In stellar research, spectroscopy and photometry play a key role in obtaining complex insights into stellar properties and processes. Our study focuses on the analysis of spectroscopic data obtained from the Global Astrophysical Telescope System (GATS) for selected Galactic Cepheids. We determined changes in atmospheric parameters and chemical composition in relation to the pulsation phase. To complete our study, we also analyzed photometric data collected by the TESS space observatory. The combination of spectroscopy and photometry provides a more comprehensive understanding of Cepheids and their characteristics.
