项目摘要

AST-0606822INSTITUTION: University of Illinois at Urbana ChampaignPI: Richard CrutcherTITLE: Observations of Magnetic Fields in Molecular Clouds: Testing Star Formation TheoryABSTRACTDr. Richard Crutcher, at the University of Illinois at Urbana-Champaign, will continue his long-term research program aimed at observing magnetic fields in molecular clouds to test star formation theory. For magnetically driven low-mass star formation, Dr. Crutcher will test the basic principle that the ratio of the mass to the magnetic flux increases from a molecular cloud envelope to the core. He will also study the role of magnetic fields in high-mass star formation, by carrying out measurements of magnetic field strengths in dense high-mass star formation regions called "Infrared Dark Clouds". Finally, he will use the improvement in observing speed of the James Clerk Maxwell Telescope (JCMT), with the "Submillimetre Common-User Bolometer Array 2" (SCUBA2) instrument, to carry out a survey of dust polarization in starless cores.The research will have broader impact through dissemination by means of invited talks at international meetings, review articles in conference proceedings, articles in monograph chapters, and papers in refereed journals. Dr. Crutcher will also establish a web site to provide an educational and a research resource on cosmic magnetic fields. The research project will involve undergraduates and a graduate student.

AST-0606822机构：伊利诺伊大学厄巴纳香槟分校PI：理查德Crutcher标题：分子云磁场的观测：测试星星形成理论。伊利诺伊大学厄巴纳-香槟分校的理查德·克鲁彻将继续他的长期研究计划，旨在观察分子云中的磁场，以检验星星形成理论。对于磁驱动的低质量星星形成，Crutcher博士将测试从分子云包层到核心质量与磁通量之比增加的基本原理。他还将研究磁场在大质量星星形成中的作用，方法是测量被称为“红外暗云”的密集大质量星星形成区域的磁场强度。最后，他将利用詹姆斯·克拉克麦克斯韦望远镜（JCMT）观测速度的改进，利用“亚毫米通用辐射热计阵列2”（SCUBA 2）仪器，对无星核中的尘埃偏振进行调查。这项研究将通过国际会议邀请演讲、会议论文集评论文章、专题章节文章、和论文发表在权威期刊上。Crutcher博士还将建立一个网站，提供关于宇宙磁场的教育和研究资源。该研究项目将涉及本科生和一名研究生。
