核心坍缩超新星科学现在正在进入一个时代，在这个时代，发动机模型开始进行定性预测，在某些情况下，还可以进行定量预测。尽管支持核心坍缩超新星的对流引擎的证据不断增加，但很难对这种引擎进行定量限制。一些研究已经对对流发动机的残余分布做出了具体的预测，但不同小组的预测结果有所不同。在这里，我们使用超新星引擎的广泛参数化来理解不同研究之间的差异。有了这个更广泛的模型集，我们在爆炸发动机的不确定性的残余质量和基本产量上放置了误差条。我们发现，即使只有三个祖元和一个狭窄的爆炸能量范围，我们也可以产生大范围的残余质量和核合成产率。
Core-collapse supernova science is now entering an era in which engine models are beginning to make both qualitative and, in some cases, quantitative predictions. Although the evidence in support of the convective engine for core-collapse supernova continues to grow, it is difficult to place quantitative constraints on this engine. Some studies have made specific predictions for the remnant distribution from the convective engine, but the results differ between different groups. Here we use a broad parameterization for the supernova engine to understand the differences between distinct studies. With this broader set of models, we place error bars on the remnant mass and basic yields from the uncertainties in the explosive engine. We find that, even with only three progenitors and a narrow range of explosion energies, we can produce a wide range of remnant masses and nucleosynthetic yields.
