论文摘要
我们提供了G133.50+9.01的引人注目的观察证据，是带有诱导细丝，核心和簇形成的签名的真正的云云碰撞候选者。 CO分子线观测表明，G133.50+9.01复合物由两个碰撞的分子云，具有全身速度，-16.9 km S -1和-14.1 km S -1。云的交集的特征是碰撞的特征广泛的桥接特征。相互作用前面的冲击层的形态类似于弧形结构，并具有增强的激发温度和H2柱密度。在水肺850μm图像中检测到了一个复杂的细丝网络，并具有14个嵌入式密集芯，它们与冲击层的空间相关。通过确定的I类和II类年轻恒星物体的过度密度揭示的恒星簇位于弧形区域的弧形区域，并以可能的碰撞引起的起源佐证。
We present compelling observational evidence of G133.50+9.01 being a bona fide cloud-cloud collision candidate with signatures of induced filament, core, and cluster formation. The CO molecular line observations reveal that the G133.50+9.01 complex is made of two colliding molecular clouds with systemic velocities, -16.9 km s-1 and -14.1 km s-1. The intersection of the clouds is characterised by broad bridging features characteristic of collision. The morphology of the shocked layer at the interaction front resembles an arc like structure with enhanced excitation temperature and H2 column density. A complex network of filaments is detected in the SCUBA 850 μm image with 14 embedded dense cores, all well correlated spatially with the shocked layer. A stellar cluster revealed through an over-density of identified Class I and II young stellar objects is found located along the arc in the intersection region corroborating with a likely collision induced origin.
