摘要:

我们研究了在核塌缩超新星中产生44 Ti和56 Ni的物理条件。在这项初步工作中,我们使用了一系列的后处理网络计算与参数化的膨胀配置文件,这些配置文件代表了在3D超新星模拟中发现的广泛的温度,密度和电子与重子的比例。对影响44 Ti和56 Ni最终产率的临界流动进行了评估。

英文摘要:

We investigate the physical conditions where 44Ti and 56Ni are created in core-collapse supernovae. In this preliminary work we use a series of post-processing network calculations with parametrized expansion profiles that are representative of the wide range of temperatures, densities and electron-to-baryon ratios found in 3D supernova simulations. Critical flows that affect the final yields of 44Ti and 56Ni are assessed.
