of the ultra-hot Jupiter WASP-178b and comparison with UV and optical observations
We model the atmosphere of the ultra-hot Jupiter (UHJ) WASP-178b accounting for NLTE effects and compare synthetic transmission spectra with NUV and optical observations. We use the HELIOS code (LTE) in the lower and the Cloudy code (LTE or NLTE) in the middle and upper atmosphere to compute the temperature-pressure (TP) and abundance profiles. We further use Cloudy to compute the theoretical planetary transmission spectrum both in LTE and NLTE for comparison with observations. We find an isoth…
