SN II in host HII regions

Spectral modelling of typeII supernova atmospheres indicates a clear dependence of metal line strengths on progenitor metallicity. This dependence motivates further work to...对II型超新星（Type II supernova）大气开展的光谱建模研究表明，金属谱线强度与前身星金属丰度（progenitor metallicity）存在显著的依赖关系。这一依赖特性为后续相关研究提供了明确的研究动机……
