利用红外天文卫星（IRAS）观测到的天鹅座X区年轻天体的分布，与最近的12 CO（J=2-1）观测相结合。最明亮的年轻恒星对象（YSO）的成员检查本地臂和英仙座臂。远红外，无线电和分子发射也从全球的角度进行了分析。70个YSO已被确认，对应于比ZAMS早的恒星，主要与Local臂中的分子云有关。与这些YSO有关的12 CO（J=2-1）发射揭示了23个宽线翼的实例，其中10个具有空间复杂的扩展高速分子发射
The distribution of young stellar objects toward the Cygnus X region obtained from the Infrared Astronomical Satellite (IRAS) is combined with a recent 12 CO (J=2-1) survey. The most luminous young stellar objects (YSOs) are examined for membership in the Local arm and the Perseus arm. The far-infrared, radio, and molecular emission is also analyzed from a global perspective. Seventy YSOs have been identified, corresponding to stars earlier than ≃B7 ZAMS, primarily associated with molecular clouds in the Local arm. The 12 CO (J=2-1) emission associated with these YSOs reveals 23 instances of broad-line wings including 10 with spatially complex, extended high-velocity molecular emission
