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. ***

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 RR 和造父变星距离尺度。 天文学中最重要的两个“标准烛光”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独立的距离估计，进而为产生更遥远星系距离估计的方法提供校准。 凭借这一奖项，布鲁斯·卡尼博士将完成一个项目，其目标是解决基于天琴座 RR 和造父变星校准得出的距离尺度的差异。 数据已经掌握，但需要完成数据缩减，并且需要准备结果以供发布并分发给社区。 ***
