Journal ArticleDOI
Radius and mass of a transiting M dwarf near the hydrogen-burning limit. OGLE-TR-123
Frederic Pont,C. Moutou,François Bouchy,Raoul Behrend,Michel Mayor,Stéphane Udry,Didier Queloz,Nuno C. Santos,Claudio Melo +8 more
TL;DR: The OGLE-TR-123b system was shown by subsequent spectroscopic follow-up to be an eclipsing binary with a very low mass companion (M 2 ∼ 0.085 ± 0.011 M ○) as mentioned in this paper.
Proceedings ArticleDOI

TL;DR: The High Accuracy Radial velocity Planet Searcher (HARPS) as mentioned in this paper is a high-resolution spectrograph dedicated to the extremely precise measurement of stellar radial velocities.
Journal ArticleDOI
Solar-like Oscillations in the Metal-poor Subgiant ν Indi: Constraining the Mass and Age Using Asteroseismology
Timothy R. Bedding,R. Paul Butler,Fabien Carrier,François Bouchy,Brendon J. Brewer,Patrick Eggenberger,Frank Grundahl,Hans Kjeldsen,Chris McCarthy,Tine Nielsen,A. Retter,A. Retter,C. G. Tinney +12 more
TL;DR: Asteroseismology is a powerful method for determining fundamental properties of stars as mentioned in this paper, and the first application to a metal-poor object, namely the subgiant star ν Ind, was reported.
Proceedings ArticleDOI
The exoplanet hunter HARPS: unequalled accuracy and perspectives toward 1 cm s-1 precision
Christophe Lovis,Francesco Pepe,François Bouchy,Gaspare Lo Curto,Michel Mayor,Luca Pasquini,Didier Queloz,Gero Rupprecht,Stéphane Udry,Shay Zucker +9 more
TL;DR: The HARPS spectrograph as discussed by the authors achieved the highest radial velocity precision ever, thanks to high mechanical and environmental stability, stable illumination, accurate wavelength calibration and tracking of instrumental drifts.
Journal ArticleDOI
