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…
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…
Rayleigh scattering in the transit spectrum of HD 189733b
A. Lecavelier des Etangs, F. Pont, A. Vidal-Madjar +1
The transit spectrum of the exoplanet HD 189733b has recently been obtained between 0.55 and 1.05 microns. Here we present an analysis of this spectrum. We develop first-order equa…
HST/STIS Optical Transit Transmission Spectra of the hot-Jupiter HD209458b
David K. Sing, A. Vidal-Madjar, J. -M. Desert +2
We present the transmission spectra of the hot-Jupiter HD209458b taken with the Space Telescope Imaging Spectrograph aboard the Hubble Space Telescope. Our analysis combines data a…
