利用紫金山天文台青海站的13.7 m毫米波望远镜,对NGC 1333/IRAS 6-9附近的一个10.3′ 10′和6.8′ 8′的恒星形成区, 进行了和的成图观测,发现了多个新的分子云核和沿SSV 12IRAS8方向的双极外向流.
本文给出了每个云核的观测特性和物理参数. 分析了这一区域的云核分布和速度场结构. 详细讨论了该区域的云核分布、双极外向流和群集的年轻天体、红外源以及HH天体的关系.

The13CO(1-0)andC18O(1-0) emissions in the NGC 1333/IRAS69 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 and 6.8′ 8′ for , respectively. Several new
compact molecular cores were discovered and a bipolar outflow of was identified along the SSV12IRAS8 direction.
We present the observed properties and derived the physical parameters for all the and 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 indetail.
