| Popis: | We present the results of a narrow-band H and [S II] imaging survey of the star-forming regions in Galaxy. Main tasks of this survey are the search and the studies of the new Herbig-Haro objects and collimated outflows, which are the main indicators of active processes of star formation. Besides, the eruptive stars of very rare types: FUors, EXors, UXors will be searched as well. As the main targets of this survey the R associations, young stellar objects associated with compact reflection nebulae as well as the deeply embedded infrared sources in molecular clouds are selected. Observations are performed with 1-m Schmidt telescope at Byurakan Observatory, which is equipped with modern CCD detector. We plan to significantly expand the list of HH objects by using the high quantum efficiency of this system as well as the telescope's high focal ratio (F/2), which allows detecting low surface brightness objects, and its large field of view. |
