Submillimeter Observations of the Sun at the Caltech Submillimeter Observatory and the James Clerk Maxwell Telescope

这笔拨款将允许使用15米詹姆斯·克拉克·麦克斯韦望远镜（JCMT）在亚毫米波段对太阳进行一系列观测，该望远镜最近在莫纳克亚山投入使用。这台新望远镜将使观测太阳的角度分辨率远高于过去的望远镜。这里提出的计划将分为两部分：(1)在一定波长范围内详细观测太阳强度振荡；(2)对太阳光度输出的观测；这将导致太阳表面温度分布的一个更好的模型。这些主题与色球结构和动力学密切相关，因此与太阳地球研究密切相关。资助这项研究计划的部分动机是新的强大设备提供了令人兴奋的机会，可以探索以前由于技术限制而无法进入的领域。但更重要的是，亚毫米观测提供了独特的诊断优势，即光谱线的形成简单且易于理解。这个程序对于阐明太阳大气的结构和动力学具有根本的重要性。一个更广泛的目的是打开莫纳克亚山的亚毫米望远镜，使其成为亚毫米和毫米太阳研究的无限可能

This grant will permit a series of observations of the Sun at submillimeter wavelengths using the 15 m James Clerk Maxwell Telescope (JCMT), which has recently become operational on Mauna Kea. This new telescope will allow observations of the Sun with an angular resolution far better than that attainable in the past. The program proposed here will have two parts: (1) detailed observations of solar intensity oscillations over a range of wavelengths; (2) observations of the photometric output of the sun; this will lead to a better model of the temperature distribution on the solar surface. These topics are highly relevant to chromospheric structure and dynamics and hence solar terrestrial research. Part of the motivation in funding this research program is the exciting opportunity provided by new powerful facilities to explore an area previously inaccessible because of technical limitations. But more than this, submillimeter observations offer the unique diagnostic advantage that the spectral line formation is simple and well understood. The program is of fundamental importance for clarifying the structure and dynamics of the solar atmosphere. A broader purpose is to open the submillimeter telescopes at Mauna Kea to the unlimited possibilities of submillimeter and millimeter solar research.//
