HST observations of nearby core-collapse SNe

We age-date the stellar populations associated with 12 historic nearby core-collapse supernovae (CCSNe) and two supernova impostors; from these ages, we infer their initial...我们对与12颗历史上已观测到的邻近核坍缩超新星（CCSNe）以及2颗超新星伪爆发（supernova impostors）相关的恒星族群开展了年龄测定；基于这些年龄数据，我们推导出它们的初始……
