摘要
在红外天文卫星点源表中选取了具有陡远红外谱的97个源及其它8个红外源,用射电天文联合实验室紫金山天文台青海站的137m望远镜,进行了CO(J=1-0)的观测.结果在102个源中测到了CO辐射,有9个源参考位置难以确定,21个源有多重成分,在其余72个源中有29个具有高速气体,其中18个是新测到的双极外向流候选者,对其性质及与年轻星体的关系作了简要讨论.
From the IRAS PSC 97 sources with steep FIR spectrum and another 8 point sources were chosen to search for high velocity gas.Observations of CO( J =1-0)lines were made with the 13 7 mtelescope at the Qinghai Station of Purple Mountain Observatory,Joint Laboratory for Radio Astronomy.The results show that there are 102 sources associated with molecular gas,9 sources having reference position problems and 21 having multiple spectrum.In the 72 other sources 29 are with high velocity gas,of which 18 are new molecular-outflow candidates.Their properties are discussed briefly in connection with massive young stellar objects.
