[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…
Fundamental properties of the open cluster NGC 2355
C. Soubiran, M. Odenkirchen, J. -F. Le Campion
NGC 2355 is an old open cluster in the outer part of the galactic disk (l=203 deg, b=+11 deg) which has been little studied until now. This paper presents the first astrometric and…
On-line determination of stellar atmospheric parameters Teff, log g, [Fe/H] from ELODIE echelle spectra. I - The method
D. Katz, C. Soubiran, R. Cayrel +2
We present a method estimating the atmospheric parameters Teff, log g, [Fe/H] for stars observed, even at low signal to noise ratio, with the echelle spectrograph ELODIE on the 193…
