AST 9529454 Discovery and Analysis of Extremely Low Metallicity Stars, Horizontal-Branch Stars, and A-Type Stars in the Galaxy. Dr. Beers will continue a research program of studying a large sample of very metal poor stars. Such research is valuable for knowledge about nucleosynthesis, the distribution of elements in metal poor stars, and gradients across our Galaxy in the colors of horizontal-branch stars. Obtaining the stellar distribution function in metallicity, kinematics, and space is a good way to try to understand the formation and evolution of the Galaxy. ===========================================

AST 9529454 银河系中极低金属量星、水平分支星和A型星的发现和分析。 比尔斯博士将继续研究大量贫金属恒星的研究项目。 这样的研究对于了解核合成、贫金属恒星中元素的分布以及银河系中水平分支恒星颜色的梯度是很有价值的。 获得恒星在金属丰度、运动学和空间上的分布函数是试图理解银河系形成和演化的一个好方法。 ===========================================
