论文摘要
我分析了Su〜uma-type型矮人Nova V844 HE的2020年Superoutburst的传输系外行星调查卫星（TESS）观察结果。该对象显示“教科书”超烟阶段A，B和C通过现代卫星观测确认。最终的数字可用于说明在创意共享（CC-BY-NC）许可下超级峰阶段的概念。在超级雨的增长阶段，该时期最初接近，但比轨道时期稍长。观察者应注意这种现象的存在，不要将现象与WZ SGE恒星中的早期超级烟雾混淆。在超出爆炸后，在同一时期内检测到超烟，并未检测到轨道信号。在苏福特爆炸后阶段记录了〜0.5 d的小摇摆，它们可能与Su Uma Star V585 Lyly的开普勒数据中记录的现象相同。
I analyzed Transiting Exoplanet Survey Satellite (TESS) observations of the 2020 superoutburst of the SU~UMa-type dwarf nova V844 Her. This object showed "textbook" superhump stages A, B and C confirmed by modern satellite observations. The resultant figure can be used for an illustration of the concept of superhump stages under the Creative Commons (CC-BY-NC) licence. During the growing phase of superhumps, the period was initially close to, but slightly longer than the orbital period. Observers should pay attention to the presence of such a phenomenon not to confuse the phenomenon with early superhumps seen in WZ Sge stars. After the superoutburst, superhumps were detected for additional 18 d with the same period and no orbital signal was detected. Small wiggles with a period of ~0.5 d were recorded in the post-superoutburst phase and they may be the same phenomenon recorded in the Kepler data of the SU UMa star V585 Lyr.
