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。
If the star is really big—and here we’re talking more than 130 solar masses—the collapse happens so fast and gathers so much inertia that even fusing oxygen can’t stop it.
如果这颗恒星确实足够大--我们在这谈到的是相当于太阳130倍的规模--这个崩塌过程十分迅速，惯性十分巨大，以致于氧聚变无法停止。
This and the X-ray spectrum, which exhibits a high concentration of iron atoms relative to oxygen and silicon, convincingly show that the ejecta are the remains of an exploded white dwarf star.
这幅图连带X射线光谱（显示出了铁相对氧与硅的高度集中）令人信服地说明，抛出的物质是爆发白矮星的残余。
