Scientific paper

BV photometry was used to observe the light curve, maximal amplitude and orbital period of seven Ap stars (all components of spectroscopic binary systems) with HD classifications - 11529, 27295, 147869, 173524, 182381, 183056 and 196133. Amplitudes were found to be less than 0.025 for all cases and there was no observed light variation with respect to orbital period for any of the stars.
