摘要

我们报道了恒星形成区W51在11pc尺度上的亚毫米观测，分辨率为0.7 pc。这些观测显示，至少有9个发射中心，每一个都有足够的亮度，成为大质量恒星形成的潜在场所。我们还在这些发射中心周围发现了一个扩展的发射区域。这种扩展的发射成分具有更陡峭的亚毫米光谱，表明它比恒星形成的核心更温暖。

Submillimeter images of W51

We report on submillimeter observations of the star forming region W51 on 11 pc size scales with 0.7 pc resolution. These observations show at least nine emission centers, each of which has enough luminosity to be a potential site for massive star formation. We also detect a region of extended emission surrounding these emission centers. This extended emission component has a steeper submillimeter spectrum, suggesting that it is warmer than the star forming cores.
