项目摘要

The proposers will investigate Alfven waves and magnetic reconnection as primary sources for the heating and acceleration of the solar wind. This research team will analyze new spectroscopic data from the "Extreme ultraviolet Imaging Spectrometer" onboard the Hinode spacecraft in order to resolve the current debate as to whether Alfven waves carry sufficient energy to heat and accelerate the solar wind. The proposers note that these results will provide much needed empirical data to constrain the competing wave-driven and turbulence-driven models of the solar wind, and ultimately help to determine the true solar wind acceleration mechanism.By providing hands-on research experiences for individual teachers each summer at Columbia University's "Summer Research Program for Science Teachers," this team will help improve the commitment and scientific understanding of middle and high school science teachers from the New York City metropolitan area. This activity will have far reaching benefits, since analysis of Columbia's 21-year-old outreach program shows that the teachers who have participated go on to teach about 1,000 students each over the next ten years and also see a 10% increase in the pass rate of their students on the New York State Regents science exam. The proposers will also visit middle and high school science classes to explain their research and answer questions directly from students. Given the fact that New York City has a diverse student population with a high percentage of underrepresented groups and minorities, these education and outreach efforts constitute a high impact program.

提议者将研究Alfven波和磁重新连接，作为太阳风加热和加速的主要来源。该研究团队将分析Hinode航天器上的“极端紫外线成像光谱仪”的新光谱数据，以解决有关Alfven Waves是否具有足够能量以加热和加速太阳风的当前辩论。建议者指出，这些结果将提供急需的经验数据，以限制太阳风的竞争性波动驱动和湍流驱动的模型，并最终有助于确定真正的太阳能风加速度机制。每年夏天，哥伦比亚大学的“科学教师夏季研究计划”的教师将有助于提高对纽约市大都会地区中学和高中科学教师的承诺和科学理解。这项活动将有很大的收益，因为对哥伦比亚21岁的外展计划的分析表明，参加的教师在接下来的十年中会教授约1,000名学生，而且通过率提高了10％他们的学生参加了纽约州摄政科学考试。提议者还将访问中学和高中科学课，以解释他们的研究并直接回答学生的问题。鉴于纽约市拥有多样化的学生人口，而人数不足的群体和少数群体比例很高，因此这些教育和外展工作构成了一项高影响力计划。
