Abundances of microlensed stars in the Bulge

We perform a detailed elemental abundance analysis of dwarf stars in the Galactic bulge, based on high-resolution spectra that were obtained while the stars were optically...我们针对银河系核球（Galactic bulge）中的矮星开展了详细的元素丰度分析，该分析依托于恒星在光学观测期间获取的高分辨率光谱（high-resolution spectra）……
