The CORALIE survey for southern extra-solar planets. XII. Orbital solutions for 16 extra-solar planets discovered with CORALIE
M. Mayor, S. Udry, D. Naef +4
This paper summarizes the information gathered for 16 still unpublished exoplanet candidates discovered with the CORALIE echelle spectrograph mounted on the Euler Swiss telescope a…
Lithium in stars with exoplanets
Garik Israelian, Nuno Santos, Michel Mayor +1
We present a comparison of the lithium abundances of stars with and without planetary-mass companions. New lithium abundances are reported in 79 planet hosts and 38 stars from a co…
The ELODIE survey for northern extra-solar planets III. Three planetary candidates detected with ELODIE
D. Naef, M. Mayor, J. L. Beuzit +4
We present our ELODIE radial-velocity measurements of HD 74156 and 14 Her (HD 145675). These stars exhibit low-amplitude radial-velocity variations induced by the presence of low-m…
The ELODIE survey for northern extra--solar planets I. 6 new extra--solar planet candidates
C. Perrier, J. P. Sivan, D. Naef +4
Precise radial-velocity observations at Haute-Provence Observatory (OHP, France) with the ELODIE echelle spectrograph have been undertaken since 1994. In addition to several discov…
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…
The CORALIE survey for southern extra-solar planets XI. The return of the giant planet orbiting HD192263
N. C. Santos, S. Udry, M. Mayor +6
The presence of a planet around the K dwarf HD192263 was recently called into question by the detection of a periodic photometric signal with the same period as the one observed in…
