The RR Lyrae and Cepheid Variables Distance Scale

北卡罗来纳州布鲁斯·卡尼大学98财年：24个月40,171美元。天琴座和造父变星的距离刻度。天文学中最重要的两个“标准蜡烛”是天琴座RR变星和造父变星。它们为本星系群中的星系提供了独立的距离估计，进而为为更遥远的星系提供距离估计的方法提供了校准。有了这个奖项，布鲁斯·卡尼博士将完成一个项目，目标是解决基于RR、天琴座和造父变星校准得出的距离标度的差异。数据在手，但需要完成数据归约，需要准备发布结果并分发给社区。***

Bruce Carney University of North Carolina FY 98: $40,171 For 24 months. The RR Lyrae and Cepheid Variables Distance Scale. Two of the most important "standard candles" in astronomy are the RR Lyrae and Cepheid variables. They provide independent distance estimates for galaxies in the Local Group, which in turn provide the calibrations for methods that yield distance estimates for much more remote galaxies. With this award Dr. Bruce Carney will complete a project with the goal of resolving differences in the distance scales derived on the basis of calibration of RR Lyrae and Cepheid variables. The data are in hand, but the data reduction needs to be completed, and the results need to be prepared for publication and distributed to the community. ***
