Scientific paper

We carried out a multi-colour time-series photometric study of six stars that were claimed as ''hybrid'' p- and g-mode pulsators in the literature. The β Cep/SPB star γ Peg was confirmed and revealed excellent asteroseismic potential. HD 8801 was confirmed as a ''hybrid'' δ Sct/γ Dor star; additional pulsation frequencies were detected. 53 Psc likely is an SPB star and the O-type star HD 13745 showed small-amplitude slow variability. No light variations were detected for HD 19374 and, surprisingly, ι Her.
