Spectral Classification of Stars
Spectral classification of stars is a fundamental process in astronomy, crucial for understanding the diverse nature of celestial objects scattered across the cosmos. This method categorizes stars based on the characteristics of their spectra, revealing valuable insights into their temperature, composition, and evolutionary stage. By analyzing the distribution and intensity of light emitted by stars across different wavelengths, astronomers can discern patterns that help classify them into distinct spectral types. This classification system provides a framework for studying stellar populations, deciphering their properties, and unraveling the mysteries of the universe's vast stellar tapestry.
