| According to the classification of stellar spectra. Harvard classification is general, spectral types in alphabetical sequence o, b, a, f, g, k, m the order named. Different spectral type, star of various properties of a big difference. Observed stellar spectra, can study the composition and structure of stars, the physical changes in the process of determining the distance of stars to study the stars in the space of movement. 【Spectral types of stars, according to the classification of stellar spectra.
