项目摘要

AST 0098548Van AltenaIn a collaborative research project, Dr. William Van Altena, of Yale Southern Observatory, and Dr. Timothy Beers, of Michigan State University, will use the newly installed CCD cameras at the Yale Southern Observatory in Argentina in order to complete the Yale/San-Juan Southern Proper Motion (SPM) program. The first two catalogs of the SPM have already demonstrated the high quality of the absolute proper motions that are attainable within this program. The CCD system will allow completion of the 2nd-epoch observations of the southern sky and, furthermore, will provide the first full southern-sky set of photometry in V and B, down to a magnitude limit of V = 18.0 and B = 19.0. While the first two SPM Catalogs were based on input lists of interesting objects as well as randomly selected stars for kinematic studies, the new CCD camera system, and recent completion of the digitization of all SPM plates by the Precision Measuring Machine of the U.S. Naval Observatory, will allow the new version of the SPM Catalog to be complete to the limiting magnitude of the 1st-epoch plates. The science return from this effort will be enormous! During this award period, about 6000 square degrees, or three-quarters of the remaining SPM fields should be observed and analyzed.The immediate motivation for the project is linked to exploration of the kinematics and dynamics of the Galaxy, using not only randomly selected anonymous stars but also subsets of special interest; primarily the recently completed lists of tens of thousands of metal-poor (MP) and field horizontal- branch/main-sequence A-type (FRB/A) candidate stars obtained from digital scans of the HK survey plates of Beers and colleagues, and the even larger set of interesting targets generated from the stellar component of the Ramburg/ESO Survey. These two surveys form the basis for present spectroscopic exploration of the nature of the early Galaxy and its chemical and dynamical evolution, and hence are of immediate interest. This information will be combined with radial velocities already in hand, or to be obtained from planned large-scale spectroscopic follow-up, in order to determine full space motions for the most interesting targets from the other surveys long before proper motions and distance measurements are obtained with the space missions FAME and SIM.***
AST 0098548货车Altena在一个合作研究项目中,耶鲁南方天文台的William货车阿尔特纳博士和密歇根州立大学的Timothy Beers博士将使用阿根廷耶鲁南方天文台新安装的CCD相机,以完成耶鲁/圣胡安南方自行(SPM)计划。SPM的前两个星表已经证明了在这个程序中可以获得的高质量的绝对自行。 CCD系统将完成对南天的第二历元观测,此外,还将提供V和B的第一套完整的南天测光,直到V = 18.0和B = 19.0的星等极限。虽然前两个SPM星表是根据感兴趣的天体和随机选择的恒星的输入列表进行运动学研究,但新的CCD照相机系统以及美国海军天文台精密测量机最近完成的所有SPM底片的数字化,将使新版SPM星表完整到第一历元底片的极限星等。这项工作的科学回报将是巨大的!在这段授标期间,应观测和分析大约6000平方度,即剩余SPM场的四分之三,该项目的直接动机是探索银河系的运动学和动力学,不仅使用随机选择的匿名恒星,而且使用特别感兴趣的子集;主要是最近完成的数万颗贫金属(MP)和场水平分支/主序星A型(FRB/A)候选星的名单,这些候选星是从Beers及其同事的HK测量板的数字扫描中获得的,以及从拉姆堡/ESO巡天的恒星部分产生的更大的有趣目标。 这两个调查的基础上,目前的光谱探索的性质,早期的银河系及其化学和动力学的演变,因此是直接的利益。这一信息将与已经掌握的径向速度相结合,或与从计划的大规模光谱跟踪中获得的径向速度相结合,以便在FAME和SIM空间飞行任务获得自行和距离测量值之前很久,从其他勘测中确定最感兴趣的目标的整个空间运动。
