论文摘要
我们认为II型超级新星(SNE IIP)的U频段变化速率变化的影响是金属性$ Z $的函数。基于这种效果,我们提出了一种新方法,以确定U频带中SN IIP光曲线的光度红移。使用Stella代码,我们已经在不同带的不同频段中构建了模型光曲线,用于不同的红移$ z = 0.0、0.1 $和$ 0.3 $,因为型号的金属性从$ z \ sim \ sim 10^{ - 3} $降低至$ \ sim \ sim 10^{ - 6} $。表明U带中的通量以最低的金属度达到平稳性。我们还考虑了其他参数的影响:Presupernova质量和放射性镍56的质量。
We consider the effect of a change in the rate of flux decline in the U band for type II-P supernovae (SNe IIP) as a function of metallicity $Z$. Based on this effect, we propose a new method to determine the photometric redshift from the SN IIP light curve in the U band. Using the STELLA code, we have constructed model light curves in different bands for different redshifts $z = 0.0, 0.1$, and $0.3$ as the metallicity in the models decreases from $Z \sim 10^{-3}$ to $\sim 10^{-6}$. The flux in the U band is shown to reach a plateau at the lowest metallicities. We consider the influence of other parameters as well: the presupernova mass and the mass of radioactive nickel-56.
