IR源IRAS 16559-2957的光学对应物的详细大气丰度分析

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

R. E. Molina, A. Arellano Ferro

摘要:

我们已经进行了详细的丰度分析的光学对应的红外光源IRAS 16559 -2957,目的是确认其可能的后AGB的性质。这颗恒星显示出太阳的金属丰度,我们对包括CNO和12 C/13 C在内的大量元素的调查表明,该天体经历了第一次挖掘,可能仍处于RGB阶段。

英文摘要:

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.
