Abstract:
We have performed the detailed analysis of 174 high-resolution spectra
of FGK dwarfs obtained with the ELODIE echelle spectrograph at the
Observatoire de Haute-Provence. Abundances of Fe, Si and Ni have been
determined from equivalent widths under LTE approximation, whereas
abundances of Mg have been determined under NLTE approximation using
equivalent widths of 4 lines and profiles of 5 lines. Spatial
velocities with an accuracy better than 1kms, as well as orbits,
have been computed for all stars.
