论文摘要

我们为一组核心折叠超新星模型提供了侧侧光度和宽带光曲线和光谱,在推动框架内以球形对称性爆炸。我们分析了这些光曲线中的广泛趋势,并根据形态对它们进行分类。我们发现这些形态类别仅与祖细胞半径和氢化膜的质量有关。我们提出了概念验证敏感 - 可变量分析,表明给定类别中光曲线属性的重要决定因素是$^{56} $ ni质量。我们遵循从光球到星云相的光谱。这些光谱在短波长和多普勒偏移的Fe II和Ti II吸收线上显示出特征性的铁线覆盖。为了实现此分析,我们开发了从大型祖细胞模型,通过球形对称性的自洽爆炸到电磁对应物的第一管道。这为这些可观察到的集体特性进行了更详细的分析打开了大门。我们在go.ncsu.edu/astrodata上提供了一个可读的光曲线和光谱的机器数据库。

We present bolometric and broadband light curves and spectra for a suite of core-collapse supernova models exploded self-consistently in spherical symmetry within the PUSH framework. We analyze broad trends in these light curves and categorize them based on morphology. We find these morphological categories relate simply to the progenitor radius and the mass of the hydrogen envelope. We present a proof-of-concept sensitive-variable analysis, indicating that an important determining factor in the properties of a light curve within a given category is $^{56}$Ni mass. We follow spectra from the photospheric to the nebular phase. These spectra show characteristic iron-line blanketing at short wavelengths and Doppler-shifted Fe II and Ti II absorption lines. To enable this analysis, we develop a first-of-its-kind pipeline from a massive progenitor model, through a self-consistent explosion in spherical symmetry, to electromagnetic counterparts. This opens the door to more detailed analyses of the collective properties of these observables. We provide a machine readable database of our light curves and spectra online at go.ncsu.edu/astrodata.
