标题： Synthesizing Sun-as-a-star flare spectra from high-resolution solar observations

摘要： 空间分辨的太阳观测和恒星体的天文学样本大小分别是太阳和恒星观测的各自关键优势。 然而，太阳与其他恒星之间的目标亮度差异导致了这两个领域在仪器和方法上的显著不同。 我们生成并分析了从2011年至2024年间由瑞典1米太阳望远镜（SST）获取的19个小型区域视场的光学观测数据中得出的合成全盘光谱。 这些数据用于研究可以从太阳作为恒星的观测中推断出什么以及不能推断出什么关于太阳上的物理过程。 最近发布的数值经验太阳作为恒星积分器（NESSI）代码基于较小视场输入，考虑了中心到边缘的变化和差分旋转，提供了合成全盘积分光谱线发射。 我们使用该代码从SST观测数据中生成伪太阳作为恒星的光谱。 ... 显示英文摘要

摘要： Spatially resolved observations of the Sun and the astronomical sample size of stellar bodies are the respective key strengths of solar and stellar observations. However, the large difference in object brightness between the Sun and other stars has led to distinctly different instrumentation and methodologies between the two fields. We produce and analyze synthetic full-disk spectra derived from 19 small area field-of-view optical observations of solar flares acquired by the Swedish 1-m Solar Telescope (SST) between 2011 and 2024. These are used to investigate what can and cannot be inferred about physical processes on the Sun from Sun-as-a-star observations. The recently released Numerical Empirical Sun-as-a-Star Integrator (NESSI) code provides synthetic full-disk integrated spectral line emission based on smaller field-of-view input, accounting for center-to-limb variations and differential rotation. We use this code to generate pseudo-Sun-as-a-star spectra from the SST observations. ...
