Metallicity measurements of ~500 stars across 13 UFDs

We present uniformly measured stellar metallicities of 463 stars in 13 Milky Way (MW) ultra-faint dwarf galaxies (UFDs; M_V_=-7.1 to -0.8) using narrowband CaHK (F395N) imaging...本研究利用窄带CaHK（F395N）成像技术，对银河系（Milky Way，MW）13个超暗矮星系（ultra-faint dwarf galaxies，UFDs；V波段绝对星等M_V介于-7.1至-0.8）内的463颗恒星，报道了经统一测量得到的恒星金属丰度。
