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.

Answer:
access
Explanation:
Managing users' access rights to digital resources within the organization's environment is a fundamental SoD control. As more services are requested by users, utilizing the built-in panels to check compliance with internal controls might become excessive. Companies require a comprehensive Identity Governance and Administration plan to monitor these user access and offer an authoritative source of identity definitions in order to ensure SoD compliance.
They enable interoperability between software and hardware from different vendors.
In order.
