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。
And the heavier oxygen from a natural process that left more of the light isotope in the part of the nebula that made the sun. So we are made of star stuff.
重量较大的氧来自某种自然过程，在此过程中，大部分的轻同位素留在了形成太阳的部分星云中。
Our aims are to study the oxygen abundance of the star-forming galaxies, to study the estimating methods and the calibration relations.
本论文主要研究了恒星形成星系的氧丰度，测量方法以及定标关系。
The team chose a star-forming region in the constellation Orion, believing that oxygen would be "baked off" from the ice and dust in a warmer, more turbulent part of space.
研究小组选择在猎户座的一个恒星形成区观测，他们认为氧气在一个温暖的不稳定的条件下将从尘埃和水冰中挥发出来。
A spokesman for Bieber says the 19-year-old pop star was given oxygen and took a 20-minute break backstage at London's O2 Arena.
