Alfven Waves in the Solar Atmosphere

首席研究员（PI）将研究阿尔文波在加热太阳色球层和日冕以及激发这些层中的大气振荡方面所起的作用。为此，他将追求的产生，传播和阿尔文波在太阳色球和日冕耗散的全面研究。PI将使用数值代码模拟太阳大气中的线性和非线性Alfvén波和Alfvén类波（特别是太阳磁通量管内的横波和扭转波），并具有多维磁场几何形状。PI将根据现有的观测数据对这些结果进行检验，并将为解释先进技术太阳望远镜（ATST）的未来观测结果和欧洲格里戈尔望远镜的当前观测结果奠定理论基础。 通过这项调查，PI希望确定太阳大气的主要能源和负责创建日光层的基本物理过程。这些研究成果将通过PI的项目网站、期刊出版物和主要科学会议的特别会议广泛传播。PI将通过直接让本科生和博士研究生参与本项目，并将本研究纳入天体物理学和太阳物理学现有的研究生和本科生课程，加强研究生和本科生教育。PI将为位于德克萨斯大学阿灵顿校园内的新天文馆创建演示，展示这项工作的科学成果，每年访问校园天文馆的数千名K-12学生和大型公众团体。此外，PI的所有计算机代码、演示和预印本都将在项目网站上提供，供其他感兴趣的研究人员和教育工作者下载。

The Principal Investigator (PI) will investigate the role played by Alfvén waves in heating the solar chromosphere and corona, as well as in excitation of atmospheric oscillations in these layers. To this end, he will pursue a comprehensive study of the generation, propagation, and dissipation of Alfvén waves in the solar chromosphere and corona. The PI will use numerical codes to simulate linear and nonlinear Alfvén and Alfvén-like waves in the solar atmosphere (specifically, transverse and torsional waves within solar magnetic flux tubes) with multidimensional magnetic field geometries. The PI will test these results against available observational data and will develop a theoretical basis for interpretation of the future observations expected from the Advanced Technology Solar Telescope (ATST) and the current observations from the European GREGOR telescope. Through this investigation, the PI hopes to identify the principal energy sources of the solar atmosphere and the basic physical processes responsible for creating the heliosphere. These research results will be widely disseminated through the PI's project website, journal publications, and special sessions at major science conferences. The PI will enhance graduate and undergraduate education by directly involving undergraduate and PhD graduate students in this project, and by incorporating this research into existing graduate and undergraduate courses in astrophysics and solar physics. The PI will create demonstrations featuring science results from this effort for a new planetarium located on the campus of the University of Texas at Arlington, reaching out to thousands of K-12 students and large public groups who visit the campus planetarium each year. In addition, all of the PI's computer codes, demonstrations, and preprints will be made available at the project website for other interested researchers and educators to download.
