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…
The GAPS programme at TNG. XLV. HI Balmer lines transmission spectroscopy and NLTE atmospheric modelling of the ultra-hot Jupiter KELT-20b/MASCARA-2b
L. Fossati, F. Biassoni, G. M. Cappello +27
We aim at extracting the transmission spectrum of the HI Balmer lines of the ultra-hot Jupiter (UHJ) KELT-20b/MASCARA-2b from observations and to further compare the results with w…
Mass loss by atmospheric escape from extremely close-in planets
Tommi Koskinen, Panayotis Lavvas, Chenliang Huang +3
We explore atmospheric escape from close-in exoplanets with the highest mass loss rates. First, we locate the transition from stellar X-ray and UV-driven escape to rapid Roche lobe…
Black Mirror: The impact of rotational broadening on the search for reflected light from 51 Pegasi b with high resolution spectroscopy
E. F. Spring, J. L. Birkby, L. Pino +6
The extreme contrast ratios between stars and their planets at optical wavelengths make it challenging to isolate the light reflected by exoplanet atmospheres. Yet, these reflectiv…
High-resolution detection of neutral oxygen and non-LTE effects in the atmosphere of KELT-9b
Francesco Borsa, Luca Fossati, Tommi Koskinen +2
Oxygen is a constituent of many of the most abundant molecules detected in exoplanetary atmospheres and a key ingredient for tracking how and where a planet formed. In particular,…
Non-local thermodynamic equilibrium effects determine the upper atmospheric temperature structure of the ultra-hot Jupiter KELT-9b
L. Fossati, M. E. Young, D. Shulyak +5
Several results indicate that the atmospheric temperature of the ultra-hot Jupiter KELT-9b in the main line formation region is a few thousand degrees higher than predicted by self…
