The RR Lyrae and Cepheid Variables Distance Scale

北卡罗来纳大学1998财年：24个月40171美元。天琴座RR变星与造父变星的距离比例尺。天文学中最重要的两个“标准烛光”是天琴座RR和造父变星。他们为本星系群中的星系提供了独立的距离估计，这反过来又为产生更遥远星系的距离估计的方法提供了校准。凭借这一奖项，Bruce Carney博士将完成一个项目，其目标是解决基于天琴座RR和造父变星变量校准得出的距离尺度差异。数据到手了，但是需要完成数据缩减，并且需要准备结果以便出版并分发给社区。＊＊＊

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. ***
