Internal Structure and Dynamics in Molecular Cloud Cores with Embedded HII Regions

分子云核心的动力学和物理结构非常重要，因为它们是理解云及其物理和化学演化的关键成分。Helene Dickel博士将研究星际云的速度、温度和密度场，方法是将观察到的不同分子种类跃迁的强度分布与通过模型云计算出的辐射转移的理论分布进行比较。Dickel博士将在剖面中寻找独特的特征，这些特征要么指向特定的动态情况，要么通过它们的存在（或不存在）为特定范围的云参数设定界限。

The dynamics and physical structures in the cores of molecular clouds are important because they are key ingredients for understanding the clouds and their physical and chemical evolution. Dr. Helene Dickel will investigate the velocity, temperature, and density fields of interstellar clouds by comparing observed intensity profiles of different transitions of molecular species with theoretical profiles calculated from the transfer of radiation through a model cloud. Dr. Dickel will be looking for unique signatures in the profiles which either point to a particular dynamical situation or by their existence (or absence) can place bounds on a particular range of cloud parameters.
