Stellar Spectroscopy
Stellar spectroscopy is the study of the interaction between light and matter in stars. It involves analyzing the unique patterns of light emitted or absorbed by stars to determine their chemical composition, temperature, density, and motion. By examining the spectral lines produced by stars, astronomers can gain insight into their physical properties and evolutionary stage. Stellar spectroscopy plays a crucial role in understanding the formation, structure, and evolution of stars in the universe.
