| Abstract: |
A list is presented of the beta Cephei stars in which long-term variations of the pulsation amplitudes and/or frequencies have been detected or found to be below the detection threshold. Then the case of 16 (EN) Lacertae is considered in some detail. The recent interpretation of the long-term amplitude variations of the starUs three strongest pulsation modes is verified using new data. Finally, the cases of long-term variations which lack satisfactory explanation are briefly commented upon. |
