Toward the analysis of JWST exoplanet spectra: Identifying troublesome model parameters

Jean-Loup Baudino, Paul Molliere, Olivia Venot +3

Given the forthcoming launch of the James Webb Space Telescope (JWST) which will allow observ- ing exoplanet atmospheres with unprecedented signal-over-noise ratio, spectral covera…

VUV-absorption cross section of carbon dioxide from 150 to 800 K and applications to warm exoplanetary atmospheres

Olivia Venot, Yves Bénilan, Nicolas Fray +9

Most exoplanets detected so far have atmospheric T significantly higher than 300K. Often close to their star, they receive an intense UV photons flux that triggers important photod…

MASCARA-1 b: A hot Jupiter transiting a bright A-star in a misaligned orbit

G. J. J. Talens, S. Albrecht, J. F. P. Spronck +11

We report the discovery of MASCARA-1 b, the first exoplanet discovered with the Multi-site All-Sky CAmeRA (MASCARA). It is a hot Jupiter orbiting a bright , rapidly rotati…

Thermochemistry and vertical mixing in the tropospheres of Uranus and Neptune: How convection inhibition can affect the derivation of deep oxygen abundances

Thibault Cavalié, Olivia Venot, Franck Selsis +3

Thermochemical models have been used in the past to constrain the deep oxygen abundance in the gas and ice giant planets from tropospheric CO spectroscopic measurements. Knowing th…
