Three-dimensional transport-induced chemistry on temperate sub-Neptune K2-18b, Part II: the combined effects of atmospheric dynamics and chemical reactions
Jiachen Liu, Duncan Christie, Jun Yang +1
The upper atmospheres of temperate sub-Neptunes are strongly influenced by atmospheric dynamics due to their cool equilibrium temperature and thereby longer chemical timescales tha…
The Impact of Different Haze Types on the Atmosphere and Observations of Hot Jupiters: 3D Simulations of HD 189733b, HD209458b and WASP-39b
Mei Ting Mak, Denis Sergeev, Nathan Mayne +6
We present the results from the simulations of the atmospheres of hot-Jupiters HD189733b, HD209458b and WASP-39b, assuming the presence of three different types of haze. Using a 3D…
Geometric Considerations in Hot Jupiter Magnetic Drag Models
Duncan A. Christie, Tom M. Evans-Soma, Nathan J. Mayne +1
Magnetic fields are expected to impact the atmospheric dynamics of hot and ultra-hot Jupiters due to their increased ionization fractions, compared to that of cooler exoplanets, bu…
3D simulations of TRAPPIST-1e with varying CO2, CH4 and haze profiles
Mei Ting Mak, Denis Sergeev, Nathan Mayne +6
Using a 3D General Circulation Model, the Unified Model, we present results from simulations of a tidally-locked TRAPPIST-1e with varying carbon dioxide CO2 and methane CH4 gas con…
Quenching-driven equatorial depletion and limb asymmetries in hot Jupiter atmospheres: WASP-96b example
Maria Zamyatina, Duncan A. Christie, Eric Hébrard +11
Transport-induced quenching in hot Jupiter atmospheres is a process that determines the boundary between the part of the atmosphere at chemical equilibrium and the part of the atmo…
The impact of the explicit representation of convection on the climate of a tidally locked planet in global stretched-mesh simulations
Denis E. Sergeev, Ian A. Boutle, F. Hugo Lambert +5
Convective processes are crucial in shaping exoplanetary atmospheres but are computationally expensive to simulate directly. A novel technique of simulating moist convection on tid…
