Deciphering the Origin of Globular Cluster Light-Element Abundance Inhomogeneities

克拉夫特，罗伯特96-18351克拉夫特博士将使用凯克望远镜和立克3米望远镜进行一项观测计划，以研究球状星团内恒星的某些轻金属的表面丰度。利用丰度数据进行的众多研究中，有一项是关于恒星演化的，它将对深混合的原因以及它是否由恒星自转驱动提供限制。丰度数据还将允许调查球状星团中原始丰度不均匀的程度。***

Kraft, Robert 96-18351 Dr. Kraft will conduct an observational program using the Keck telescope and the Lick 3-m telescope to study the surface abundance of certain light metals for stars within globular clusters. One of the many studies to be conducted with the abundance data is in stellar evolution and will provide constraints on the cause of deep- mixing and whether it is driven by stellar rotation. Abundance data will also allow an investigation of the degree to which primordial abundance inhomogeneities are present in globular clusters. ***
