Chromospheric Modelling Based on Submillimeter Eclispe Observations

9311451杰弗里斯这个项目将使用亚毫米太阳观测，包括在1981年、1988年和1991年日全食期间获得的极端日冕的掩星曲线，以模拟太阳色球，考虑到不均匀的结构和偏离流体静力平衡的情况。这次日食观测覆盖了30到1300微米的波长范围，并于1991年7月11日在柯伊伯空中天文台(1981,1988)和詹姆斯·克拉克·麦克斯韦望远镜上获得。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诊断的能力(由这些波长的连续谱提供)应用到高度结构化的非均匀色球模型中。其目的是获得最简单的多组分模型，该模型可以满足这些亚毫米波长的日食数据和中心到边缘的测量，同时保持与在其他波长的观测到的中心盘强度以及太阳大气不同层的图像所显示的形态一致。***

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. ***
