| مستخلص: |
Presents a distance to the variable star, Cepheid Xi Geminorum, which was determined by direct measurement of the changes in its diameter as it pulsates using an optical interferometer. Calibration of the period-luminosity relation, which is necessary to help determine the expansion rate of the Universe (the Hubble constant); Methods and results. |
