HARPS, a new high-resolution spectrograph for the search of extra-solar planets (2007)

Francesco Pepe, Michel Mayor, Bernard Delabre, Dominique Kohler, Daniel Lacroix, Didier Queloz, ...

HARPS (High-Accuracy Radial-velocity Planetary Search) is a high-resolution spectrograph dedicated to the search for extra-solar planets by means of precise radial-velocity (RV) measurements. It will...

Extrasolar Planetary Systems or Spectroscopic Binaries? Discrimination using Spectral Line Properties (2007)

Dominique Naef Michel, Michel Mayor, Jean-luc Beuzit, Didier Queloz, Jean-pierre Sivan

. We confirm the orbital solutions for the planetary companions orbiting the solar-type stars 47 UMa and 70 Vir using radial velocity data obtained with the ELODIE echelle spectrograph. Using our...

Extended Red Emission (ERE) detected in the 30 Doradus nebula (1998)

Darbon, Stephane, Perrin, Jean-Marie, Sivan, Jean-Pierre

We present low-dispersion visible spectra of two regions of the 30 Doradus nebula. When corrected for atomic continuum emission and divided by the spectrum of the exciting and illuminating stars, one...
