INVESTIGATION OF NON-STATIONARY STARS AND GALAXIES

Observations of variable stars in Tajikistan were made from the first days astronomical observatory in Dushanbe. Over the past years a "Sky Survey" has been created, unique photo-archives consisting of almost 70,000 sky negatives. From these some novae and more than 100 variable stars have been discovered in T-associations. 

In addition, some features of light curves, the variability of periods of variables of different types, and oscillations in brightness of novae were studied. With the coming into operation of the Sanglokh 1-m telescope, photometric, polarimetric, and spectrographic observations of faint objects, extremely young stars, as T Tauri and Ae/Be Herbig types, began to be made. Carrying out simultaneous polarimetric and photometric observations in different colors on some stars of the T-Tauri type, scientists of the Institute study physical conditions in the gas-dust shells of these stars.
Theoretical investigations of the dynamical phenomenon of the collective gravitational interactions of stars in galaxies have been widely developed at the Institute. Investigation of star formation in galaxies have shown that spiral waves of density in galaxies were active in producing not only the features of motion of stars and interstellar gas, but also the peculiarities of late star-formation processes.
