我们模拟了冲击波传播的范围广泛的核心塌陷presupernovae：从紧凑的WR星爆炸的SNe Ib/C通过非常扩展的信封的窄线SNe IIn。我们发现，辐射冲击的相同物理现象可以在SNe Ib/c中产生仅持续1秒的X射线辐射爆发（光子能量为1 keV），以及在SNe IIn中产生持续数月的非常高的可见光通量。
We simulate shock propagation in a wide range of core-collapsing presupernovae: from compact WR stars exploding as SNe Ib/c through very extended envelopes of the narrow-line SNe IIn. We find that the same physical phenomenon of radiating shocks can produce outbursts of X-ray radiation (with photon energy1 keV) lasting only a second in SNe Ib/c, as well as a very high flux of visual light, lasting for months, in SNe IIn.
