The stars that should not exist

这个项目旨在用一种如此特殊的化学成分来解释恒星的起源，以至于任何关于恒星如何进化或元素是如何产生的理论都无法解释它们。它们的存在本身就代表了天体物理学中的基本问题。该项目提出了一种新的方法来区分多达2000万颗恒星的特殊性，这些恒星大多来自澳大利亚。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，新类型反常恒星的发现，以及不应该存在的古老或无金属恒星的发现。该项目预计将通过激励和培训下一代数据分析师、程序员、工程师、教师和科学家来产生社会效益和长期经济效益。它还可以从高维数据集中的离群值检测的通用方法中产生经济效益。

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.
