WebbBecause this line‐width classification correlates with luminosity, the designation Ia to V is termed a luminosity class. The full spectral classification of a star therefore includes both the spectral type (OBAFGKM) as well as its luminosity class (I‐V); for example, we would classify the Sun as a G2 V star.
