The Impact of a Newly Formed O Star on its Environment

O型星在星系的能量学中起着至关重要的作用， 星际介质，但它们的形成和早期演化 不太了解。 丘奇韦尔是研究 这些物体，将调查新形成的O- 利用高分辨率无线电和红外技术的恒星， 开发模型以了解气体的复杂结构 形成这些物体的云。 模特们将在 通过他们对分子和原子线的预测进行了测试， 在这些云层中可以观察到。 亲属距离和 还将获得其中一些物体的自行。

O-stars play a crucial role in the energetics of galaxies and the interstellar medium, but their formation and early evolution are poorly understood. Churchwell, a world leader in the study of these objects, will investigate the environments of newy formed O- stars utilizing high-resolution radio and infrared techniques, to develop models to understand the complex structure of the gas clouds from which these objects are formed. The models will be tested by their predictions of molecular and atomic lines which would be observable in these clouds. Kinematics distances and proper motions will also be obtained for some of these objects.
