Cepheids and RR Lyrae stars have played a historic role in the development of astronomy in a general sense. At the beginning of the 20th century, the famous period-luminosity relation played a fundamental role in the discovery of galaxies and the expansion of the universe. The study of the properties of Cepheids and RR Lyrae stars, which is highly interesting, allows us to understand the evolutionary structure of these classes of variable stars. On the other hand, it contributes significantly to the theory of stellar evolution.
