论文摘要
SN 2013F闪存频谱的最新研究表明，SN IIP爆炸能量巨大，远远超出了中微子机制的可能性。 SN 2013F的爆炸能量的问题是利用早期超新星相互作用与密集的壳外壳的效果。从第2.4天的宽\ heii \，4686 \，4686 \，第2.4天的宽度\ heii \分析来推断冷壳之间冷壳的速度。该速度与其他可观察到的速度为我们提供了$ \ sim1.8 \ times10^{51} $ \，ERG的替代能量估计，以获得$ \ sim10 $ \ msun的首选质量。推断的值在中微子驱动的爆炸范围内。
The recent study of SN 2013fs flash spectrum suggests enormous for SN IIP explosion energy, far beyond possibilities of the neutrino mechanism. The issue of the explosion energy of SN 2013fs is revisited making use of effects of the early supernova interaction with the dense circumstellar shell. The velocity of the cold dense shell between reverse and forward shocks is inferred from the analysis of the broad \heii\,4686\,Å on day 2.4. This velocity alongside with other observables provide us with an alternative energy estimate of $\sim1.8\times10^{51}$\,erg for the preferred mass of $\sim10$\msun. The inferred value is within the range of the neutrino driven explosion.
