大麦云云中朝向N11区的分子气体研究

Study of the molecular gas towards the N11 region in the Large Magellanic Cloud

M. Celis Peña, M. Rubio, S. Paron, C. Herrera

摘要:

我们研究了位于大麦云(LMC)东北侧的HII区N11中的三个亚区。我们使用的$^{12}$ CO和$^{13}$ CO J=3- 2的数据观测的阿塔卡马亚毫米望远镜实验(ASTE)的角度和光谱分辨率分别为22 $^{\prime\prime}$和0.11公里秒$^{-1}$。根据$^{12}$ CO J=3- 2和$^{13}$ CO J=3- 2的积分图,我们估计了与每个分区有关的分子云的质量,假定为局部热力学平衡(LTE),大约为$10^4$ M $_\odot$。此外,从上述地图中,我们研究了每个亚区的$^{12}$ CO / $^{13}$ CO积分比,获得8至10之间的值。

英文摘要:

We study three subregions in the HII region N11 which is located at the northeast side of the Large Magellanic Cloud (LMC). We used $^{12}$CO and $^{13}$CO J=3--2 data observed with the Atacama Submillimeter Telescope Experiment (ASTE) with an angular and spectral resolution of 22$^{\prime\prime}$ and 0.11 km s$^{-1}$ respectively. From the $^{12}$CO J=3--2 and $^{13}$CO J=3--2 integrated maps we estimated, assuming local thermodynamic equilibrium (LTE), masses in about $10^4$ M$_\odot$ for the molecular clouds associated with each subregion. Additionally, from the mentioned maps we study the $^{12}$CO /$^{13}$CO integrated ratios for each subregion, obtaining values between 8 and 10.
