This project aims to solve one of the fundamental problems in astrophysics, how the first stars in the Universe were formed after the Big Bang. Using high-resolution simulations, including magnetic fields and jet/outflow feedback, the mass function of the first stars can be determined. The project will transform our understanding of how the first heavy elements were created in the Universe, providing crucial input for Australian-lead international and national observational surveys, and semi-analytic models of galaxy, star and planet formation, all directly following the formation of the first stars. This project will contribute to three of the six big questions defined in the Decadal Plan for Australian Astronomy 2016-2025, expand knowledge in the physical sciences and drive the next generation of large facilities and Australian frontier technologies.

该项目旨在解决天体物理学中的一个基本问题，即宇宙大爆炸后宇宙中的第一批恒星是如何形成的。通过高分辨率的模拟，包括磁场和喷流/流出反馈，可以确定第一批恒星的质量函数。该项目将改变我们对宇宙中第一批重元素是如何产生的理解，为澳大利亚领导的国际和国家观测调查以及星系、恒星和行星形成的半分析模型提供关键输入，所有这些都直接跟随第一批恒星的形成。该项目将为2016-2025年澳大利亚天文学十年计划中确定的六个大问题中的三个做出贡献，扩展物理科学知识，推动下一代大型设施和澳大利亚前沿技术的发展。
