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

盖利，肯尼斯·G·9417090盖利将继续他的国家科学基金会资助的共振线形成和剖面诊断研究。其目标是将到目前为止派生的分析诊断扩展到更广泛的共振谱类别。他不会像他迄今所做的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、共振线混合和交叉重新分布的诊断等更一般的影响上。这项研究适用于解释冷恒星大气的光谱，特别是对其温度因线冷却而降低的冷色球的观测。***

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. ***
