Spectral Types
In space and astronautical engineering, spectral types refer to the classification of stars based on their spectral characteristics. This classification is based on the presence of certain absorption lines in the star's spectrum, which are indicative of the star's temperature, luminosity, and chemical composition. The spectral types are labeled with letters, ranging from O (hottest and most massive stars) to M (coolest and least massive stars), with additional subclasses denoted by numbers (0-9) to further refine the classification. Spectral types are important in understanding the evolution and properties of stars, as well as in identifying potential targets for exoplanet searches.
