当一颗陌生恒星表面的电场不能再支撑外壳时，整个外壳可能会落入核心。对这一过程的研究可能为观测识别奇异恒星提供一些理论线索。数值计算表明，底部密度约为8.3 × 10(10) g cm（-3）或质量约为3.4 × 10(-6)M（.）的地壳在约5.4 × 10(-3) s的时间内坍缩可能导致持续约0.15 s的爆炸事件，其中每个重子释放约6.3 MeV的能量，总辐射能量可能高达约10(46)- 10(47)erg。这可以用来解释宇宙中的一些爆炸现象。
When the electric field on the surface of a strange star can no longer sustain the crust, the whole crust may fall into the core. The study of this process may provide some theoretical clues for observational identification of strange stars. As shown by the numerical calculations, the collapse of a crust with bottom density of similar to 8.3 x 10(10) g cm(-3) or mass of similar to 3.4 x 10(-6)M(.) in a time of approximately 5.4 x 10(-3) s may lead to an explosive event lasting about 0.15 s, in which every baryon releases an energy of approximately 6.3 MeV, and the total radiative energy may be as high as similar to 10(46) - 10(47) erg. This can be used to interpret some explosive phenomena in the universe.
