Observations of Galactic B[e] Stars at the Tien-Shan Observatory

B[e] stars is a group of emission-line early-type stars with large infrared excesses which can be due to circumstellar dust radiation. It contains objects of different physical nature and requires comprehensive observations to understand they intrinsic properties. Very important information about the latters comes from multicolour photometry, however many of the galactic B[e] stars have been rarely observed in the past. We have been performing a photometric study of the northern B[e] stars at a 1-meter Zeiss reflector of the Tien-Shan Observatory in Kazakhstan since 1995. This is a continuation of our program carried out in 1989–1994 which resulted in more than 200 UBV RIJHK observations of 10 objects obtained at the Assy Observatory in Kazakhstan (Bergner et al. 1995).
