The light curves of Type Ia supernovae (SNe Ia) are powered by the radioactive decay of ^56^Ni to ^56^Co at early times, and the decay of ^56^Co to ^56^Fe from ~60 d after...
Ia型超新星(Type Ia supernovae,简称SNe Ia)的光变曲线(light curves)在爆发早期由镍-56(⁵⁶Ni)衰变为钴-56(⁵⁶Co)的放射性衰变提供能量,而在爆发后约60天起,则由钴-56(⁵⁶Co)衰变为铁-56(⁵⁶Fe)的衰变过程驱动……
