RESUMEN

Hemos emprendido un análisis detallado de las abundancias químicas de la contraparte óptica de la fuente infrarroja IRAS 16559–2957 con el fin de confirmar su posible naturaleza de estrella post–AGB. El análisis de un gran número de elementos, incluidos CNO y ¹²C/¹³C, muestra que este objeto ha experimentado el primer dragado y parece estar aún en fase de RGB.

 

ABSTRACT

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.

Key Words: stars: abundances — stars: AGB and post–AGB — stars: evolution.
