摘要:

宽视场红外巡天探测器在西圆规分子云中发现了一群年轻的恒星天体。图像显示YSO被聚集成两个主要的群体,这与星云中的暗对流结构相一致。测光分析显示有许多I类和II类天体。这些对象中的几个的位置被发现对应于已知的密集的核心和CO流出。第一类物体往往集中在密集的集合体中,第二类物体在整个区域中分布较为均匀。

英文摘要:

The Wide-field Infrared Survey Explorer has uncovered a population of young stellar objects in the Western Circinus molecular cloud. Images show the YSOs to be clustered into two main groups that are coincident with dark filamentary structure in the nebulosity. Analysis of photometry shows numerous Class I and II objects. The locations of several of these objects are found to correspond to known dense cores and CO outflows. Class I objects tend to be concentrated in dense aggregates, and Class II objects more evenly distributed throughout the region.
