Analytic Resonance Line Profile Diagnostics: Extension to Background Continua, Blends, and Cross-Redistribution

作者：Kenneth G. 9417090 Gayley将继续他的NSF支持的研究共振线形成和轮廓诊断。我们的目标是扩展到更广泛的一类共振配置文件的分析诊断。他不再像之前那样假设一个孤立的二能级原子，而是将重点放在背景连续不透明度、共振线混合和交叉再分布的诊断等更普遍的影响上。这项研究适用于解释冷星星大气的光谱，特别是冷色球的观测，其温度降低线冷却。***

Gayley, Kenneth G. 9417090 Gayley will continue his NSF-supported research on resonance line formation and profile diagnostics. The goal is to extend the analytical diagnostics derived so far to a wider class of resonance profiles. Instead of assuming an isolated two-level atom as he has done so far, he will focus on the more general effects of background continuum opacity, resonance line blending, and the diagnostics of cross-redistribution. This research is applicable to interpreting spectra of cool star atmospheres, in particular observations of cool chromospheres whose temperatures are depressed by line cooling. ***
