Detection of an atmosphere around the super-Earth 55 Cancri e
A. Tsiaras, M. Rocchetto, I. P. Waldmann +8
We report the analysis of two new spectroscopic observations of the super-Earth 55 Cancri e, in the near infrared, obtained with the WFC3 camera onboard the HST. 55 Cancri e orbits…
Fingering convection and cloudless models for cool brown dwarf atmospheres
P. Tremblin, D. S. Amundsen, P. Mourier +5
This work aims to improve the current understanding of the atmospheres of brown dwarfs, especially cold ones with spectral type T and Y, whose modeling is a current challenge. Sili…
VUV-absorption cross section of CO2 at high temperatures and impact on exoplanet atmospheres
Olivia Venot, Nicolas Fray, Yves Bénilan +6
Ultraviolet (UV) absorption cross sections are an essential ingredient of photochemical atmosphere models. Exoplanet searches have unveiled a large population of short-period objec…
The EChO science case
Giovanna Tinetti, Pierre Drossart, Paul Eccleston +347
The discovery of almost 2000 exoplanets has revealed an unexpectedly diverse planet population. Observations to date have shown that our Solar System is certainly not representativ…
New chemical scheme for studying carbon-rich exoplanet atmospheres
Olivia Venot, Eric Hébrard, Marcelino Agúndez +2
Atmospheres with a high C/O ratio are expected to contain an important quantity of hydrocarbons, including heavy molecules (with more than 2 carbon atoms). To study correctly these…
