Abstract: We present new radio observations of molecular lines in the region of high mass star formation, namely G122.0-7.1. A large-scale map of the emission observed in the 12CO (J = 1-0) and 13CO (J = 1-0) lines covers the area of 15'×9', revealing two dense regions. The molecular bipolar outflows have been resolved in ASO1 region. It is associated with the known candidate YSO nearby IRAS 0042+5530. Also, a new dense region has been discovered in the North-Western part of the G122.0-7.1 at a distance of 5' from IRAS 0042+5530. Its position is close to the peak of 4850 MHz emission. |
