CAREER: New Constraints on the Solar Dynamo Using Helioseismology

这项为期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条件，从而更好地了解太阳和太阳周期动力学。在整个项目过程中，项目负责人的研究重点将放在实现既定的科学目标上，完成以下任务：(i)测量地表和太阳对流区的经向和纬向流动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；(3)理解和修正日震数据集的系统性，部分是通过数值模拟。一群不同的研究生和本科生将进行这项研究，最终将：(i)产生两名日震学博士研究生；（ii）为10名少数族裔本科生提供参与有意义的研究经验的机会；（iii）促进六年级有关太阳的相关学习活动，并为K-12教师提供基于内容的高水平专业发展培训。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。

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.
