摘要

This article explores the application of spectroscopy in solar and stellar physics, emphasizing its role in analyzing stellar spectra to determine key physical and chemical properties of celestial bodies, such as their temperature, metallic composition, and intrinsic luminosity. Using archival data from the Sun and three other stars, we demonstrate how absorption lines reveal elemental composition and how Wien’s displacement law can be used to estimate stellar temperatures. Our results highlight the significance of spectroscopy in probing stellar evolution and fundamental astrophysical processes.
