MOLINA, R. E.  and  ARELLANO FERRO, A.. Detailed atmospheric abundance analysis of the optical counterpart of the IR source IRAS 16559-2957. Rev. mex. astron. astrofis [online]. 2013, vol.49, n.1, pp.101-109. ISSN 0185-1101.

We have undertaken a detailed abundance analysis oí 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.

Keywords : stars [abundances]; stars [AGB and post-AGB]; stars [evolution].
