Aerosol Composition of Hot Giant Exoplanets Dominated by Silicates and Hydrocarbon Hazes
Peter Gao, Daniel P. Thorngren, Elspeth K. H. Lee +6
Aerosols are common in the atmospheres of exoplanets across a wide swath of temperatures, masses, and ages. These aerosols strongly impact observations of transmitted, reflected, a…
The effect of internal gravity waves on cloud evolution in sub-stellar atmospheres
Amy Parent, Ruth E. Falconer, Elspeth K. H. Lee +2
Sub-stellar objects exhibit photometric variability, which is believed to be caused by a number of processes, such as magnetically-driven spots or inhomogeneous cloud coverage. Rec…
Simulating the cloudy atmospheres of HD 209458 b and HD 189733 b with the 3D Met Office Unified Model
S. Lines, N. J. Mayne, Ian A. Boutle +9
To understand and compare the 3D atmospheric structure of HD 209458 b and HD 189733 b, focusing on the formation and distribution of cloud particles, as well as their feedback on t…
Dynamic mineral clouds on HD 189733b II. Monte Carlo radiative transfer for 3D cloudy exoplanet atmospheres: combining scattering and emission spectra
Elspeth Lee, Kenneth Wood, Ian Dobbs-Dixon +2
As the 3D spatial properties of exoplanet atmospheres are being observed in increasing detail by current and new generations of telescopes, the modelling of the 3D scattering effec…
Dust in brown dwarfs and extra-solar planets V. Cloud formation in carbon- and oxygen-rich environment
Ch. Helling, D. Tootill, P. Woitke +1
Recent observations indicate potentially carbon-rich exoplanet atmospheres. Spectral fitting methods for brown dwarfs and exoplanets have invoked the C/O ratio as additional parame…
The mineral clouds on HD 209458b and HD189733b
Ch. Helling, G. Lee, I. Dobbs-Dixon +7
3D atmosphere model results are used to comparatively study the kinetic, non-equilibrium cloud formation in the atmospheres of two example planets guided by the giant gas planets H…
