| 摘 要： | 利用法国巴黎天文台的南锡射电望远镜对ON2西部区域OH16 12MHz脉泽首次进行观测 ,观测结果表明 ,西部区域的OH16 12MHz脉泽的辐射频谱为典型的单峰结构。结合模型对西部区域的OH16 12MHz脉泽谱线频谱图进行分析和研究。利用薄盘模型 ,得到相应于ON2西部区域的OH16 12MHz脉泽单峰脉泽斑的位置在r =112 .5AU ,Y =7.6AU ,其Keplerian运动速度为Ur=10 .6km s ,Vt =- 9.4km s .

| Abstract: | Using the Nancay radio telescope of Paris Observatory,France, OH 1612MHz maser in the west position of ON2 has been first observed. The observational results indicate that the emission spectrum of the OH 1612MHz in the west position shows a typical structure of single peak. With a model of thin-disk the emission spectrum has been analysed and studied. This paper has obtained the position of maser spot, corresponding to the single peak, at r=112.5AU, Y=7.6AU. Its Keplerian velocity V r =10.6km/s, V t =-9.4km/s. |
