摘要

我们对后AGB恒星V1610 Cyg系统中的AFGL 2688星云的光度和光谱观测结果进行了综述。除了对已发表的结果进行分析外，我们还考虑了2002年至2022年在BTA对该恒星的新光谱观测。对星云叶中气体和尘埃的运动学有了新的理解。已发表的全部数据记录在广泛的波长范围内，使我们能够将AFGL 2688视为经历后AGB阶段的恒星的原型星云。对中心恒星化学成分的变化进行了假设。我们讨论了在光学范围内研究物体的前景。

Bipolar Nebula AFGL 2688 in the System of Post-AGB Star V1610 Cyg

We present a survey of the results of photometric and spectral observations of a nebula AFGL 2688 in the system of post-AGB star V1610 Cyg. Apart from the analysis of the published results, our new spectral observations of the star at the BTA over 2002–2022 are also given consideration. A new understanding of the kinematics of gas and dust in the lobes of the nebula has been obtained. The totality of published data, registered in a wide range of wavelengths, allows us to consider AFGL 2688 as a prototype nebula for the stars undergoing the post-AGB stage. An assumption on the variation of the chemical composition of the central star is made. We discuss the prospects for studying the object in the optical range.
