Gravity and thermal energy are universal phenomena which compete over the stabilization of astrophysical systems. The former induces an inward pressure driving collapse and the latter a stabilizing outward pressure generated by random motion and energy dispersion. Since a contracting self-gravitating system is heated up one may wonder why is gravitational collapse not halted in all cases at a sufficient high temperature establishing either a gravo-thermal equilibrium or explosion. Here, based on the equivalence between mass and energy, we show that there always exists a temperature threshold beyond which the gravitation of thermal energy overcomes its stabilizing pressure and the system collapses under the weight of its own heat.

热质量引起的相对论引力坍塌

重力和热能是普遍现象,它们与天体物理系统的稳定性竞争。前者引起驱动坍塌的向内压力,后者由随机运动和能量分散产生稳定的向外压力。由于收缩的自引力系统被加热,人们可能想知道为什么在足够高的温度下引力坍缩不会在所有情况下停止,从而建立重力热平衡或爆炸。在这里,基于质量和能量之间的等价性,我们表明始终存在一个温度阈值,超过该阈值热能的引力克服其稳定压力,系统在其自身热量的重量下崩溃。
