描述天鹅座X区域的外流

Characterizing Outflows in the Cygnus X Region

Soumen Deb, Roland Kothes, Erik Rosolowsky

摘要:

本文分析了天鹅座X星形成区的13个外流。我们使用詹姆斯克拉克麦克斯韦望远镜观测到的$^{13}$ CO(3-2)和C $^{18}$ O(3-2)分子发射线,结合档案$^{12}$ CO(3-2)数据。利用这些新的观测结果,我们测量了流出物的力学性质,并确定了相关的原恒星,发现它们的性质与以前对整个银河系流出物的调查一致。最后,我们开发并测试了一种方法来测量相同的属性,单独使用现有的$^{12}$ CO(3-2)线数据,发现属性同意在一个因素2。

英文摘要:

In this paper, we perform an analysis of 13 outflows in the Cygnus X star-forming region. We use the James Clerk Maxwell Telescope observations of $^{13}$CO(3-2) and C$^{18}$O(3-2) molecular emission lines combined with archival $^{12}$CO(3-2) data. Using these new observations, we measure the mechanical properties of the outflows, and identify the associated protostars, finding their properties consistent with previous surveys of outflows throughout the Milky Way. Finally, we develop and test a method to measure the same properties using the existing $^{12}$CO(3-2) line data alone, finding the properties agree to within a factor of 2.
