Chemical Homogeneity in Collinder 261 and Implications for Chemical Tagging

G. M. De Silva, K. C. Freeman, M. Asplund +3

This paper presents abundances for 12 red giants of the old open cluster Collinder 261 based on spectra from VLT/UVES. Abundances were derived for Na, Mg, Si, Ca, Mn, Fe, Ni, Zr an…
