Examples of single sector TESS light curves (left) of β Cep variables of the different light curve sub-classes and their associated periodograms (right). The top light curve is a typical mono-periodic pulsator with a constant pulsation amplitude and a single peak in the frequency spectrum. The second and third panels show multi-periodic pulsators with different lengths of their beating patterns. The bottom panel shows a typical β Cep and SPB hybrid pulsator.
