Abstract: The exploration of stellar pulsations is crucial for gaining insights into the internal structures of stars. Our research focuses on conducting an in-depth asteroseismic and spectroscopic analysis of A- and F-type chemically peculiar stars using both ground-based and space-based observations. By combining photometric and spectroscopic data of these unique stars, we aim to establish a deeper understanding of how stellar activity (such as rotation, magnetic fields, and peculiarities) relates to their oscillations. Additionally, investigating stars within open clusters provides an independent method for determining their fundamental properties. Consequently, our work involves the identification of variable stars within open clusters. In this presentation, I will share the outcomes of our two ongoing projects. The first project involves the investigation of an intermediate-age open cluster, NGC 2126, which hosts numerous short-period pulsating stars. The second project is a detailed analysis of the CP2 star HD 100357. This star exhibits potential signs of low-frequency pulsational variability, which demands a detailed examination.
