Scientific paper

The authors present results of a continuous five-week photometric campaign on 15 stars in the galactic cluster NGC 3766. Of these stars, one is probably a β Cep variable. Of the seven Be stars observed, four show strictly periodic variations characteristic of the rotation period with indications of unequal maxima and minima. Two others are certainly variable but the amplitudes are too small to derive a period. A spotted star model is suggested as the most likely explanation for the variations.
