Pulsating A-F Stars

This Chapter provides a brief description of the different classes of pulsating A-F stars emphasising hybrids δ Sct-γ Dor stars. A modelling technique for hybrid δ Sct-γ Dor stars is presented along with the typical features that these stars “print” on their light curves and frequency spectra. Final...
