Five new very low mass binaries
G. Montagnier, D. Segransan, J. -L. Beuzit +12
We report the discovery of companions to 5 nearby late M dwarfs (>M5), LHS1901, LHS4009, LHS6167, LP869-26 and WT460, and we confirm that the recently discovered mid-T brown dwarf…
ELODIE metallicity-biased search for transiting Hot Jupiters V. An intermediate-period Jovian planet orbiting HD45652
N. C. Santos, S. Udry, F. Bouchy +20
We present the detection of a 0.47 Jupiter mass planet in a 44-day period eccentric trajectory (e=0.39) orbiting the metal-rich star HD45652. This planet, the seventh giant planet…
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…
The SOPHIE search for northern extrasolar planets. V. Follow-up of ELODIE candidates: Jupiter-analogs around Sun-like stars
I. Boisse, F. Pepe, C. Perrier +21
We present radial-velocity measurements obtained in a programs underway to search for extrasolar planets with the spectrograph SOPHIE at the 1.93-m telescope of the Haute-Provence…
The HARPS search for southern extra-solar planets XXXI. The M-dwarf sample
X. Bonfils, X. Delfosse, S. Udry +11
(Abridged) Searching for planets around stars with different masses probes the outcome of planetary formation for different initial conditions. This drives observations of a sample…
The ELODIE survey for northern extra-solar planets II. A Jovian planet on a long-period orbit around GJ 777 A
D. Naef, M. Mayor, S. G. Korzennik +8
We present radial-velocity measurements obtained with the ELODIE and AFOE spectrographs for GJ 777 A (HD 190360), a metal-rich ([Fe/H]=0.25) nearby (d=15.9 pc) star in a stellar bi…
