Research have been done in following directions: - Spectral optical observations of Herbig Ae/Be stars with high and moderate spectral resolution. - Synchronous optical photometric and polarimetric observations of UX Ori type stars. - Near Infrared (JHKL) observations of the same stars. Analyzing the data of the long-term photopolarimetric monitoring we found strong evidence for non-spherical dust grains alignment in the disks of WW Vul and UX Ori. A catalog of photo-polarimetric observations of UX Ori - type stars carried out in CrAO in course 20- year monitoring has been compiled, and a classification into four sub-groups is proposed. In 2007-2008 photometric observations of V1184 Tau have been continued. A mechanism of its optical and NIR variability is proposed. It is shown that by the character of variability it may be classified as UX Ori type star, but by the physics of the processes causing the variability it is a FU Ori-like object.
