Fe I in the Beta Pictoris circumstellar gas disk. II. The time variations in the iron circumstellar gas
Flavien Kiefer, Alfred Vidal-Madjar, Alain Lecavelier des Etangs +5
Beta Pictoris is a young planetary system surrounded by a debris disk of dust and gas. The gas source of this disk could be exocomets (or 'falling and evaporating bodies', FEBs), w…
The long egress of GJ~436b's giant exosphere
B. Lavie, D. Ehrenreich, V. Bourrier +8
The M dwarf GJ 436 hosts a transiting warm Neptune known to experience atmospheric escape. Previous observations revealed the presence of a giant hydrogen exosphere transiting the…
Molecular Hydrogen in the FUSE Translucent Lines of Sight: The Full Sample
Brian L. Rachford, Theodore P. Snow, Joshua D. Destree +13
We report total abundances and related parameters for the full sample of the FUSE survey of molecular hydrogen in 38 translucent lines of sight. New results are presented for the "…
EROS 2 photometry of probable R Coronae Borealis stars in the Small Magellanic Cloud
P. Tisserand, J. B. Marquette, J. P. Beaulieu +1
EROS 2 (Experience de Recherche d'Objets Sombres) conducted a survey of the SMC between July 1996 and February 2003 in two EROS broad-band colours, V_E and R_E. The photometric dat…
The data analysis of HD209458 Ly-alpha transit occultation
J. -M. Désert, A. Vidal-Madjar, A. Lecavelier des Étangs +4
Using STIS - HST observations, we have detected an extended upper atmosphere in the extrasolar planet HD209458b . The spectra show an absorption of (15+/-4)% of the stellar Ly-alph…
"Osiris"(HD209458b), an evaporating planet
Alfred Vidal-Madjar, Alain Lecavelier des Etangs
Three transits of the planet orbiting the solar type star HD209458 were observed in the far UV at the wavelength of the HI Ly-alpha line. The planet size at this wavelength is equa…
