Revealing the history of the Milky Way Galaxy through precision stellar spectroscopy

银河系是如何形成的？这个基本问题的答案在于恒星的化学成分。澳大利亚和国际社会对最先进的设施和调查进行了巨额投资，将产生100万颗星星样本，用于化学分析。为了从这些巡天中充分收集信息，需要尽可能高精度地测量恒星的化学成分。该项目旨在利用最近开创的分析技术，将恒星化学丰度测量领域的精确度提高到前所未有的2%（提高五倍），以绘制银河系在宇宙时间内的演变图。

How did the Milky Way Galaxy form? The answer to this fundamental question lies in the chemical compositions of stars. Enormous investments by the Australian and international community into state-of-the-art facilities and surveys will yield a 1 million star sample for chemical analysis. To fully harvest the information from those surveys requires stellar chemical composition measurements of the highest possible precision. This project aims to use recently pioneered analysis techniques that have led the field of chemical abundance measurements in stars to the unprecedented precision level of 2 per cent (a five-fold improvement) to chart the evolution of our Galaxy over cosmic time.
