Scientific paper

We have used Hipparcos epoch photometry and a form of autocorrelation analysis to investigate the amplitude and timescale of the short-period variability of 82 Be stars, including 46 Be stars that were analyzed by Hubert & Floquet using Fourier and CLEAN analysis and 36 other Be stars that were suspected of short-period variability. Our method has given useful information for about 84% of these stars; for the rest, the time distribution of the Hipparcos epoch photometry limits the capability of our technique.
