中文摘要
AST 9988156 dry博士北卡罗来纳州大学的布鲁斯卡尼和州立大学绿色州立大学的约翰莱尔德博士正在进行一系列观测项目,旨在揭示我们银河系的薄盘、厚盘和晕星星群是如何聚集在一起的。 对于晕族,他们将研究正常和极端速度场恒星中的s-过程和r-过程丰度,这些恒星是在他们最近完成的高自行恒星调查中确定的。 对于厚盘,他们将测量恒星的径向速度和金属丰度,以更清楚地了解三维运动和银河系轨道与金属丰度之间的关系。 对于薄盘,他们将获得贫金属和富金属恒星的光谱,以便与厚盘恒星进行直接比较。 从这些数据集中,这些研究人员将获得一个均匀研究的样本,从中可以更清楚地了解这些恒星种群的化学演化。 ***
英文摘要
AST 9988156CarneyDr. Bruce Carney at the University of North Carolina and Dr. John Laird at Bowling Green State University are pursuing a series of observational projects which are meant to reveal how the thin disk, the thick disk, and the halo star populations of our Galaxy were assembled. For the halo population, they will study s-process and r-process abundances in normal and extreme velocity field stars that were identified in a survey of high proper motion stars they recently completed. For the thick disk, they will measure stellar radial velocities and metallicities to obtain a clearer view of the relation between three-dimensional motions and Galactic orbits with metallicity. For the thin disk, they will obtain spectra of metal-poor and metal-rich stars for direct comparison with the thick disk stars. From the data sets, these investigators will obtain a homogeneously studied sample from which to achieve a much clearer view of the chemical evolution of these stellar populations. ***
