Improving Solar Physics Content In Astronomy Courses

9351279帕萨克霍夫该项目通过将1994年11月3日日全食研究的准备、观测和数据记录纳入课程，增加了高年级和新生本科生课程中的太阳物理学内容。该设备包括带有适当滤光片的ccd摄像机和数字化设备以及相关的计算机设备，还将与校园内的白光太阳望远镜和氢阿尔法望远镜一起使用。日食研究是在日冕加热原因研究的框架内进行的，此前有预测称，地表阿尔芬波将导致日冕环中的振荡，周期为1-10 S。这个实验的早期版本已经在两次日食中进行过，在家里和现场都有广泛的学生参与，并在我们的傅立叶分析中发现了在这两个周期中能量过剩的迹象。1991年的日全食现场有一个改进的版本，有更多的学生参与，但多云的天气阻止了观测。在南美洲1994年11月3日的日食期间，有一项补充研究经费用于进行这项实验，将使用增强型ccd摄像机、图像采集器和计算机数字化和记录，而不是现有实验装置中的光纤线束和光电倍增管。学生参与这里要求的设备包括新生研讨会和初级/高级太阳物理研讨会的学生，以及现场参加探险的学生。在接下来的几年里，这些数据和设备将在校园里、在望远镜和课程中仍然有用。***

9351279 Pasachoff This project is increasing the solar-physics content of both upper-class and freshman undergraduate courses by incorporating into the courses preparation for, observation of, and data reduction from solar eclipse studies at the 3 November 1994 total solar eclipse. The equipment, comprising CCD cameras with suitable filters and digitizing and associated computer equipment, is also being incorporated into use with the on- campus solar telescope in white light and in hydrogen-alpha. The eclipse work is in the framework of a study of the cause of coronal heating, following predictions that surface Alfven waves would lead to oscillations in coronal loops with periods of 1-10 s. Earlier versions of this experiment have been carried out at two eclipses, with extensive student participation at home and on site, and found indications of excess power at these periods in our Fourier analysis. There was an improved version on site for the 1991 total solar eclipse, with even more extensive student participation, but cloudy weather prevented observation. There is a complementary research grant to perform this experiment at the 3 November 1994 eclipse in South America, Observations will be made with intensified CCD cameras, frame grabbers, and computer digitizing and recording, instead of the fiber-optics strands and photomultipliers in the existing experimental setup. Student participation with the equipment requested here includes students in the Freshman Seminar and the junior/senior solar-physics seminar as well as students participating in the expedition on site. The data and equipment will remain useful on campus, with the telescopes and in the courses, for years to follow. ***
