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.
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。

Instead of fusion taking place in the stellar core, it fizzles towards the surface.
这时核聚变将在恒星表面发生,而不再是其在核心了。

All that carbon and oxygen — byproducts of the helium fusion process — build up in its core. At that point the star will shed its outer layers and the core will form a White Dwarf.
