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5年职业项目的主要研究目标是对太阳能发电机模型提供新的限制，以便更好地了解太阳和太阳能周期动力学。 在项目的过程中，PI将通过完成诸如：（i）测量表面和太阳对流区域的子午线和区域流的任务来完成既定科学目标，以实现既定的科学目标； （ii）在几乎两个太阳周期上量化这些流量的时间变化； （iii）理解和纠正Heliose震源数据集中的系统学，部分通过使用数值模拟。 多样化的研究生和本科生将进行这项研究，最终将：（i）在Heliose杂志学领域培养两名博士学位毕业生； （ii）为十个少数族裔提供了从事有意义的研究经验的机会； （iii）刺激有关Sun和基于高级内容的专业发展培训的相关的6年级学习活动。 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。
