Panels a–c: the ¹³CO J = 1− 0 emission in blue contours overlaid on the Herschel 250 μm emission in grayscale. The integrated-velocity ranges are shown on top of each image. The green circles represent the 870 μm dust cores, while the red dashed circle shows the position and size of G17.037+0.320 H II region from Anderson et al. (2014). The red arrow may present the shock direction. The two white dashed boxes indicate the compact region with six dust cores. Panel d: the ellipses also mark the positions, sizes, and position angles of the 870 μm dust cores, which are given in Table 1. The different colors mark the cores with different temperatures (T). If T > 24 K, the cores are marked in red, for 10 K < T < 24 K and T < 10 K in pinkand blue, respectively.
