灾变变星可能是古代远东客星的对应物

Cataclysmic variables as possible counterparts of ancient Far Eastern guest stars

Susanne M Hoffmann, Nikolaus Vogt

摘要:

继续我们的努力,选择可能的经典新星候选人之间的远东客星,并确定他们与现代激变变量(CV),我们提出了一个搜索对应的24个有前途的地区的天空中的古代观测公元前204年和公元1690年之间。这些领域已经由我们在以前的文件。根据我们地区CV的物理实体和与望远镜经典新星已知爆发幅度分布相适应的合理震级限制,我们提出了一个总共80个CV和相关目标的目录,这些目标可能导致历史上的目击事件。通过另外讨论案文中更模糊的进一步信息,这一清单可能会减少。在某些情况下,我们提出了一个详细的讨论古代来源的解释,面对他们在该领域最明亮的CV的属性。为了估计这个列表是否具有代表性,我们讨论了CV类型在我们的历史事件对应目录中的分布。与整个天空相比,除了极和中间极外,我们搜索的大多数CV子类型的表面密度显示出相似的值,即。e.强磁性简历,在我们的搜索领域中发现了大量过量。最后,我们展望了未来的研究在这个主题,并在附录中添加了一个完整的图集的天体图的所有24个客星事件,显示搜索区域和CV的位置在其中。

英文摘要:

Continuing our efforts to select possible classical nova candidates among Far Eastern guest stars and to identify them with modern cataclysmic variables (CVs), we present a search for counterparts in 24 promising areas of the sky corresponding to ancient observations between 204 BCE and 1690 CE. These areas have been derived by us in a previous paper. Based on physical entities of the CVs in our areas and reasonable magnitude limits compatible with the distribution of known eruption amplitudes of telescopic classical novae, we present a catalogue of a total of 80 CVs and related targets which could possibly have caused the historical sightings. This list could potentially be reduced by additionally discussing further information more vaguely given in the text. In some cases, we present a detailed discussion of the interpretation of ancient sources confronting them with properties of the brightest CVs in the field. In order to estimate whether this list is representative, we discuss the distribution of CV types in our catalogue of counterparts for the historical events. Compared to the entire sky, the surface density of most CV subtypes in our search fields reveals similar values, except for polars and intermediate polars, i. e. strongly magnetic CVs, for which a significant excess in our search fields was detected. Finally, we give an outlook towards future research in this topic, and add in an Appendix a complete atlas of the celestial maps of all 24 guest star events, displaying the search areas and locations of CVs within them.
