Abundance ratios of volatile vs. refractory elements: hints of pollutions?
A. Ecuvillon, G. Israelian, N. C. Santos +2
We present the abundance ratios [X/H] of a large set of chemical species with condensation temperatures from 75 to 1600 K in an almost complete set of 105 planet-host stars and in…
Metallicity of M dwarfs I. A photometric calibration and impact on the mass-luminosity relation at the bottom of the main sequence
X. Bonfils, X. Delfosse, S. Udry +3
We obtained high resolution ELODIE and CORALIE spectra for both components of 20 wide visual binaries composed of an F-, G- or K-dwarf primary and an M-dwarf secondary. We analyse…
Confirming the Metal-Rich Nature of Stars with Giant Planets
Nuno C. Santos, Garik Israelian, Michel Mayor
With the goal of confirming the metallicity ``excess'' observed in stars with planetary mass companions, we have conducted a high-precision spectroscopic study of a ``comparison''…
Bisector analysis as a diagnostic of intrinsic radial-velocity variations
N. C. Santos, M. Mayor, D. Naef +2
In this contribution we present the results of the application of the bisector of the cross-correlation function as a diagnostic of activity-related radial-velocity variations. The…
A planet orbiting the star Gliese 86
D. Queloz, M. Mayor, L. Weber +7
A 4MJ planet with a 15.8day orbital period has been detected from very precise radial velocity measurements with the CORALIE echelle spectrograph. A second remote and more massive…
