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. ***

Kraft，Robert罗伯特·卡夫96-18351 克拉夫特博士将利用凯克望远镜和利克3米望远镜进行一项观测计划，研究球状星团内恒星表面某些轻金属的丰度。 将利用丰度数据进行的许多研究之一是恒星演化，并将对深层混合的原因及其是否由恒星旋转驱动提供限制。 Abstract数据还将允许调查原始丰度不均匀性在球状星团中存在的程度。 ***
