The main research objective of this 5-year CAREER project is to provide new constraints on solar dynamo models, so that a better understanding of the Sun and solar-cycle dynamics becomes possible. Over the course of the project, the PI will focus his research on achieving the stated science objective by completing tasks such as: (i) measuring the meridional and zonal flows at the surface and in the solar convection zone as functions of depth and latitude; (ii) quantifying the time variations of these flows over almost two solar cycles; and, (iii) understanding and correcting the systematics in helioseismic data sets, in part by using numerical simulations. A diverse cohort of graduate and undergraduate students will carry out this research, which will ultimately: (i) produce two PhD graduates in helioseismology; (ii) provide ten minority undergraduates the opportunity to engage in meaningful research experiences; and, (iii) stimulate relevant 6th-grade learning activities about the Sun and high-level content-based professional development training for K-12 instructors. The research and EPO agenda of this project supports the Strategic Goals of the AGS Division in discovery, learning, diversity, and interdisciplinary research.

这个为期 5 年的 CAREER 项目的主要研究目标是为太阳能发电机模型提供新的约束，以便更好地了解太阳和太阳周期动力学。 在该项目的过程中，首席研究员将通过完成以下任务来重点研究实现既定的科学目标：（i）测量地表和太阳对流区的经向和纬向流作为深度和纬度的函数； (ii) 量化这些流量在近两个太阳周期内的时间变化； (iii) 部分通过数值模拟来理解和纠正日震数据集中的系统学。 不同群体的研究生和本科生将开展这项研究，最终将：（i）培养两名日震学博士毕业生； (ii) 为十名少数民族本科生提供参与有意义的研究经历的机会； (iii) 促进六年级有关太阳的相关学习活动以及针对 K-12 教师的高水平内容专业发展培训。 该项目的研究和 EPO 议程支持 AGS 部门在发现、学习、多样性和跨学科研究方面的战略目标。
