Gaia FGK Benchmark Stars v3 (GBSv3)
收藏资源简介:
GBSv3数据集由ESO提供,是第三版的Gaia FGK Benchmark Stars,包含202颗恒星的高分辨率光谱库,其中包含192颗GBSv3恒星、9颗来自前GBS版本的恒星和太阳。这些光谱是从公共档案中收集的,并通过作者自己的观测进行补充。数据集提供了13种化学物种(Fe I, Fe II, Mg I, Si I, Ca I, Ti I, Ti II, Sc II, V I, Cr I, Mn I, Co I, Ni I)的化学丰度。GBSv3数据集旨在为光谱学参考星提供改进的统计和均匀性样本,用于校准光谱学调查和测试恒星大气模型。
The GBSv3 dataset, provided by ESO, is the third edition of the Gaia FGK Benchmark Stars. It hosts a high-resolution spectral library of 202 stars, including 192 GBSv3 stars, 9 stars from previous GBS releases, and the Sun. These spectra were collected from public archives and supplemented with observations conducted by the authors themselves. The dataset provides chemical abundances for 13 chemical species: Fe I, Fe II, Mg I, Si I, Ca I, Ti I, Ti II, Sc II, V I, Cr I, Mn I, Co I, Ni I. The GBSv3 dataset is designed to provide improved, statistically consistent and homogeneous samples of spectroscopic reference stars for calibrating spectroscopic surveys and testing stellar atmospheric models.
