Astrometric Research at the Yale University Observatory

耶鲁大学天文台的天体测量研究。Van Altena博士将继续在耶鲁大学进行广泛的当前和计划中的长期天体测量研究。该合同将为减少南方固有运动调查的数据提供一些支持，但主要目标是支持那些与PI在康涅狄格州纽黑文的设施密切相关的操作。Van Altena博士计划制作一份从南半球观测到的暗淡恒星赤经赤纬目录，用于大型望远镜确定暗淡的星系外天体的位置，以及为光谱仪定位光纤探测器。工作将继续进行，以确定对天体物理学感兴趣的选定恒星的视差，并确定星团中可靠的固有运动成员。

Astrometric Research at the Yale University Observatory. Dr. Van Altena will continue a wide range of current and planned long term astrometric research based at Yale University. This award will provide some support for the reduction of data from the Southern Proper Motion Survey, but the principal objective is to support those operations that are closely related to the PI's facilities in New Haven, CT. Dr. Van Altena plans to produce a catalog of Right Ascensions and Declinations for faint stars seen from the Southern Hemisphere for use with large telescopes in determining positions of faint extra-galactic objects and positioning fiber optic probes for spectrographs. Work will continue on the determination of parallaxes of selected stars of astrophysical interest and on determination of reliable proper motion memberships in stellar clusters.
