恒星核心中发生的核聚变产生热能与向外的压力，不过这份压力由恒星质量所产生的内向重力抵消了。
Fusion in a star's core produces heat and outward pressure, but this pressure is kept in balance by the inward push of gravity generated by a star's mass.
这时核聚变将在恒星表面发生，而不再是其在核心了。
Instead of fusion taking place in the stellar core, it fizzles towards the surface.
大质量恒星死亡时，它们通常运行的材料进行维持核聚变，以及所有在其核心的左边是惰性铁。
Massive stars normally die when they run out of material to sustain nuclear fusion, and all that's left in their cores is inert iron.
