天鹅座辫状星云恒星形成区年轻恒星的NEAR-IR光谱
NEAR-IR Spectroscopy of Young Stars in the Braid Nebula Star Formation Region in Cygnus Ob7
摘要：
我们提出了1.4至2.5微米的积分场光谱的16颗恒星的辫子星云恒星形成区域的天鹅座OB7。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一平方度的区域内以前研究不足的林德1003分子云。我们的新光谱数据，结合2MASS近红外测光，提供了许多这些对象在该地区的主序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。
英文摘要：
We present 1.4 to 2.5 um integral field spectroscopy of 16 stars in the Braid Nebula star formation region in Cygnus OB7. These data forms one aspect of a large-scale multi-wavelength survey aimed at determining an unbiased estimate of the number, mass distribution, and evolutionary state of the young stars within this one square degree area of the previously poorly studied Lynds 1003 molecular cloud. Our new spectroscopic data, when combined with 2MASS 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 star forming activity present.
