| Abstract: |
Linear nonadiiabatic calculations for models of B-type pulsators predict many more unstable modes than actually observed, therefore a mode selection mechanism must operate in these stars. To investigate this problem quantitatively, available data for singly periodic and multi periodic β Cephei variables are compared. No clear cut differences are found. The slight difference in [m/H], noted recently by Daszynska et al. (2003), may indicate the solution. |
