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 ##IMG## [http://ej.iop.org/images/2515-5172/4/9/158/rnaasabb9a3ieqn1.gif] {${t}_{0}\mbox{--}{M}_{{\rm{N}}{\rm{\small{I}}}56}$} relation, where t 0 (the γ -rays’ escape time from the ejecta) is positively correlated with ##IMG## [http://ej.iop.org/images/2515-5172/4/9/158/rnaasabb9a3ieqn2.gif] {${M}_{{\rm{N}}{\rm{\small{I}}}56}$} (the synthesized 56 Ni mass).

所有已知的SN Ia模型都无法重现所观察到的t 0 – MNI 56相关性

SNe Ia可能是碳氧白矮星的热核爆炸，但其祖先系统仍然难以捉摸。已经提出了一些关于祖细胞系统的理论方案，这些方案已经显示出与SNe Ia的某些观测特性一致。但是，一些计算难题使我们无法与观察结果进行可靠的比较。我们专注于观察到的## IMG ## [http://ej.iop.org/images/2515-5172/4/9/158/rnaasabb9a3ieqn1.gif] {$ {t} _ {0} \ mbox {- -} {M} _ {{\ rm {N}} {\ rm {\ small {I}}} 56} $}关系，其中t 0（与γ射线从喷出物的逸出时间）正相关## IMG ## [http://ej.iop.org/images/2515-5172/4/9/158/rnaasabb9a3ieqn2.gif] {$ {M} _ {{\ rm {N}} {\ rm { \ small {I}}} 56} $}（合成的56 Ni质量）。与## IMG ## [http：//ej.iop.org/images/2515-5172/4/9/158/rnaasabb9a3ieq ...
