我们介绍了红MSX源调查，这是迄今为止统计上选择的最大的年轻大质量原恒星和H区目录。我们概述了使用中红外和近红外颜色选择的目录结构。我们还讨论了其他波长的详细后续工作，包括更高空间分辨率的红外数据。我们表明，在采用的选择范围内，我们完成了90%以上的大质量原恒星群，激发源的位置精度优于2弧秒。我们简要总结了从整体上研究星表中天体的性质所能得到的一些结果；我们发现的证据表明，质量最大的恒星形成：(1)优先靠近银河系中心，而不是反中心；(2)在最严重的红化环境中，表明高吸积速率；(3)来自最大质量的云核。
We present the Red MSX Source survey, the largest statistically selected catalog of young massive protostars and H ii regions to date. We outline the construction of the catalog using mid- and near-infrared color selection. We also discuss the detailed follow up work at other wavelengths, including higher spatial resolution data in the infrared. We show that within the adopted selection bounds we are more than 90% complete for the massive protostellar population, with a positional accuracy of the exciting source of better than 2 arcsec. We briefly summarize some of the results that can be obtained from studying the properties of the objects in the catalog as a whole; we find evidence that the most massive stars form: (1) preferentially nearer the Galactic center than the anti-center; (2) in the most heavily reddened environments, suggestive of high accretion rates; and (3) from the most massive cloud cores.
