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 0098548VAN ALTENAIN是一个合作研究项目，耶鲁大学南部天文台的William van Altena博士和密歇根州立大学的Timothy Beers博士将在阿根廷的耶鲁大学南部天文台上使用新安装的CCD摄像机，以完成耶鲁大学/San-Juan Southern Southern Mortion（Spm）的计划（SPM）。 SPM的前两个目录已经证明了该程序中可实现的绝对适当动作的高质量。 CCD系统将允许完成南部天空的第二段观测值，此外，将在V和B中提供第一套完整的Southern Sky光度法，降至V = 18.0和B = 19.0。虽然前两个SPM目录是基于有趣对象的输入列表以及用于运动学研究的随机选择的星星，新的CCD摄像头系统以及最近通过美国海军观测机的精确测量机对所有SPM平板进行数字化的完成，将允许新版本的SPM Catalog的新版本完整，可以完整地完成1Sts-pecoch of ligitation of ligitation of ligitation of ligitation of ligity of ligity of ligiting of 1st-pecspecoch。从这项工作中回报的科学将是巨大的！在此奖励期间，应观察和分析其余的SPM领域的大约6000平方英尺或四分之三。主要是最近完成的成千上万金属罚款（MP）和现场水平分支/主序列A-Type（FRB/A）候选恒星，这些候选恒星是从啤酒和同事的HK调查板的数字扫描中获得的，以及从RAMB/ESO REMORGE的Stellar组件中产生的更大的有趣目标。 这两项调查构成了对早期星系性质及其化学和动力学进化的本质的当前光谱探索的基础，因此是直接的利益。该信息将与已经掌握的径向速度结合，或者是从计划的大规模光谱随访中获得的，以确定在其他调查中很久以前从其他调查中获得最有趣的目标的完整空间动作，然后才能通过空间任务和SIM模特和SIM模特和SIM。
