Stellar Abundances in the Galactic Center

AST-9619230银河系中心的恒星丰度。克里斯汀·塞尔格伦博士将在尘埃笼罩的银河系中心发起一项化学进化史的研究。双管齐下的方法将结合30颗银河系中心恒星的高分辨率红外光谱和200多颗银河系中心恒星的中分辨率红外光谱。该项目的目标是测试最近的想法，即从星系盘流入的气体在银河系中心半径200秒差距范围内的分子气体中心区域为持续的恒星形成提供燃料。============================================

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. ============================================
