所有的年轻明星都在哪里?

Where are all the Young Stars in Aquila?

L. Prato, E. L. Rice, T. M. Dame

摘要:

天鹰座裂谷在银河系高经度的一端包含了巨大的天鹰座分子云复合体,然而,在该区域内已知的年轻恒星很少,只有一颗与天鹰座裂谷直接相关。相比之下,位于大裂谷低银河经度端的巨蛇座恒星形成区包含数百颗年轻恒星。我们回顾研究的原始分子材料和描述搜索年轻的对象在天鹰座云。还提供了已知年轻恒星和相关喷流和外流的特征。最后,我们提出了一些可能的解释,在这个富含气体的地区缺乏恒星形成,并提出了一些未来的观察,以进一步研究这个谜。

英文摘要:

The high Galactic longitude end of the Aquila Rift comprises the large Aquila molecular cloud complex, however, few young stars are known to be located in the area, and only one is directly associated with the Rift. In contrast, the Serpens star-forming region at the low Galactic longitude end of the Rift contains hundreds of young stars. We review studies of the raw molecular material and describe searches for young objects in the Aquila clouds. The characteristics of the known young stars and associated jets and outflows are also provided. Finally, we suggest some possible explanations for the dearth of star formation in this gas-rich region and propose some future observations to examine this mystery further.
