This project aims to understand how the elements forged in stars flow through space and find their way into new stars and planets, using a combination of high-resolution numerical simulations and novel methods in machine learning. The history of these elements, and how they came to be in planets like ours, is one of the most basic questions remaining in astrophysics. The expected outcome is to provide a model for the history of the elements that can both stand on its own and provide a theoretical basis and a set of statistical tools to interpret the flood of data that will arrive from Australian and international telescopes over the next five years. The project will provide deeper insight into the history of the chemical elements that make up stars and our planet. It will also leverage Australia’s significant investment in observational excellence and hardware and enhance Australia’s leadership in astronomy.

该项目旨在了解恒星中锻造的元素如何通过空间流动并找到进入新恒星和行星的方式，使用高分辨率数值模拟和机器学习中的新方法相结合。这些元素的历史，以及它们是如何出现在像我们这样的行星上的，是天体物理学中最基本的问题之一。预期的结果是为元素的历史提供一个模型，既可以独立存在，又可以提供理论基础和一套统计工具，以解释未来五年内澳大利亚和国际望远镜将提供的大量数据。该项目将提供更深入的了解构成恒星和我们星球的化学元素的历史。它还将利用澳大利亚在观测卓越性和硬件方面的大量投资，并加强澳大利亚在天文学方面的领导地位。
