Abstract
13CO(1-0)and C 18O(1-0)emissions in the NGC 1333/IRAS6–9 star forming region were mapped with the 13.7 m millimeter wave telescope of Purple Mountain Observatory. The areas covered are 10.3′ × 10′ for 13CO(1-0)and 6.8′ × 8′ for C 18O(1-0), respectively. Several new compact molecular cores were discovered and a bipolar outflow of 13CO(1-0)was identified along the SSV12-IRAS8 direction. We present the observed properties and derived the physical parameters for all the 13CO(1-0)and C 18O(1-0)cores. The core distribution and velocity structure are analyzed for this region. The relationship between cores, bipolar outflow and crowded young stellar objects (including infrared sources and HH objects) is also discussed in detail.
