论文摘要
可靠的确定热发射线星的基本物理特性和可变性模式对于理解现象，最终是恒星的进化阶段很重要。这项研究致力于最引人注目的恒星之一，V1294 AQL = HD 184279。我们收集并分析了光谱和光度观测值，涵盖时间间隔约为25000 d（68年）。我们提供证据表明该物体是单线192.9 D光谱二进制的，并且估计次级可能是一个热的物体，质量约为1.1-1.2太阳能块。我们发现并记录了非常复杂的轨道和长期光谱，光和颜色变化，这些变化必须由几种不同的可变性模式的组合产生。计划对它们进行建模尝试进行后续研究。我们将V1294 AQL的时间行为置于上下文中，并以其他系统研究的其他研究为星星，并讨论有关BE现象本质的当前思想。
A reliable determination of the basic physical properties and variability patterns of hot emission-line stars is important for understanding the Be phenomenon and ultimately, the evolutionary stage of Be stars. This study is devoted to one of the most remarkable Be stars, V1294 Aql = HD 184279. We collected and analysed spectroscopic and photometric observations covering a time interval of about 25000 d (68 yr). We present evidence that the object is a single-line 192.9 d spectroscopic binary and estimate that the secondary probably is a hot compact object with a mass of about 1.1-1.2 solar masses. We found and documented very complicated orbital and long-term spectral, light, and colour variations, which must arise from a combination of several distinct variability patterns. Attempts at modelling them are planned for a follow-up study. We place the time behaviour of V1294 Aql into context with variations known for some other systematically studied Be stars and discuss the current ideas about the nature of the Be phenomenon.
