摘要
利用德令哈观测基地 13.7m毫米波射电望远镜对 Orion B做 13CO( J=1→ 0 )和 C18O( J=1→ 0 )成图观测 .二者均有双极外向流结构 .13CO的 2个方向的外流很不对称 ,中心位置与 CO( J=1→ 0 )外向流大致相同 ,与 CO( J=1→ 0 )外向流相比 ,C18O的外向流中心向北偏移约 1.5′
CO( J =1→0) and C 18 O( J =1→0) maps made with 13 7 m telescope, operating in millimeter waves and placed in Delingha, Qinghai province were revealed the structre of high velocity molecular bipolar outflows. In the 13 CO map the two flows quite near that of CO( J =2→1) map, while the center of C 18 O flows is shifted approximately 1 5′ northwards in contrast to CO( J =1→0) or HCO +( J =3→2) bipolar outflows.
