AST-9806188 Zita Research quality astronomy observations by students and staff at Evergreen State College will be carried out at the University of Washington at Seattle's (UW) Manastash Ridge Observatory (MRO). The first step is to train observers to use the telescope and work at MRO. Observations, analysis of data, and upgrading the telescope will be carried out. The MRO telescope will be upgraded so that observations may by made remotely. The facility will be with shared with other observers from other institutions. Undergraduate students will take active part in the research, and they will be the first generation of students doing astronomy research at the Evergreen State College. The ongoing theoretical work strongly motivates the establishment of an Evergreen astronomy research program. The testing of new stellar dynamics models will guide the longer-term directions of the future observational work. At the present, astronomy observations at MRO will provide needed experience in observational research, and will facilitate improved communication with other observational astronomers, whose data presently relate to the theory. These activities will lay the groundwork for future theoretical and observational research. A mechanism for the previously unexplained sound waves in magnetic, rapidly oscillating peculiar A stars is being examined. The model extends the basic theory of force-free plasmas and describes how oscillations about a minimum in magnetic energy can drive magnetosonic modes. which appear as sound waves in the stars. The energy, wavelength, and frequency for the theoretical test case is consistent with observations. The model can be tested further by making more detailed calculations and observations. It is planned to learn enough observational astronomy to design a future research program to help test the model. This is a key goal of the future activities. The University of Washington will be involved in the training of Evergreen faculty and students to use the Manastash Ridge Observatory telescope. The telescope will be upgraded so that it can be operated remotely. Students will work at the observatory in the summer and be involved in theoretical research with Evergreen faculty. Students will be able to participate in remote observations at MRO throughout the academic year. They will use software such as that developed by the University of California -Berkeley's Hands-On Universe project and UW's IRAF astronomical data processing system. The activities will build on new working relationships with local colleagues; enhance Evergreen students' education as well as research; and enable staff and students to share remote astronomy observations with teachers and students throughout Washington state. ***

AST-9806188 Zita 万年青州立学院的学生和工作人员将在西雅图的华盛顿大学（UW）马纳斯塔什岭天文台（MRO）进行研究质量天文观测。 第一步是培训观测者使用望远镜并在MRO工作。 将进行观测、数据分析和望远镜升级。将对MRO望远镜进行升级，以便可以进行远程观测。 该设施将与其他机构的其他观察员共用。 本科生将积极参与研究，他们将是在万年青州立学院做天文学研究的第一代学生。 正在进行的理论工作有力地推动了万年青天文学研究计划的建立。 新的恒星动力学模型的测试将指导未来观测工作的长期方向。 目前，MRO的天文观测将提供观测研究所需的经验，并将促进与其他观测天文学家的交流，他们的数据目前与理论有关。 这些活动将为今后的理论和观测研究奠定基础。 一种以前无法解释的声波在磁性，快速振荡的特殊A星的机制正在研究中。 该模型扩展了无力等离子体的基本理论，并描述了如何振荡的最小磁能可以驱动磁声模式。在恒星中表现为声波。 理论测试用例的能量、波长和频率与观测结果一致。 可以通过更详细的计算和观察来进一步测试该模型。 计划学习足够的观测天文学，以设计未来的研究计划，以帮助测试模型。 这是今后活动的一个关键目标。 华盛顿大学将参与培训万年青大学的教职员工和学生使用马纳斯塔什岭天文台望远镜。 该望远镜将升级，以便可以远程操作。 学生们将在夏天在天文台工作，并与万年青教师一起参与理论研究。 学生将能够在整个学年在MRO参与远程观测。 他们将使用诸如加州大学伯克利分校的Hands-On Universe项目和华盛顿大学IRAF天文数据处理系统开发的软件。 这些活动将建立与当地同事的新的工作关系;加强万年青学生的教育和研究;并使工作人员和学生能够与整个华盛顿州的教师和学生分享远程天文观测。 ***
