Abstract:
The Hipparcos photometry of the chemically peculiar main-sequence B, A
and F stars are examined for variability. Some non-magnetic CP stars,
Mercury-Manganese and metallic-line stars, which according to
canonical wisdom should not be variable, may be variable and are
identified for further study. Some potentially important magnetic CP
stars are noted.
