金属贫星数据集

金属贫星数据集是由海德堡大学天文学中心等机构创建，包含10颗金属贫星的基本参数，如有效温度、表面重力、金属丰度等。数据集通过高精度干涉测量和光谱分析获得，旨在为银河系的大规模恒星调查提供验证标准。这些数据对于理解恒星和银河系的结构与演化至关重要，特别是在解决早期宇宙和银河考古学问题中具有特殊重要性。

The Metal-poor Star Dataset was developed by the Center for Astronomy of Heidelberg University and other institutions. It contains fundamental parameters of 10 metal-poor stars, such as effective temperature, surface gravity, metallicity, and other relevant metrics. The dataset was obtained through high-precision interferometry and spectroscopic analysis, and aims to provide validation standards for large-scale Milky Way stellar surveys. This data is crucial for understanding the structure and evolution of stars and the Milky Way, and is of particular importance for resolving questions related to the early universe and galactic archaeology.
