Abstract:

We present long-slit spectroscopy of some new Herbig-Haro objects and outflow systems discovered in the frames of Byurakan Narrow Band Imaging Survey (BNBIS) performed on 1 m Schmidt telescope of Byurakan Observatory. Spectroscopic observations were carried out with 6 m telescope (Russia) using SCORPIO2 spectral camera. All selected objects are associated with deeply embedded infrared sources in the molecular clouds. Long-slit spectroscopy allows to obtain position velocity diagrams of the emission structures like Herbig-Haro objects. Velocity fields of the outflows from IRAS 06277+1016 infrared source in Mon R1, from V963 Mon and 2MASS 06084223-0657385 in Mon R2 as well as from IRAS 06212-1049 are presented. Our spectroscopic data revealed bipolar outflow nature of the outflows associated with 2MASS 06084223-0657385 and IRAS 06212-1049.

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.
