标题： Star clusters in the Sh2-132 complex: clues about the connection between embedded and open clusters

摘要： 嵌入星团形成于分子云中，在那里大质量恒星可以产生电离氢区（HII区）。嵌入式-疏散星团演化连接的详细情况以及星协的起源仍有待揭示。嵌入星团似乎有很高的婴儿死亡率，而少数幸存者则演化为疏散星团。 我们利用2MASS数据库研究了与Sh2-132 HII区相关的星团的颜色-亮度图和结构。 我们发现了四个星团。 其中一个投影位置距离光学星团Teutsch 127几个直径远，并且看起来深深嵌入其中，仅在红外波段可见。 我们发现证据表明，我们正在见证从嵌入星团向疏散星团的动力学转变。 另一个额外的星团也靠近Teutsch 127，可能与弓形激波有关。 我们还研究了Sh2-132中疏散星团Berkeley 94和投影在复杂外围的一个新星团的颜色-亮度图和结构。 最后，我们在该复合体中的两个已知沃尔夫-拉叶星周围寻找了星团。 其中一个似乎与一个紧凑星团有关。 最后，目前的分析表明年轻星团的早期动力学演化。 显示英文摘要

摘要： Embedded clusters are formed in molecular clouds where massive stars can produce HII regions. The detailed embedded-open cluster evolutionary connection as well as the origin of associations are yet to be unveiled. There appears to be a high infant mortality rate among embedded clusters and the few survivors evolve to open clusters. We study the colour-magnitude diagrams and structure of the star clusters related to the Sh2-132 HII region using the 2MASS database. Cluster fundamental and structural parameters are determined via MS and PMS isochrones and stellar radial density profiles. We report the discovery of four clusters. One of them is projected a few diameters away from the optical cluster Teutsch\,127 and appears to be deeply embedded, seen only in the infrared. Evidence is found that we are witnessing the dynamical transition from an embedded to an open cluster. An additional cluster is also close to Teutsch\,127 and might be associated with a bow-shock. We also study the CMD and structure of the open cluster Berkeley\,94 in Sh2-132 and a new cluster which is projected in the outskirts of the complex. Finally, we searched for star clusters around the two known Wolf-Rayet stars in the complex. One of them appears to be related to a compact cluster. Finally, the present analyses suggest early dynamical evolution for young star clusters.
