本文给出了天鹅座OB 7中辫状星云星星形成区16颗恒星的1.4-2.5 μm积分场光谱。这些数据形成了一个大规模的多波长调查的一个方面，旨在确定一个公正的估计的数量，质量分布，和演化状态的年轻恒星在这1度2以前研究不足的林德1003分子云的区域。我们的新光谱数据，当与两微米全天空调查近红外测光相结合时，提供了许多这些对象在该地区的主序前人口的成员资格的证据。我们讨论了在该地区发现的年轻恒星的特点和恒星形成活动的水平。
We present 1.4–2.5 μm integral field spectroscopy of 16 stars in the Braid Nebula star formation region in Cygnus OB7. These data form one aspect of a large-scale multiwavelength survey aimed at determining an unbiased estimate of the number, mass distribution, and evolutionary state of the young stars within this 1 deg 2 area of the previously poorly studied Lynds 1003 molecular cloud. Our new spectroscopic data, when combined with Two Micron All Sky Survey near-IR photometry, provide evidence of membership of many of these objects in the regions' pre-main-sequence population. We discuss both the characteristics of the young stars found in the region and the level of starforming activity present.
