Oxygen in old and thick disk stars.

B. Barbuy, M. Erdelyi-Mendes

Abstract

Les spectres Reticon et CCD comprenant la raie |OI| λ6300.311 ont ete obtenus pour les etoiles du disque vieux et epais. Les vitesses spatiales sont etudiees afin de classifier les etoiles dans les differents groupes de population. Les parametres atmospheriques sont utilises pour determiner l'abondance d'oxygene avec les calculs des spectres synthetiques
