Magnesium in the atmosphere of the planet HD209458b: Observations of the thermosphere-exosphere transition region
A. Vidal-Madjar, C. M. Huitson, V. Bourrier +8
We report new near ultraviolet HST/STIS observations of atmospheric absorptions during the planetary transit of HD209458b. We detect absorption in atomic magnesium (MgI), while no…
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…
Detection of oxygen and carbon in the hydrodynamically escaping atmosphere of the extrasolar planet HD209458b
A. Vidal-Madjar, J. -M. Désert, A. Lecavelier des Etangs +7
Four transits of the planet orbiting the star HD209458 were observed with the STIS spectrograph on board HST. The wavelength domain (1180-1710A) includes HI as well as CI, CII, CIV…
