Dr. Vogel will conduct a research program with this Presidential Young Investigator award which will focus on the application of millimeter and centimeter wavelength astronomy techniques to the study of the interstellar medium and star formation. Three areas will be emphasized: the protostellar collapse phase, the evolution of ultracompact HII regions, and star formation in nearby spiral galaxies. Conclusive evidence for the collapse of an interstellar molecular cloud to make a star has been extremely difficult to obtain. One problem has been that the characteristic signatures of collapse become evident only on the smallest spatial scales, which makes high angular resolution observations essential. Another problem is that other gas motions such as outflow occur as the collapse continues. Dr. Vogel will concentrate on a sample of objects which do not show evidence of masking gas motions, and he will use newly available observational facilities and techniques in an attempt to obtain the elusive direct evidence of a cloud collapsing to form a star.

沃格尔博士将与这位总统进行一项研究计划 青年研究者奖，将侧重于应用 毫米和厘米波长天文技术， 星际介质和星星形成的研究。 三个领域 将强调：原恒星坍缩阶段， 超致密HII区的演化，以及宇宙中星星的形成。 附近的螺旋星系 星际分子坍缩的确凿证据 形成星星的星云是极其难以获得的。 一 问题是，崩溃的特征是 只有在最小的空间尺度上才变得明显，这使得 高角分辨率观测至关重要。 另一个问题 其他的气体运动，如流出， 继续。 沃格尔博士会集中研究 没有显示出掩盖气体运动的证据，他会 利用新的观测设施和技术， 试图获得云的难以捉摸的直接证据 坍缩形成星星。
