Collaborative Project: Independently Determined Distances to the Magellanic Clouds

合作项目：独立确定到麦哲伦星云的距离。莫菲特博士将与德克萨斯大学的托马斯·巴恩斯博士合作，开展一个观测项目，通过应用于造父变星的表面亮度技术，确定大小麦哲伦星云之间的距离。现有的和新的光度数据将在表面亮度分析中与现有的高质量径向速度相结合，以获得所有22个河外造父变星的单独距离和半径。这些单独的距离将建立到麦哲伦星云的平均距离，独立于其他天体物理距离尺度，也独立于这些造父变星的星际变红。

Collaborative Project: Independently Determined Distances to the Magellanic Clouds. Dr. Moffett, in collaboration with Dr. Thomas Barnes at the University of Texas, will carry out an observational project to determine distances to the Large and Small Magellanic Clouds by means of the surface brightness technique applied to Cepheid variable stars. Existing and new photometric data will be combined with existing high quality radial velocities in a surface brightness analysis to obtain individual distances and radii for all twenty two extragalactic Cepheids. These individual distances will establish mean distances to the Magellanic Clouds independent of other astrophysical distance scales and independent of the interstellar reddening of these Cepheids.
