This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).Dr. Thomas Troland of the University of Kentucky will undertake an extensive radio survey to measure the strengths of magnetic fields in regions of star formation. He will explore the role of magnetic fields in the evolution of molecular clouds, which are cool, relatively dense portions of the interstellar medium containing dust and molecules of hydrogen, carbon, etc. He will also investigate how magnetic fields may interact with very dense gaseous clumps, to see whether these fields may differ when high-mass and low-mass stars are formed. This work will be performed using radio astronomy facilities in West Virginia, Puerto Rico, and Spain.The project will have many implications for the theory of star formation. Dr. Troland will involve students in all aspects of this program, including obtaining, analyzing, and disseminating the data. He will also build on his previous experience in K-12 outreach efforts, and will develop a program to address core concepts in the science curricula for the state of Kentucky.

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。肯塔基大学的Thomas Troland将进行一项广泛的无线电调查，以测量恒星形成区域的磁场强度。他将探索磁场在分子云演化中的作用。分子云是星际介质中温度较低、密度相对较大的部分，含有尘埃和氢、碳等分子。他还将研究磁场如何与非常密集的气体团块相互作用，看看当高质量恒星和低质量恒星形成时，这些磁场是否会有所不同。这项工作将利用西弗吉尼亚州、波多黎各和西班牙的射电天文设施进行。这个项目将对恒星形成理论产生许多影响。Troland博士将让学生参与这个项目的各个方面，包括获取、分析和传播数据。他还将以他以前在K-12推广工作中的经验为基础，为肯塔基州制定一个解决科学课程核心概念的计划。
