基于Gaia DR3 BP/RP无缝光谱合成测光的金属丰度星表
Bowen Huang ; Haibo Yuan
该星表包含基于全部Gaia DR3 BP/RP 无缝光谱(共计219,197,643条光谱)生成的BP、RP和G波段合成测光星等,以及基于合成测光测量的金属丰度。 经过多种测试,不论矮星还是巨星,其典型金属丰度精度当[Fe/H] = 0且亮度最暗到G ~16时为0.05–0.1 dex。当[Fe/H] = -2.0时,精度下降至0.15–0.25 dex,在[Fe/H]范围为-4.0至-3.0时,精度进一步下降至0.4–0.5 dex。 由于部分源存在超出模型参数范围、观测质量较差或消光估计不准确的情况,因此这些源的结果可能不可靠。为此,我们提供了若干标签用以判断结果的可靠性。此外,为了方便使用该星表,我们还提供了一系列基于Gaia DR3的测光信息。具体细节请参考我们的论文(Huang et al. 2025)。
