ON2中部以西区域OH1665和1667MHz脉泽的观测和研究

Observation and Study of OH1665 and OH1667 MHz Masers in the West Region of ON2(C)

利用法国巴黎天文台的南锡射电望远镜对ON2中部以西区域OH1665和1667MHz脉泽进行观测,结合模型对中部以西区域的OH1665和1667MHz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中部以西区域的OH1665和1667 MHz峰的脉泽斑的位置及其Keplerian运动速度。

Using the Nancay radio telescope of Paris Observatory,France, OH 1665 and 1667MHz masers in the west region of ON2 have been firstly observed.With a model of thin-disk the emission spectra are analysed and studied. The peak positions of maser spots, and their Keplerian velocities are obtained.
