TiO and VO broad band absorption features in the optical spectrum of the atmosphere of the hot-Jupiter HD209458b
J. -M. Desert, A. Vidal-Madjar, A. Lecavelier des Etangs +4
The presence of titanium oxide (TiO) and vanadium oxide (VO) gas phase species is searched for in the atmosphere of the hot Jupiter HD209458b. We compared a model for the planets t…
Atmospheric composition and structure of HD209458b
J. -M. Désert, A. Vidal-Madjar, A. Lecavelier des Etangs +4
Transiting planets like HD209458b offer a unique opportunity to scrutinize their atmospheric composition and structure. Transit spectroscopy probes the transition region between th…
Rayleigh scattering by H2 in the extrasolar planet HD209458b
A. Lecavelier des Etangs, A. Vidal-Madjar, J. -M. Desert +1
Transiting planets, such as HD209458b, offer a unique opportunity to scrutinize the planetary atmospheric content. Although molecular hydrogen is expected to be the main atmospheri…
New observations of the extended hydrogen exosphere of the extrasolar planet HD209458b
David Ehrenreich, Alain Lecavelier des Etangs, Guillaume Hébrard +5
Atomic hydrogen escaping from the planet HD209458b provides the largest observational signature ever detected for an extrasolar planet atmosphere. However, the Space Telescope Imag…
Determining atmospheric conditions at the terminator of the hot-Jupiter HD209458b
David K. Sing, A. Vidal-Madjar, A. Lecavelier des Etangs +3
We present a theoretical model fit to the HST/STIS optical transit transmission spectrum of HD209458b. In our fit, we use the sodium absorption line profile along with the Rayleigh…
Exoplanet HD 209458b : Evaporation strengthened
A. Vidal-Madjar, A. Lecavelier des Etangs, J. -M. Desert +4
Following re-analysis of Hubble Space Telescope observations of primary transits of the extrasolar planet HD209458b at Lyman-alpha, Ben-Jaffel (2007, BJ007) claims that no sign of…
