The rates of change of the periods of SX Phe.
Abstract
Changes in the periods of the double-mode beat cepheid star SX Phe from 1951 to 1987 deduced from observed times of maximum light are presented. The mean level of the sinusoidal beat curve with (O-C) values assuming a constant fundamental period, plotted against the year of observation, is illustrated.
