AST 9619628 Collaborative Project: Galactic Stellar Populations: Chemistry, Kinematics, & Chronology. Dr. Bruce Carney, University of North Carolina, and Dr. John Laird, Bowling Green University, will carry out a three part observational project relevant to the study of the structure of our Galaxy. The first part is to study the relationship between the thick and thin disks of the Galaxy by analyzing three old- star samples, each of which has more than 1000 stars. The second part is to study the outer disk by obtaining the ages and compositions of stars in the southern Galactic warp. The third part is to study abundance patterns in stars with composition differences among representative halo stars. ========================================

合作项目：银河系恒星群：化学、运动学和年代学。北卡罗来纳大学的布鲁斯·卡尼博士和鲍灵格林大学的约翰·莱尔德博士将开展一个由三部分组成的观测项目，研究我们银河系的结构。第一部分是通过分析三个有1000多颗恒星的老恒星样本，研究银河系的厚盘和薄盘之间的关系。第二部分是通过获得银河系南部翘曲恒星的年龄和组成来研究外盘。第三部分是研究具有代表性的晕星组成差异的恒星的丰度模式。========================================
