论文摘要
我们介绍了确定年龄，氦质量分数（y），金属性（[Fe/h]）的结果，以及元素C，N，O，Na，Mg，Ca，Ca，Ti，Ti，Ti，Ti，C和Mn的元素，用于将其中等分辨率集成的scheprim sepsation和Schiavon库中的中等分辨率集成的谱图和我们的群体库中的组合库和我们的群体库中的群体和我们的群体库来进行。我们为我们的分析选择了进化等异隆和恒星质量函数，这为观察到的Balmer线谱的形状和强度提供了最佳近似。确定的元素丰度，年龄和金属性是银河凸起中恒星种群的特征。
We present the results of determination of the age, helium mass fraction (Y), metallicity ([Fe/H]), and abundances of the elements C, N, O, Na, Mg, Ca, Ti, C and Mn for the Galactic globular cluster NGC 6652. We use its medium-resolution integrated-light spectrum from the library of Schiavon and our population synthesis method to fulfill this task. We select the evolutionary isochrone and stellar mass function for our analysis, which provide the best approximation to the shapes and intensities of the observed Balmer line profiles. The determined elemental abundances, age and metallicity are characteristic of stellar populations in the Galactic Bulge.
