[alpha/Fe] in the thin and the thick disk towards an automatic parametrization of stellar spectra
Pascal Girard, Caroline Soubiran
We test an automatic procedure to measure [Fe/H] and [alpha/Fe] on high resolution spectra. The test sample is the intersection of the ELODIE library and a catalogue of 830 stars h…
Abundances and ages of the deconvolved thin/thick disks of the Galaxy
Pascal Girard, Caroline Soubiran
We have investigated the abundance of several chemical elements in two large stellar samples kinematically representative of the thin and the thick disks of the Galaxy. Chemical, k…
A new Bohm-Vitense gap in the temperature range 5560 to 5610K in the Main Sequence
V. V. Kovtyukh, C. Soubiran, S. I. Belik
Highly precise temperatures (sigma = 10-15 K) have been determined from line depth ratios for a set of 248 F-K field dwarfs of about solar metallicity (-0.5 < [Fe/H] < +0.4), based…
GAUDI: a preparatory archive for the COROT mission
E. Solano, C. Catala, R. Garrido +34
The GAUDI database (Ground-based Asteroseismology Uniform Database Interface, http://sdc.laeff.esa.es/gaudi/) is a preparatory archive for the COROT (COnvection, ROtation and plane…
Spectroscopic survey of the Galaxy with Gaia I. Design and performance of the Radial Velocity Spectrometer
D. Katz, U. Munari, M. Cropper +22
The definition and optimisation studies for the Gaia satellite spectrograph, the Radial Velocity Spectrometer (RVS), converged in late 2002 with the adoption of the instrument base…
Evolutionary synthesis of galaxies at high spectral resolution with the code PEGASE-HR
Damien Le Borgne, Brigitte Rocca-Volmerange, Philippe Prugniel +3
We present PEGASE-HR, a new stellar population synthesis program generating high resolution spectra (R=10 000) over the optical range lambda=400--680 nm. It links the spectro-photo…
The ELODIE archive
J. Moultaka, S. A. Ilovaisky, Ph. Prugniel +1
The ELODIE archive contains the complete collection of high-resolution echelle spectra accumulated over the last decade using the ELODIE spectrograph at the Observatoire de Haute-P…
On the correlation of elemental abundances with kinematics among galactic disk stars
T. V. Mishenina, C. Soubiran, V. V. Kovtyukh +1
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…
