9311451 Jeffries This project will use sub-millimeter solar observations, including occultation curves of the extreme solar limb obtained during total eclipses in 1981, 1988, and 1991, to model the solar chromosphere taking account of inhomogeneous structure and departures from hydrostatic equilibrium. The eclipse observations cover the wavelength range from 30 to 1300 microns and were obtained on the Kuiper Airborne Observatory (1981, 1988) and at the James Clark Maxwell Telescope on July 11, 1991. The analysis will be carried out using theoretical techniques which we have developed over the past few years, and which will allow the project to apply the power of LTE diagnostics (offered by the continuum at these wavelengths) to highly structured, inhomogeneous chromospheric models. The objective is to obtain the simplest multicomponent model which can satisfy the eclipse data and the center-to-limb measurements at these sub-millimeter wavelengths, while remaining consistent with the observed central disk intensities at other wavelengths and with the morphology shown in images of the different layers of the solar atmosphere. ***

9311451 Jeffries 该项目将使用亚毫米太阳观测，包括 1981 年、1988 年和 1991 年日全食期间获得的极端太阳边缘的掩星曲线，以模拟太阳色球层，同时考虑到不均匀结构和流体静力平衡的偏离。 日食观测覆盖了 30 至 1300 微米的波长范围，是在柯伊伯机载天文台（1981 年、1988 年）和詹姆斯·克拉克·麦克斯韦望远镜于 1991 年 7 月 11 日获得的。分析将使用我们在过去几年中开发的理论技术进行，这将使该项目能够将 LTE 诊断的力量（由这些波长的连续谱提供）应用于 高度结构化、不均匀的色球模型。 目标是获得最简单的多分量模型，该模型可以满足这些亚毫米波长下的日食数据和中心到边缘测量，同时与其他波长下观测到的中心盘强度以及太阳大气不同层图像中显示的形态保持一致。 ***
