The period of CY Aquarii.
Abstract
Summary. Published times of maximum light of CY Aquarn have been collected, and used to determine the period of this star by means of the phase-shift method. The period remained constant from t934 to t95t, changed abruptly at that time, and has remained constant since then. Several light curves of CY Aquarii have been analyzed by the maximum entropy method of spectral analysis. The beat period found by Elst has been found to be probably an artifact of his harmonic analysis method. Key words: variable stars period changes
