远东客星的对应物：新星，超新星，还是别的什么？
Counterparts of Far Eastern Guest Stars: Novae, supernovae, or something else?
摘要：
瞬态的历史观测对于研究其长期演变至关重要。本文是一系列论文的一部分，我们在这些论文中开发了用于分析瞬态事件的古代数据及其在现代科学中的可用性的方法。其他作者在这方面的研究主要集中在寻找历史上的超新星，而我们早期的工作主要集中在作为经典新星的灾变双星上。在这项研究中，我们考虑行星状星云，共生星，超新星遗迹和恒星在我们的测试样本的搜索领域。我们提出的可能性，这些对象类型的视觉爆发，给他们的分布在全球范围内的概述，并讨论在我们的搜索领域的对象单独。为了总结我们的结果，我们提供了一个表格，在我们的测试样本中最有可能识别的历史目击事件，并概述了我们的方法，以便在未来的工作中将其应用于进一步的历史记录。我们的研究结果的亮点包括重新解释两个独立的目击事件作为一个超新星观测从公元667年5月到668年6月，其残余可能是SNR G160.9+02.6。我们还建议经常性的新星U Sco作为891年在天蝎座和蛇夫座之间观察到的外观的候选者，这可能指向喷发幅度的长期变化。此外，我们发现，1431年的“闪亮的明亮”观测可以与共生双星KT Eri联系起来，后者在2009年爆发为肉眼可见的经典新星。
英文摘要：
Historical observations of transients are crucial for studies of their long-term evolution. This paper forms part of a series of papers in which we develop methods for the analysis of ancient data of transient events and their usability in modern science. Prior research on this subject by other authors has focused on looking for historical supernovae and our earlier work focused on cataclysmic binaries as classical novae. In this study we consider planetary nebulae, symbiotic stars, supernova remnants and pulsars in the search fields of our test sample. We present the possibilities for these object types to flare up visually, give a global overview on their distribution and discuss the objects in our search fields individually. To summarise our results, we provide a table of the most likely identifications of the historical sightings in our test sample and outline our method in order to apply it to further historical records in future works. Highlights of our results include a re-interpretation of two separate sightings as one supernova observation from May 667 to June 668 CE, the remnant of which could possibly be SNR G160.9+02.6. We also suggest the recurrent nova U Sco as a candidate for the appearance observed between Scorpius and Ophiuchus in 891, which could point towards a long-term variability of eruption amplitudes. In addition, we find that the `shiny bright' sighting in 1431 can be linked to the symbiotic binary KT Eri, which erupted as a naked eye classical nova in 2009.
