Core-collapse supernovae ages and metallicities

Massive stars are the main objects that illuminate HII regions and they evolve quickly to end their lives in core-collapse supernovae (CCSNe). Thus, it is important to...大质量恒星是照亮电离氢区（HII regions）的主要天体，它们演化迅速，并最终以核坍缩超新星（core-collapse supernovae, CCSNe）的形式结束自身生命。因此，对其开展研究具有重要意义……
