Studying Stellar Systems with Classical Pulsators

Classical Cepheids and RR Lyrae are very important primary distance indicators and stellar population tracers, thanks to the relations between pulsation properties and intrinsic stellar parameters. Through the theoretical prediction of these relations as well as through the direct comparison between predicted and observed light and radial velocity variations, we are able to constrain the stellar properties of the investigated pulsating stars and their host stellar populations, as well as to study the dependence on chemical composition.
