新的弱相互作用粒子将从超新星核心出现，具有100 MeV的能量范围，并通过随后的衰变产生$\gamma$-射线。这将有助于扩散的宇宙$\gamma$-射线背景或将出现在太阳最大使命（SMM）卫星从SN~ 1987 A。然而，我们的例子的轴子状粒子（ALP），即使在距离超过祖星星，衰变光子可能无法逃脱，而是可以形成一个火球，等离子体壳与$T\lesssim 1$兆电子伏。因此，现有的论点并不排除具有几个10 MeV质量和几个10 ^{-10}~{\rm GeV}^{-1}$的双光子耦合的ALP。然而，能量将以亚MeV光子的形式出现，这在先锋金星轨道器（PVO）的SN 1987 A中没有看到，再次关闭了这个新窗口。对于以类似方式约束的其他粒子，需要进行仔细的重新评估。
New feebly interacting particles would emerge from a supernova core with 100-MeV-range energies and produce $\gamma$-rays by subsequent decays. These would contribute to the diffuse cosmic $\gamma$-ray background or would have shown up in the Solar Maximum Mission (SMM) satellite from SN~1987A. However, we show for the example of axion-like particles (ALPs) that, even at distances beyond the progenitor star, the decay photons may not escape, and can instead form a fireball, a plasma shell with $T\lesssim 1$ MeV. Thus, existing arguments do not exclude ALPs with few 10 MeV masses and a two-photon coupling of a few $10^{-10}~{\rm GeV}^{-1}$. However, the energy would have showed up in sub-MeV photons, which were not seen from SN 1987A in the Pioneer Venus Orbiter (PVO), closing again this new window. A careful re-assessment is required for other particles that were constrained in similar ways.
