The possible multiperiodic variable Be star KY Andromedae

Broad-band UBV photometric measurements of the variable Be star KY Andromedae obtained in September 1982 have been analysed in search of possible periodicity. Periodogram analysis has shown that one dominant period of 0.751 d is present in the data. Further periods are tentatively identified, but possible multiperiodicity will still have to be confirmed with a larger data set. Besides the claimed multiperiodic variations, the color behaviour is also similar to that of non-radial pulsators of the 53 Persei type. At least one other explanation is possible in terms of stellar rotation combined with irregular intrinsic circumstellar variations
