This project aims to address the long-standing question in astrophysics of how elements are produced by stars and recycled through galaxies. While it is established that stars are key producers of many of the elements in the universe, the processes that govern their elemental production remains unclear. This project will use an innovative interplay of pioneering observations of dying stars in our galaxy and its neighbours, with state-of-the-art stellar models. The expected outcomes should provide a framework for understanding the chemical make-up of galaxies and the evolution of the Universe. This project will further elevate Australia's global standing in the field of astronomy and maximise returns on Australia's national investment in astronomy infrastructure.

该项目旨在解决天体物理学中长期存在的问题，即元素如何由恒星产生并通过星系循环利用。虽然已确定恒星是宇宙中许多元素的主要生产者，但控制其元素生产的过程仍不清楚。该项目将利用对我们银河系及其邻近星系中垂死恒星的开创性观测与最先进的恒星模型的创新相互作用。预期的结果应该为理解星系的化学组成和宇宙的演化提供一个框架。该项目将进一步提升澳大利亚在天文学领域的全球地位，并最大限度地提高澳大利亚国家天文学基础设施投资的回报。
