摘要
利用VLBⅠ MKⅢ记录系统,在1665和1667 MHz跃迁频率上,观测活动恒星形成区NGC 6334F的左右圆偏振羟基(OH)脉泽分子辐射;介绍了VLBIOH分子谱线观测过程,给出了基本的观测结果,并对结果作了简要地分析和讨论.
Hydroxyl maser emissions associated with a star formation region NGC 6334F in right and left polarizations at the 1665 and 1667 MHz transitions are observed with VLBI MKIII recording system. It is found that in the region, the strong Hydroxyl maser emissions come from an area of a scale 5×1015cm. The majority of Hydroxyl maser features are projected onto the core of cometary HII region. The velocity gradiant 6-10 km/s/arcsec is found in the velocity-position plot. This suggests that there may be a rotating disk in which a young OB star is formed with mass -25M⊙.
