True, RR Lyrae stars pulsate, but with shorter periods and lower luminosities than Cepheids.

The pulsation periods of the fundamental-mode RR Lyrae stars range from about 0.3 to 1.0 days (Population II pulsators with longer periods are categorized as type II Cepheids), but the vast majority of them have generations longer than 0.45 days.

<h3>Why do RR Lyrae stars pulsate?</h3>

RR Lyrae stars pulse like Cepheid variables, but the nature and histories of these stars is thought to be rather different. Like all variables on the Cepheid fluctuation strip, pulsations are caused by the κ-mechanism, when the ambiguity of ionised helium varies with its temperature.
