Abstract:
UBVR photometric monitoring of Herbig Ae/Be stars and some related
objects has been carried out at Maidanak Observatory in Uzbekistan
since 1983. More than 71,000 observations of about 230 stars have been
obtained and are made available for anonymous ftp. Virtually all
Herbig Ae/Be stars observed are irregular variables (called "UXors"
after UX Ori), but there is a wide range of amplitudes from barely
detectable to more than 4mag in V. Our data confirm the results of
previous studies, which indicate that large-amplitude variability is
confined to stars with spectral types later than B8. The distribution
of variability ranges is quite similar to what is seen in classical T
Tauri stars.
