Metal-poor stars identification method

We developed a metal-poor candidate selection method based on flux-ratios from the BP/RP Gaia spectra, using simulated synthetic spectra. We found a relation between the...我们基于盖亚（Gaia）卫星BP/RP（蓝通带/红通带）光谱的通量比（flux-ratios），结合模拟合成光谱，开发了一种贫金属候选体筛选方法。我们发现了……之间的关联关系。
