论文摘要

由于它们是宇宙中许多元素的直接或间接来源的角色,核心崩溃超新星的数值建模始于五十多年前。通过越来越复杂的模型实现了确定爆炸机制的进展,因为物理和维度的增加,随着物理和数值建模有所改善,随着建模者可用的领先计算资源的改善,它变得越来越强大。过去的五到十年见证了在核心崩溃的超新星建模社区中达成共识的出现,这些群体在前四十年中没有存在。对于大多数祖细胞(即缓慢旋转的祖细胞),延迟的冲击机制的功效,其中停滞的超新星冲击波通过中微子在proto -neutron Star中散发出的中微子加热而恢复了,所有核心超级崩溃的核心崩溃组都证明了proto -neutron star的中微子,并证明了跨质量collapse collapse Modeling offerapse colleapse collapse Modeling offerations and ofernoce质量质量。有了这一动力,现在对这些事件的动态有了更深入的了解,前进的道路很明显。尽管取得了很多进展,但仍有许多工作要做,但是目前,我们有充分的理由保持乐观,我们可以正常回答天体物理学中最重要的杰出问题之一:大型明星如何结束他们的生命?

Motivated by their role as the direct or indirect source of many of the elements in the Universe, numerical modeling of core collapse supernovae began more than five decades ago. Progress toward ascertaining the explosion mechanism(s) has been realized through increasingly sophisticated models, as physics and dimensionality have been added, as physics and numerical modeling have improved, and as the leading computational resources available to modelers have become far more capable. The past five to ten years have witnessed the emergence of a consensus across the core collapse supernova modeling community that had not existed in the four decades prior. For the majority of progenitors - i.e., slowly rotating progenitors - the efficacy of the delayed shock mechanism, where the stalled supernova shock wave is revived by neutrino heating by neutrinos emanating from the proto-neutron star, has been demonstrated by all core collapse supernova modeling groups, across progenitor mass and metallicity. With this momentum, and now with a far deeper understanding of the dynamics of these events, the path forward is clear. While much progress has been made, much work remains to be done, but at this time we have every reason to be optimistic we are on track to answer one of the most important outstanding questions in astrophysics: How do massive stars end their lives?
