论文摘要
在其观察到450年的周年纪念日,可以用如今用来表征IA型超新星(SNE IA)的术语来解释以Tycho Brahe(SN 1572)命名的超新星。通过组装1572---74中观察结果的记录并评估其不确定性,可以恢复该超新星的光曲线和颜色演变。发现在Sne IA家族中,该事件应该是正常下降率的SN IA。关于SNE IA的颜色演变,最近回收的记录重申了先前的发现,即其正常的SN IA。从X射线光谱法的整个残留物的丰富研究表明,chandrasekhar-质量的白矮星的延迟爆炸爆炸的核燃烧。从SN 1572中对田间恒星的探索提出了暂定的单一堕落爆炸路径。但是,也考虑了双堕落中的起源。 Tycho Brahe的Supernova是天文学家学习的第一批超新星,如今仍然是非常密集的辩论的主题。
At the 450 yr anniversary of its observation,the supernova named after Tycho Brahe, SN 1572, can be explained in the terms used nowadays to characterize Type Ia supernovae (SNe Ia). By assembling the records of the observations made in 1572--74 and evaluating their uncertainties, it is possible to recover the light curve and the color evolution of this supernova. It is found that, within the SNe Ia family, the event should have been a SN Ia with a normal rate of decline. Concerning the color evolution of SNe Ia, the most recently recovered records reaffirm previous findings of its being a normal SN Ia. The abundance studies from X--ray spectroscopy of the whole remnant point to a nuclear burning of the kind of a delayed detonation explosion of a Chandrasekhar--mass white dwarf. A tentative single degenerate path to explosion was suggested from the exploration of the stars in the field in SN 1572. Though, the origin in a double degenerate is being considered as well. Tycho Brahe's supernova, being the first supernova studied by astronomers, is still the subject of very intensive debates nowadays.
