Scientific paper

The following suspected Beta Cephei stars have been observed photometrically or rediscussed: HDE 232999, HD 34626, 43818, 43837 and 190467. The first two stars have been found to be Be stars and, like many such stars, they vary in brightness on a time scale of hours. The last three stars are bright giants or supergiants and, like most such stars, they vary in brightness on a time scale of days. The period and amplitude of the photometric variability of these five stars can thus be understood in the general context of stellar variability, even though none of them appears to be a classical Beta Cephei star.
