,Importance of studying β Cephei stars in open clusters and associations,Beta Cephei stars which are located in clusters and associations can be used to gather information on their evolutionary phase when they are placed on the color magnitude diagram. A tentative study is presented which attempts to use this idea to answer several important questions concerning B Cephei stars.

,δ Scuti variables: The link between giant- and dwarf-type pulsators,ables. Results of linear stability studies for d Scuti stars are reviewed and supplemented with new calculations. The function of the opacity mechanism in generating instability to a variety of radial and nonradial modes is discussed. The highest excitation rates for these variables, though still mu

,Nonlinear δ Scuti models: The main sequence catastrophe?,meters. Models with limited viscosity attain huge amplitudes. Furthermore, it is found that nonlinear stability properties depend primarily upon the amplitude. Determination of the actual dissipation mechanism is thus crucial to our understanding of these objects, and probably other main sequence pu
