IC 5146暗云复合体已在红外线中进行了研究，以识别和研究相关的年轻恒星天体。在调查中发现的大多数物体似乎是场星，主要是晚型巨星。在巡天中发现了三个年轻的天体：B 0星星BD +46 deg 3474，Ae星星BD +46 deg 3471，以及一个先前未被识别的天体，它似乎是一颗被严重遮蔽的FU Orionis星星。最后两个对象的属性进行了详细研究，并试图为他们产生合理的模型。建议FU Orionis星是双星，这个模型的一些结果进行了描述。对IC 5146星团中较亮恒星的光度测量已经被用来确定到该星团的距离为900 +或- 100 pc。
The IC 5146 dark cloud complex has been studied in the infrared in order to identify and study associated young stellar objects. Most of the objects detected in the survey appear to be field stars, predominantly late-type giants. Three young objects were detected in the survey: the B0 star BD +46 deg 3474, the Ae star BD +46 deg 3471, and a previously unidentified object which appears to be a heavily obscured FU Orionis star. The properties of the last two objects are examined in detail, and an attempt is made to produce reasonable models for them. It is suggested that FU Orionis stars are binaries, and some consequences of this model are described. Photometry of the brighter stars in the IC 5146 cluster has been used to establish a distance to the cluster of 900 + or - 100 pc.
