It has an apparent magnitude of and lies at a B dwarfs evolve into giants and may appear at some point as cepheid variables.

Class B also contains the Beta Cephei variables, all giants or sub-giants that pulsate with multiple periods of hours and amplitudes of a few hundredths of a magnitude. Bright examples of B stars include Achernar B5 IV, Regulus B7 V, Rigel B8la and Spica BI In the most luminous class M supergiants (Mu Cephei M2 Iae, VV Cephei M2 Iaep), the emission is related to powerful enveloping winds; such stars are also IRREGULAR VARIABLES.
