AST 0307934PI RhodesThis research combines a recent breakthrough in the analysis of the high-degree solar oscillations with unique observations available from the worldwide Global Oscillation Network Group to advance our knowledge of the structure and dynamics of outermost layers of the solar interior. This research is making improvements in the scientific community's understanding of the structure and dynamics of the solar interior. The group is carrying out tasks which will provide essential information about the sun which could not be obtained without the use of the sun's high-degree pulsations. This research will provide new knowledge of the stratification, thermodynamics, and rotational shear flows in the upper turbulent convective boundary layer and variations of these properties with time.Broader Impacts: The project will have a broad impact in education, in infrastructure support, and in public outreach through the training and support of both a graduate student and an undergraduate student in observational helioseismology. The P.I. has an established track record of training undergraduate and graduate students, post-doctoral fellows, and high school students and teachers in solar physics by having the students and teachers join his research group both on the University of Southern California campus and at the Mount Wilson Observatory. He also presents regular public lectures, and serves on the Steering Committee of the Mellon Minority Undergraduate Fellowship Program and has served as a faculty mentor for both African-American and Hispanic students. Other members of the team from the Stanford Solar Physics Group have a major on-going effort in Public Outreach activities. The results from the research will be summarized on the Stanford MDI Website. The research also facilitates the collaboration of three major universities, the Technical University of Munich, the University of Southern California, and Stanford.

AST 0307934PI Rhodes这项研究结合了最近在高度太阳振荡分析方面的突破，以及全球振荡网络组的独特观测，以提高我们对太阳内部最外层结构和动力学的认识。这项研究正在提高科学界对太阳内部结构和动力学的认识。该小组正在执行的任务将提供有关太阳的基本信息，如果不使用太阳的高度脉动，就无法获得这些信息。这项研究将提供新的知识的分层，热力学和旋转剪切流在上层湍流对流边界层和这些属性随时间的变化。更广泛的影响：该项目将产生广泛的影响，在教育，基础设施的支持，并通过培训和支持的研究生和本科生在观测日震学的公众宣传。私家侦探在太阳物理学方面，他一直致力于培养本科生、研究生、博士后研究员、高中生和教师，让学生和教师加入他在南加州大学校园和威尔逊山天文台的研究小组。他还定期举办公开讲座，并担任梅隆少数民族本科奖学金计划的指导委员会，并担任非裔美国人和西班牙裔学生的教师导师。来自斯坦福大学太阳物理小组的其他成员在公共外展活动方面有着重大的持续努力。研究结果将在斯坦福大学MDI网站上进行总结。该研究还促进了三所主要大学的合作，即慕尼黑技术大学、南加州大学和斯坦福大学。
