This project aims to explain the origin of stars with a chemical composition that is so peculiar that they cannot be explained by any theory of how stars evolve or how elements are created. Their very existence represents fundamental problems in astrophysics. This project proposes a novel method to distinguish peculiarity of up to 20 million stars, mostly observed from Australia. Expected outcomes include new theories to explain two of the most puzzling kinds of peculiar stars, discoveries of new kinds of anomalous stars, and discoveries of ancient or metal-free stars that should not exist. The project is expected to generate social benefit, as well as long-term economic benefits by inspiring and training the next generation of data analysts, programmers, engineers, teachers, and scientists. It may also generate economic benefits from a generalised method for outlier detection in high-dimensional datasets.

这个项目旨在用一种特殊的化学成分来解释恒星的起源，这种化学成分是任何恒星如何演化或元素如何产生的理论都无法解释的。它们的存在代表了天体物理学的基本问题。这个项目提出了一种新的方法来区分多达2000万颗恒星的特性，这些恒星大多是在澳大利亚观测到的。预期的结果包括解释两种最令人费解的奇特恒星的新理论，发现新的异常恒星，以及发现不应该存在的古老或无金属恒星。该项目有望通过激励和培训下一代数据分析师、程序员、工程师、教师和科学家，产生社会效益和长期经济效益。它还可以从高维数据集的异常值检测的广义方法中产生经济效益。
