“赤方气”:古代超新星的光环?
2005年
发现了三国时代魏国学者孟康为司马迁<史记>中关于景星的记叙所作的一则注解: '有赤方气与青方气相连, 赤方中有两黄星, 青方中一黄星'.在后来唐代人所撰的<晋书>和<隋书>等史籍中,也发现了几乎相同的记载.这种'赤方气'记载所描绘的天象, 与哈勃空间望远镜(HST)拍摄的带有光环结构的超新星1987A 的图像很相似.考虑古代人虽然对一些天象的意义有错误的理解, 但是他们对所看到过天象的描述一般地是客观的, 他们不大可能凭空臆造出'赤方气'这种天象.因此, 推测古代观察者很可能目睹过其遗迹中带有环结构的暴发时非常亮的超新星, 从而留下了'赤方气'的记载.孟康可能是第一个提出'赤方气'说的学者, 而且他大约生活于公元180~250年, 出生时间很接近于公元185年.考虑这两个条件, '赤方气'记载或许与暴发于公元185年的超新星(SN185)有关.这一推测与部分现代研究者测得的SN185可能的遗迹G315.4-2.3的距离参数相符合.如果'赤方气'之说与超新星遗迹中光环结构的关系能够被进一步证实, 这一结果将再次表明, 在超新星暴发一段时间之后显示出环结构应是很普遍的现象.这将是对现代恒星演化理论的一个重要检验.

“Chi-Fang-Qi”: Is it the aureole of an ancient supernova?
2005年
An annotation for the statement about Jing- Xing (Great Star) in the most famous Chinese ancient his- torical book Shi Ji (Historical Records) authored by Sima Qian reads as follows: “There was a red aureole (“Chi-Fang-Qi”) which connected with a deep-color aureole (“Qing-Fang-Qi”). Two yellow stars were in the red aureole, one yellow star was in the deep-color aureole”. The author of the annotation was Meng Kang, an officer as well as a scholar of the Wei State in the Three Kingdoms period. The same records are to be found in two other Chinese historical books compiled by the authors of later ages in Tang Dy- nasty ――Jin History and Sui History. The scene illustrated by the record of “Chi-Fang-Qi” is very similar to the pictures of SN1987A taken by the Hubble Space Telescope. Let it be noted that although the ancient authors were often with se- rious wrong understandings of some astronomical phenom- ena such as supernovae, their depictions about natural phe- nomena they witnessed were mostly objective, and it was unlikely that they fictionally made the record of “Chi-Fang-Qi”. We infer that the ancient observers might have ever watched a very bright supernova with an aureole structure in its remnant and then left such a record. Meng Kang perhaps was the first to give the record about “Chi-Fang-Qi”, and he might have lived in the period from about AD 180 to AD250, very near to AD 185, so, here the supernova the ancient people watched was most likely the one in the year of AD 185. This supposition is consistent with the distance parameter of the most possible remnant of SN185 derived by some modern measurements. If the corre- lation between the record of “Chi-Fang-Qi” and the super- nova remnant can be further proven true, it would be an important verification of the modern theory about stellar evolution.
