CAREER: New Constraints on the Solar Dynamo Using Helioseismology

这个为期5年的CAREER项目的主要研究目标是为太阳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。 在项目实施过程中，主要研究员将把研究重点放在通过完成以下任务实现既定的科学目标上：（i）测量表面和太阳对流区的纬向和纬向气流随深度和纬度的变化;（ii）量化这些气流在近两个太阳活动周期内的时间变化;（iii）测量太阳对流区的温度和湿度。以及（iii）部分地通过使用数值模拟来理解和校正日震数据集中的系统学。 一个多样化的研究生和本科生群体将开展这项研究，这将最终：（一）产生两个博士毕业生在日震学;（二）提供十个少数民族本科生的机会，从事有意义的研究经验;和，（三）刺激相关的六年级学习活动关于太阳和高层次的内容为基础的专业发展培训的K-12教师。 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。

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.
