All that carbon and oxygen — byproducts of the heliumfusionprocess — 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。

The energy of the Sun arises not from any burning process but from nuclear fusion, the transformation of hydrogen into helium, in part by a complicated process involving carbon and nitrogen.
