Cno Abundances in the Quintuplet Cluster M Supergiant 5-7
Proceedings of the Galactic Center Workshop 2002(2003)
摘要
We present and analyze infrared spectra of the supergiant VR 5–7, in the Quintuplet cluster 30 pc from the Galactic center. Within the uncertainties, the [C/H], [N/H], and [O/H] abundances in this star are equal to those of α Ori, a star which exhibits mixing of CNO processed elements, but are distinct from the abundance patterns in IRS 7.
