This project aims to determine the evolutionary scenarios of thermonuclear supernovae through numerical simulations. Supernova explosions create heavy elements, such as iron, that enable life on Earth, and are instrumental in proving that the Universe is expanding at an accelerating rate. For all their importance, the nature of their progenitors is still a mystery, which has implications for many fields of astrophysics. Through building inter-institutional and international collaborations, the project is expected to determine where, when, and how often these explosions occur. Benefits will include development of new technological methods and exploitation of Australian-led survey data from national facilities.

该项目旨在通过数值模拟确定热核超新星的演化情景。超新星爆炸产生重元素，如铁，使地球上的生命，并有助于证明宇宙正在加速膨胀。尽管它们很重要，但它们的祖先的性质仍然是一个谜，这对天体物理学的许多领域都有影响。通过建立机构间和国际合作，该项目预计将确定这些爆炸发生的地点、时间和频率。其好处将包括开发新的技术方法和利用来自国家设施的澳大利亚主导的调查数据。
