Abstract:

We present new results obtained in frames of the Byurakan Narrow Band Imaging Survey (BNBIS). Observations were carried out with upgraded 1 m Schmidt telescope of Byurakan Observatory. Main task of this survey is to search and to study the new Herbig-Haro objects and collimated outflows using narrow-band Hα and [S ii] images of some fields in dark clouds of Galaxy. And, because, Herbig-Haro objects are the main indicators of active starformation processes to fined regions where going on active starformation processes. Main targets of this survey are R associations, young stellar objects associated with compact reflection nebulae, but here we will mainly focused on deeply embedded infrared sources in molecular clouds. During this survey we plan to significantly expand the list of HH objects by using the high quantum efficiency of the system and the telescopes high focal ratio (F/2), which allows detecting low surface brightness objects as well as large field of view of Schmidt telescope.

General note:

Communications of the Byurakan Astrophysical Observatory (ComBAO) is a peer-reviewed scientific journal, which publishes research in observational and theoretical astronomy/astrophysics and presents recent advances in these fields. It is being published by the NAS RA V. Ambartsumian Byurakan Astrophysical Observatory (BAO) in English in electronic form. The journal publishes original papers, review papers, brief reports, book reviews, special communications, observational and theoretical results in various fields of astronomy and related sciences, and some editorial notes, including anniversaries and obituaries. Under the heading “Legacy”, the renewed magazine will republish some old articles of high value in English. The heading “Guest articles” will bring to the attention of readers the articles of researchers who are not employees of BAO. ComBAO was founded in 1946 and regularly published in 1946-1990. However, the publication was interrupted because of the economic situation after the disintegration of the Soviet Union in 1991.
