Résumé

The rate of period change due to evolution has been calculated for a ? Cephei star of 16 ?? by means of a theoretical evolutionary track. The dependence of this rate on mass has been estimated. This rate has been compared with observed rates of period change in a few ? Cephei stars. Unfortunately, the uncertainty in the masses of the ? Cephei stars and the possibility of non-evolutionary period changes make it impossible to determine precisely the evolutionary state of these stars. Nevertheless, it is unlikely that they are in the late gravitational contraction or early shell hydrogen burning phases of evolution.
