- Аннотация: Classical Cepheids are pulsating supergiants in the main instability strip. In the course of evolution, they move across the instability strip, and their periods vary. Studying theirperiod variations for a time span of several decades, it is possible to determine the rate of secular period increase or decrease, identify the number of instability strip crossing, andthus improve the period--luminosity relation. Special tests are used to determine whether the observed period variation is real or caused by random errors.
