We continue to present the results of a Byurakan Narrow Band Imaging Survey (BNBIS). In this work we present the results of the search and further detailed investigation of the objects, found in the course of the BNBIS survey in the southern part of the Mon R2 association. For the search of HH objects the narrow band images, obtained with the 1-m Schmidt telescope of the Byurakan Observatory, were used. Newly found objects were imaged in optical and near-IR range with the Apache Point Observatory 3.5 meter telescope, and observed spectrally with long-slit spectrograph and scanning Fabry-Perot interferometer on 6 m telescope of Special Astrophysical Observatory of the Russian Academy of Sciences using SCORPIO-2. We found three new HH groups: HH 1233, HH 1234 and HH 1235, two of them represent extended collimated flows. HH 1233 is the C-shape bipolar outflow system associated with the 2MASS 06084223$-$0657385 source star. HH 1234 is the helical chain of HH knots near the star V963 Mon. HH 1235 is a separate compact knot, connected with the visible only in mid- and far-IR source WISE J060856.57$-$070103.5. We found also several molecular hydrogen outflows, one of which coincides with HH 1233 and two other are associated with the deeply embedded IR sources in the same field. One more probable bipolar H$_2$ outflow is related to WISE J060856.57$-$070103.5. The emission spectra and spectral energy distributions of the source stars were analyzed. According to them they should be under rather early evolutional stage. |
