Transmission spectrum of Venus as a transiting exoplanet
David Ehrenreich, Alfred Vidal-Madjar, Thomas Widemann +6
On 5-6 June 2012, Venus will be transiting the Sun for the last time before 2117. This event is an unique opportunity to assess the feasibility of the atmospheric characterisation…
Corrigendum to "The upper atmosphere of the exoplanet HD209458b revealed by the sodium D lines: Temperature-pressure profile, ionization layer and thermosphere" [2011, A&A, 527, A110]
A. Vidal-Madjar, C. M. Huitson, A. Lecavelier des Etangs +7
An error was detected in the code used for the analysis of the HD209458b sodium profile (Vidal-Madjar et al. 2011). Here we present an updated T-P profile and briefly discuss the c…
GMRT search for 150 MHz radio emission from the transiting extrasolar planets HD189733b and HD209458b
A. Lecavelier des Etangs, S. K. Sirothia, Gopal-Krishna +1
We report a sensitive search for meter-wavelength emission at 150 MHz from two prominent transiting extrasolar planets, HD189733b and HD209458b. To distinguish any planetary emissi…
Hubble Space Telescope Transmission Spectroscopy of the Exoplanet HD 189733b: High-altitude atmospheric haze in the optical and near-UV with STIS
D. K. Sing, F. Pont, S. Aigrain +10
We present Hubble Space Telescope optical and near-ultraviolet transmission spectra of the transiting hot-Jupiter HD189733b, taken with the repaired Space Telescope Imaging Spectro…
HST/STIS Lyman-alpha observations of the quiet M dwarf GJ436: Predictions for the exospheric transit signature of the hot neptune GJ436b
David Ehrenreich, Alain Lecavelier des Etangs, Xavier Delfosse
Lyman-alpha (Lya) emission of neutral hydrogen (1215.67 Angström) is the main contributor to the ultraviolet flux of low-mass stars such as M dwarfs. It is also the main light sour…
