Abstract

This is a shortened version of the presentation at the conference “Non-Stationary Processes in the Protoplanetary Disks and Their Observational Manifestations” held at the Crimean Astrophysical Observatory.


We present narrow-band images of the southern part of the Mon R2 association obtained in the course of the BNBIS survey with the 1-m Schmidt telescope of the Byurakan Observatory. The main task of this survey is search and study of new Herbig-Haro (HH) objects and collimated outflows using the narrow-band Hα and [S ii] images of certain fields in dark clouds of the Galaxy since the presence of HH objects is one of the main indicators of active star-formation processes.


Several new HH objects and outflow systems were discovered, including the helical chain of HH objects near IRAS 06068-0643 (V963 Mon) and the curved outflow system associated with the 2MASS 06084223-0657385 source, which probably represents the irradiated giant outflow. Also, two molecular hydrogen outflows associated with deeply embedded IR sources near the 2MASS 06084223-0657385 region were revealed.
