Cloud property trends in hot and ultra-hot giant gas planets (WASP-43b, WASP-103b, WASP-121b, HAT-P-7b, and WASP-18b)
Ch. Helling, D. Lewis, D. Samra +8
Ultra-hot Jupiters are the hottest exoplanets discovered so far. Observations begin to provide insight into the composition of their extended atmospheres and their chemical day/nig…
Coexistence of CH4, CO2 and H2O in exoplanet atmospheres
P. Woitke, O. Herbort, Ch. Helling +4
We propose a classification of exoplanet atmospheres based on their H, C, O, N element abundances below about 600 K. Chemical equilibrium models were run for all combinations of H,…
The Atmospheres of Rocky Exoplanets I. Outgassing of Common Rock and the Stability of Liquid Water
Oliver Herbort, Peter Woitke, Christiane Helling +1
Little is known about the interaction between atmospheres and crusts of exoplanets so far, but future space missions and ground-based instruments are expected to detect molecular f…
Understanding the atmospheric properties and chemical composition of the ultra-hot Jupiter HAT-P-7b: I. Cloud and chemistry mapping
Ch. Helling, N. Iro, L. Corrales +10
Ultra-hot Jupiters have recently attracted interest from observers and theoreticians alike, as they provide observationally accessible test cases. We apply a hierarchical modelling…
