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…
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…
A Spitzer Search for Water in the Transiting Exoplanet HD189733b
David Ehrenreich, Guillaume Hébrard, Alain Lecavelier Des Etangs +5
We present Spitzer Space Telescope observations of the extrasolar planet HD189733b primary transit, obtained simultaneously at 3.6 and 5.8 microns with the Infrared Array Camera. T…
Abundance differences between the neutral and the ionized gas of the dwarf galaxy IZw 36
V. Lebouteiller, D. Kunth, J. Lequeux +4
We present a FUSE spectroscopic study of the nearby gas--rich, metal--deficient blue compact dwarf (BCD) galaxy IZw 36. Atomic hydrogen and many metal lines are observed in absorpt…
