AST-9619230 Stellar Abundances in the Galactic Center. Dr. Kristen Sellgren will initiate a study of the chemical evolution history in the dust-obscured center of the Milky Way galaxy. A two-pronged approach will combine high resolution infrared spectra of 30 Galactic Center stars with moderate resolution infrared spectra of more than 200 Galactic Center stars. The goal of the project is to test recent ideas that inflowing gas from the disk of the Galaxy fuels sustained star formation in a central zone of molecular gas which is within a radius of 200 parsecs of the Galactic Center. ============================================

AST-9619230 银河系中心的恒星丰度。 Kristen Sellgren博士将开始研究银河系尘埃遮蔽中心的化学演化历史。 一个双管齐下的方法将结合联合收割机的高分辨率红外光谱的30个银河系中心的恒星与中等分辨率红外光谱的200多个银河系中心的恒星。 该项目的目标是测试最近的想法，即从银河系圆盘流入的气体在银河系中心半径200秒差距内的分子气体中心区持续形成星星。 ============================================
