通过研究具有r平方反比密度分布的介质中的自相似爆炸波，可以估计中心质量对爆炸的影响，SN 1987 A的前身的内核近似就是这种情况;它的参数是这样的，在冲击波阵面内核子密度基本恒定。在具有大质量包层的SN爆炸中，核心材料通过与包层的相互作用而减速，并且反向冲击波传播回中心。参考文献42篇。
An estimate can be made of the effect of a central mass on an explosion through the study of self-similar blast waves in a medium having an inverse-square-of-r density profile, as is approximately the case in the inner core of the progenitor of SN 1987A; its parameters are such that the nucleon density is substantially constant within the shock front. In SN explosions with a massive envelopes, the core material is decelerated by its interaction with the envelope, and a reverse shock wave propagates back to the center. 42 refs.
