Deciphering the Origin of Intracluster and Intercluster Inhomogeneities of the CNO Elements Within the Galactic Globular Cluster System

利用球状星团研究早期化学物质 银河系中的富集是不确定的， 同一星团中的恒星， 碳、氮、氧和可能的其它元素。 澄清 这是因为一个系统的化学丰度调查 不同星团中处于不同演化状态的恒星 被制造。 此次调查首次成为可能， 利克天文台新仪器的能力和 位于夏威夷的凯克望远镜。

The use of globular cluster stars to study early chemical enrichment in the galaxy is rendered uncertain by the existence of stars in the same cluster with different surface abundances of carbon, nitrogen, oxygen and possibly other elements. To clarify the causes of this, a systematic survey of the chemical abundances of stars in different evolutionary states in various clusters will be made. This investigation is possible for the first time due to the capabilities of new instrumentation at Lick Observatory and the Keck Telescope in Hawaii.
