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.
所有氦聚变中的附产物碳和氧在它的核心逐渐积聚，这期间它将失掉较外层物质，核心最终枯萎成为白矮星。
Red giants are hot enough to turn the helium at their core, which was made by fusing hydrogen, into heavy elements like carbon.
红巨星的温度足够高，可以将其核心中由氢聚变成的氦再转变为重元素，比如碳。
Under such extreme conditions, which are found only in the core of stars, the hydrogen atoms will fuse, producing helium and vast amounts of energy.
在这种原本只能发生在恒星内部的极端条件下，氢原子将发生聚变反应而生成氦原子，同时释放出大量能量。
