Figure 4:
Comparison of the abundances of Na, Ni and elements for the
five clusters in the present paper (red filled circles) and i) thin-disk field
stars (grey open squares, Soubiran & Girard 2005); ii) NGC 6253 (blue filled
circle, S07); iii) NGC 6819, Cr 261 and NGC 6791 (green filled squares,
Bragaglia et al. 2001; Carretta et al. 2005, 2007); iv) the
outer Galactic disk clusters Be 31, Be 29, Be 20, NGC 2141, plus M 67 (orange
filled triangles, Yong et al. 2005); the outer Galactic disk clusters Be 22,
Be 66 and Saurer 1 (purple inverse triangles, Villanova et al. 2005; Carraro et al. 2004). The comparison of Ba abundances for the same OCs is made with Allende Prieto et al. (2004, grey crosses). |
