A luminosity sequence illustrating the properties of spectral type B8. The B8 Ia supergiant β Ori (Rigel) is the anchor standard. All the stars shown are slow rotators, except for 27 Tau, included so that the pair of giant standards illustrate the effects of rotation. The SB2 nature of 27 Tau is not perceived at this resolution. See Fig. D.3 for examples of fast rotating B8 V stars.
