Extract

The β Cep variables are characterised by light variations of a few per cent and velocity variations of up to a few tens of km/s over periods of from about 2.5 to 7 hours. Spectral types range from BO to B2 and luminosity classes from IV to II-III, corresponding to masses from 8 to 18 M ⊙. The light and velocity curves are 90° out of phase, so that maximum light (and also maximum temperature) occur at minimum radius.
