Massive stars have a tremendous impact on their environment. By their important mechanical and radiative feedback their can significantly change the physical conditions of the molecular clouds in which they, and other stars, form. The goal of this project is to perform a detail study of some massive star forming infrared dark clouds where we have indication of stellar feedback at a very early stage. By assuming that the dark parts of the clouds are representative of the initial conditions one can evaluate what the exact impact of feedback on the gas properties.

大质量恒星对它们的环境有巨大的影响。通过它们重要的机械和辐射反馈，它们可以显著改变它们和其他恒星形成的分子云的物理条件。这个项目的目标是对一些形成红外暗云的大质量恒星进行详细研究，我们在非常早期的阶段就有恒星反馈的迹象。通过假设云的暗部分代表初始条件，可以评估反馈对气体性质的确切影响。
