Frame Combination Techniques for Ultra High-Contrast Imaging
Joseph C. Carson, Markus Feldt, Silvano Desidera +4
We summarize here an experimental frame combination pipeline we developed for ultra high-contrast imaging with systems like the upcoming VLT SPHERE instrument. The pipeline combine…
Pupil stabilization for SPHERE's extreme AO and high performance coronagraph system
G. Montagnier, T. Fusco, J. -L. Beuzit +3
We propose a new concept of pupil motion sensor for astronomical adaptive optics systems and present experimental results obtained during the first laboratory validation of this co…
The ELODIE survey for northern extra-solar planets IV. HD196885, a close binary star with a 3.7-year planet
A. C. M. Correia, S. Udry, M. Mayor +9
Aims:We aim to significantly increase the number of detected extra-solar planets in a magnitude-limited sample to improve our knowledge of their orbital element distributions and t…
Elodie metallicity-biased search for transiting Hot Jupiters IV. Intermediate period planets orbiting the stars HD43691 and HD132406
R. Da Silva, S. Udry, F. Bouchy +21
We report here the discovery of two planet candidates as a result of our planet-search programme biased in favour of high-metallicity stars, using the ELODIE spectrograph at the Ob…
Refined parameters and spectroscopic transit of the super-massive planet HD147506b
B. Loeillet, A. Shporer, F. Bouchy +26
In this paper, we report a refined determination of the orbital parameters and the detection of the Rossiter-McLaughlin effect of the recently discovered transiting exoplanet HD147…
Extrasolar planets and brown dwarfs around A-F type stars. IV. A candidate brown dwarf around the A9V pulsating star HD180777
F. Galland, A. M. Lagrange, S. Udry +3
We present here the detection of a brown dwarf orbiting the A9V star HD180777. The radial velocity measurements, obtained with the ELODIE echelle spectrograph at the Haute-Provence…
