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…
Fe I in the β Pictoris circumstellar gas disk I. Physical properties of the neutral iron gas
A. Vidal-Madjar, F. Kiefer, A. Lecavelier des Etangs +5
The young planetary system β Pictoris is surrounded by a circumstellar disk of dust and gas. Because both dust and gas have a lifetime shorter than the system age, they need to be…
First Detection of Hydrogen in the β Pictoris Gas Disk
P. A. Wilson, A. Lecavelier des Etangs, A. Vidal-Madjar +6
The young and nearby star β Pictoris (β Pic) is surrounded by a debris disk composed of dust and gas known to host a myriad evaporating exocomets, planetesimals and at least one pl…
The Earth as an extrasolar transiting planet - II: HARPS and UVES detection of water vapor, biogenic O, and O
Luc Arnold, David Ehrenreich, Alfred Vidal-Madjar +9
The atmospheric composition of transiting exoplanets can be characterized during transit by spectroscopy. For the transit of an Earth twin, models predict that biogenic and $…
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…
Building galaxies, stars, planets and the ingredients for life between the stars. A scientific proposal for a European Ultraviolet-Visible Observatory (EUVO)
Ana I. Gómez de Castro, Thierry Appourchaux, Martin Barstow +36
The growth of luminous structures and the building blocks of life in the Universe began as primordial gas was processed in stars and mixed at galactic scales. The mechanisms respon…
