Abundances of red giants in 47 Tuc

47 Tuc is an ideal target to study chemical evolution and globular cluster (GC) formation in massive more metal-rich GCs, as it is the closest massive GC. We present chemical...杜鹃座47（47 Tuc）是研究富金属大质量球状星团（globular cluster, GC）的化学演化与形成机制的理想观测靶标，因其为距离地球最近的大质量球状星团。本研究报道了其化学……
