WebbDepending on the spectral characteristics, stars are designated by a letter from the sequence O, B, A, F, G, K, and M. This spectral sequence is summarized in Table 1. Since temperature controls ionization and excitation of the atoms, this spectral classification basically reflects a temperature sequence.
