Résumé

Light, colour and radial velocity variations are calculated for radially oscillating models applicable to ? Cephei stars. Tentative non-radial calculations are also presented. A comparison with published ?V, ?(U–B) and 2K data for these variables is made. The observed $\Delta V/\Delta(U-B)$ data suggest the presence of both radial and non-radial oscillations in the ? Cephei stars. Line profile variations in the star 12 Lac are compared with the predictions of $(l, m)=(2, -2)\,\text{and}\,(2, 0)$ oscillations and a reasonable agreement is obtained. However, a full hydrodynamic treatment of the oscillations will probably be required to obtain satisfactory models of radial velocity variations.
