Crutcher, RichardUniversity of IllinoisAST-9820641Dr. Crutcher continues his observational study of interstellar magnetic fields. He will measure magnetic field strengths and morphologies in star-forming regions in the Galaxy to provide observational constraints and testing of theoretical models in order to improve understanding of the processes of star formation. He will utilize a variety of radio telescopes to measure the Zeeman effect in selected spectral lines and the linear polarization of dust emission and spectral line emission to yield field strengths as well as field morphologies. His comprehensive observational research program is an important complement to theoretical studies of the evolution of the interstellar plasma and of the star formation process.

Crutcher，RichardUniversity of IllinoisAST-9820641Dr.克拉彻继续他对星际磁场的观测研究。 他将测量银河系恒星形成区域的磁场强度和形态，以提供观测约束和理论模型的测试，从而提高对星星形成过程的理解。他将利用各种射电望远镜来测量塞曼效应在选定的光谱线和线性偏振的尘埃发射和光谱线发射，以产生场强以及场形态。他的综合观测研究计划是对星际等离子体演化和星星形成过程理论研究的重要补充。
