A new chemical scheme for giant planet thermochemistry. Update of the methanol chemistry and new reduced chemical scheme
Olivia Venot, Thibault Cavalié, Roda Bounaceur +3
Several chemical networks have been developed to study warm (exo)planetary atmospheres. The kinetics of the reactions related to the methanol chemistry included in these schemes ha…
Idealised simulations of the deep atmosphere of hot jupiters: Deep, hot, adiabats as a robust solution to the radius inflation problem
F. Sainsbury-Martinez, P. Wang, S. Fromang +10
Context: The anomalously large radii of hot Jupiters has long been a mystery. However, by combining both theoretical arguments and 2D models, a recent study has suggested that the…
An independent analysis of the Spitzer/IRAC phase curves of WASP43 b
Giuseppe Morello, Camilla Danielski, Daniel Dicken +2
We present here a reanalysis of the Spitzer Space Telescope phase curves of the hot Jupiter WASP43 b, using the wavelet pixel-Independent Component Analysis, a blind signal-source…
An emission spectrum for WASP-121b measured across the 0.8-1.1 micron wavelength range using the Hubble Space Telescope
Thomas Mikal-Evans, David K. Sing, Jayesh M. Goyal +11
WASP-121b is a transiting gas giant exoplanet orbiting close to its Roche limit, with an inflated radius nearly double that of Jupiter and a dayside temperature comparable to a lat…
A reduced chemical scheme for modelling warm to hot hydrogen-dominated atmospheres
Olivia Venot, Roda Bounaceur, Michel Dobrijevic +5
Three dimensional models that account for chemistry are useful tools to predict the chemical composition of (exo)planet and brown dwarf atmospheres and interpret observations of fu…
Thermo-compositional diabatic convection in the atmospheres of brown dwarfs and in Earth's atmosphere and oceans
P. Tremblin, T. Padioleau, M. Phillips +12
By generalizing the theory of convection to any type of thermal and compositional source terms (diabatic processes), we show that thermohaline convection in Earth oceans, fingering…
