研究IRAS 01005+7910中光谱变化，通过比较不同日期光谱发现Hα和Hβ线轮廓及风成分有显著变化，检测到径向速度变化，将禁线固定位置作为改进系统速度，综合特性表明其为经历过热底燃烧阶段的后AGB星。
AI 中文摘要
不同观测日期获得的光谱比较显示，复杂的Hα和Hβ线轮廓有显著变化，如2025至2026年其发射峰值强度比2013年有系统性增加，且风成分有强烈变化。检测到的径向速度V⊙在-20至-68 km/s之间变化，标准差约8.0 km/s，这可解释为脉动或伴星存在的结果。禁线的固定位置取为改进的系统速度。总体而言，IRAS 01005+7910的一系列特性表明它是一颗经历过热底燃烧阶段的后AGB星。
英文摘要
Comparison of the spectra obtained at different observing dates shows significant variations in the complex H$α$ and H$β$ line profiles, such as a systematic increase in their emission peak strengths in 2025$÷$2026 compared to those observed in 2013 as well as a strong variability in their wind component. A detected variable radial velocity $V_{\odot}$ from $-20$ to $-68$ km/s with a standard deviation of the mean value of K$\sim$8.0 km/s can be interpreted as a result of pulsations or the presence of a companion. The stationary positions of forbidden lines with a mean radial velocity of $V_{\odot}=-51.38\pm0.26$ km/s are taken as an improved systemic velocity. Overall, a set of properties of IRAS 01005+7910 points to its status as a post-AGB star, which has undergone the hot-bottom burning phase.
