Magnetohydrodynamic simulation assessment of a potential near-ultraviolet early ingress in WASP-189b

Y. Duann, S. -H. Lai, H. J. Hoeijmakers +8

Ultra-hot Jupiters (UHJs) in close orbits around early-type stars provide natural laboratories for studying atmospheric escape and star-planet interactions under extreme irradiatio…

NLTE atmospheric modelling of the ultra-hot Jupiter WASP-178b and comparison with UV and optical observations

L. Fossati, A. G. Sreejith, T. Koskinen +6

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 th…
