摘要：

In this special talk I will give a short lecture for one of the most important class of pulsating stars, the RR Lyrae stars. This class of pulsating stars touches many areas in modern astronomy, ranging from stellar pulsating and evolution to the structure of Galactic halo. In this lectures I will give an overview of RR Lyrae in terms of theoretical (e.g. their pulsation and evolution status) and observational (e.g. their period-luminosity relations and their luminosity-metallicity relations) aspects, some "recipes" to deal with RR Lyrae data (from simple linear regression to machine learning), and some of the unsolved problems. I will end the lecture with the prospect of using ZTF data (and other data) for research related to RR Lyrae, or using RR Lyrae in specific research topics.
