论文摘要
IA型超新星（SNE IA）可能是碳 - 氧白猎犬星的热核爆炸，但它们的祖细胞系统仍然难以捉摸。已经提出了一些有关祖细胞系统的理论场景，这些情况已证明与SNE IA的某些观察性质一致。但是，一些计算挑战禁止与观测值进行良好的比较。我们专注于观察到的$ t_0-m_ \ text {ni56} $关系，其中$ t_0 $（$γ$ -rays从弹射器中的逃生时间）与$ m_ \ text {ni56} $（合成的$^{56} $ ni ass）呈正相关。与$ t_0-m_ \ text {ni56} $关系绕过辐射传输计算的需求相比，因为可以直接从弹射器中推断出$ t_0 $的值。我们表明，所有已知的SNE IA模型都无法重现观察到的$ T_0-M_ \ text {ni56} $相关性。
Type Ia supernovae (SNe Ia) are likely the thermonuclear explosions of carbon-oxygen white-dwarf stars, but their progenitor systems remain elusive. A few theoretical scenarios for the progenitor systems have been suggested, which have been shown to agree with some observational properties of SNe Ia. However, several computational challenges prohibit a robust comparison to the observations. We focus on the observed $t_0-M_\text{Ni56}$ relation, where $t_0$ (the $γ$-rays' escape time from the ejecta) is positively correlated with $M_\text{Ni56}$ (the synthesized $^{56}$Ni mass). Comparing to the $t_0-M_\text{Ni56}$ relation bypasses the need for radiation transfer calculations, as the value of $t_0$ can be directly inferred from the ejecta. We show that all known SNe Ia models fail to reproduce the observed $t_0-M_\text{Ni56}$ correlation.
