业余天文学家结合高、低分辨率光谱技术，观测共生双星V1413 Aql的2025年食，测量食甚时刻、计算食历表，分析Hα发射线与白矮星视向速度，确定其光谱连续谱符合晚F型或早G型巨星特征。
AI 中文摘要
我们报告了业余天文学家开展的一项协同观测活动，他们结合高分辨率与低分辨率光谱技术，在共生双星天鹰座V1413（V1413 Aql）可能发生Z And型共生星爆发后不久，对该天体的2025年食进行了观测。我们测量了食甚时刻，计算出更新后的食历表；对光谱进行了绝对流量定标，采用多高斯拟合方法分解并量化了Hα发射线的组分；测量了白矮星的视向速度曲线，确定其半振幅为25.7 km/s，系统视向速度为95.1 km/s；还发现光谱连续谱与晚F型或早G型巨星的光谱连续谱一致。
英文摘要
We report on a coordinated campaign by amateur astronomers using a combination of high and low resolution spectroscopy to observe the 2025 eclipse of the symbiotic binary V1413 Aql shortly after a probable Z And-type symbiotic outburst. We measured the eclipse time of minimum and computed an updated eclipse ephemeris. Our spectra were calibrated in absolute flux and multi-Gaussian fits were used to resolve and quantify components of the Hα emission line. We measured the radial velocity curve of the white dwarf and determined the semi-amplitude as 25.7 km/s and the systemic radial velocity as 95.1 km/s. We found the spectral continuum was consistent with that of a late F or early G type giant star.
