摘要:

我们目前的热辐射和宽带光变曲线和光谱的一套核心坍缩超新星模型爆炸自洽球对称内的PUSH框架。我们分析了这些光变曲线的广泛趋势,并根据形态对其进行分类。我们发现,这些形态类别简单地涉及到祖半径和质量的氢信封。我们提出了一个概念验证敏感变量分析,表明在给定的类别内的光变曲线的属性的一个重要的决定因素是$^{56}$镍质量。我们跟踪从光球到星云阶段的光谱。这些光谱显示在短波长和多普勒频移的Fe II和Ti II吸收线的特征铁线覆盖。为了使这种分析,我们开发了一个第一的管道从一个大规模的祖模型,通过自洽爆炸球对称,电磁同行。这为更详细地分析这些观测量的集体性质打开了大门。我们在go.ncsu.edu/astrodata上提供了一个机器可读的光变曲线和光谱数据库。

英文摘要:

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.
