Detailed atmospheric abundance analysis of the optical counterpart of the IR source IRAS 16559-2957    [PDF]

R. E. Molina, A. Arellano Ferro

We have undertaken a detailed abundance analysis of the optical counterpart of the IR source IRAS16559-2957 with the aim of confirming its possible post-AGB nature. The star shows solar metallicity and our investigation of a large number of elements including CNO and 12C/13C suggests that this object has experienced the first dredge-up and it is likely still at RGB stage.
