Mapping the Dynamics of the Milky Way: The Bar to the Edge of the Disk

ast - 0602221 frinchaboy PeterDr。Frinchaboy获得了美国国家科学基金会天文学和天体物理学博士后奖学金，在威斯康星大学麦迪逊分校开展研究和教育项目。虽然银河系通常为详细研究盘状星系的化学动力学提供了一个独特的实验室，但银河系的许多关键区域对了解盘状星系的演化至关重要，但研究仍然很少：例如，中央棒和外盘的结构和动力学。Frinchaboy博士将(1)测量恒星的运动学和沿银河条形轨道的流运动，以确定其范围和条形轨道的性质；(2)测量银河系条形恒星的金属丰度，以探测条形的演化；(3)确定银河系外盘的起源和化学历史。Frinchaboy博士还将开发技术，将研究整合到非传统小型学院的课程中，并为未来教授教授非传统学生做好准备。特别是，Frinchaboy博士将开发以探究为基础的实验室，该实验室将利用公开可用的天文数据以及学生通过少量威斯康星大学望远镜时间获得的数据。Frinchaboy博士将开发两个为期4-6周的研究项目，教授恒星演化和宇宙距离尺度的基础知识；这些项目将在威斯康星大学白水分校和麦迪逊地区技术学院的课堂上实施。Frinchaboy博士将使用威斯康星大学麦迪逊分校的DELTA综合研究、教学和学习项目开发的方法，通过测试学生的理解和解决问题的能力来评估这些新的实践、探究式学习技术的有效性。Frinchaboy博士还将为博士后和研究生提供一个研讨会，为未来的小型大学教授做好准备，以应对非传统学生带入课堂的不同背景和经历。

AST-0602221Frinchaboy, PeterDr. Frinchaboy is awarded an NSF Astronomy and Astrophysics Postdoctoral Fellowship to carry out a program of research and education at the University of Wisconsin-Madison. While the Milky Way generally provides a unique laboratory for detailed studied of the chemodynamics of disk galaxies, many key areas of the Milky Way that are essential to understanding the evolution of disk galaxies still remain poorly studied: e.g., the structure and dynamics of both the central bar and the outer disk. Dr. Frinchaboy will (1) measure stellar kinematics and streaming motions along the Galactic bar to determine its extent and the nature of bar orbits, (2) measure metallicities of Galactic bar stars to probe bar evolution, and (3) determine the origin and chemical history of the outer Milky Way disk. Dr. Frinchaboy will also develop techniques to integrate research into courses in non-traditional, small colleges and to prepare future professors for teaching non-traditional students. In particular, Dr. Frinchaboy will develop inquiry-based labs that will utilize publicly available astronomical data as well as data that students obtain themselves with a small amount of University of Wisconsin telescope time. Dr. Frinchaboy will develop two 4-6 week long research-based projects to teach the fundamentals of stellar evolution and the cosmological distance scale; these projects will be implemented in the classrooms of University of Wisconsin-Whitewater and at the Madison Area Technical College. Using methods developed by the DELTA program of Integrating Research, Teaching and Learning at the University of Wisconsin-Madison, Dr. Frinchaboy will assess the effectiveness of these new hands-on, inquiry-based learning techniques by testing the comprehension and problem-solving skills of the students. Dr. Frinchaboy will also provide a workshop to postdocs and graduate students to prepare future small college professors for the different backgrounds and experiences that non-traditional students bring into the classroom.
