Özet
(Session: Cool Stars in the Context of Cosmic Evolution)
Bulge globular clusters provide important information about the early formation stages and chemical evolution of the Milky Way. However, due to increasing interstellar extinction and high stellar
density toward the galactic bulge, detailed observational studies of these clusters are limited. Consequently, many bulge globular clusters remain unexplored, with only a few having had their elemental
abundances reported. In this study, we present the chemical abundance analysis results for the bulge
globular cluster NGC 6558. For this analysis, we used high-resolution APOGEE H-band spectra of
confirmed member stars of NGC 6558 to determine up-to-date stellar atmospheric parameters and
the abundances of C, N, O, and Ce through standard spectroscopic techniques. Additionally, we will
compare the C, N, O, and Ce elemental abundances of the NGC 6558 member stars to those of Galactic bulge field stars. We will apply the same methodology to other program bulge globular clusters to
better understand the chemical characteristics of bulge globular clusters in the galaxy.
