The high mass star has lost its outer layers, and is a dense white dwarf.

这颗大质量恒星已经失去了外层，成为了颗致密星。

A black hole is the ultimate end state for the core of a high mass star.

黑洞是大质量恒星核心终极状态。

The Sun probably won't form one, but higher mass stars do.

太阳可能不会形成它们，但大质量恒星会。

A lot of the material leaving the higher mass star gets dumped on the red dwarf, which starts to grow.

很多离开大质量恒星物质被转储到红星上，红星开始成长。

A higher mass star squeezes hydrogen harder, so it fuses far more quickly.

质量越高恒星对氢挤压就越厉害，所以它聚变速度就快得多。

Very roughly speaking, we can divide stars into two groups: low mass stars and high mass stars.

非常粗略地说，我们可以把恒星分成两组：低质量恒星和高质量恒星。

It starts with the lowest mass stars, but as they leave even higher mass stars can be lost this way.

它从最小质量恒星开始失去，但随着它们离开，甚至质量更大恒星也会以这种方式流失。

But astronomers figured out they're actually stars that have physically collided and merged to form a single, higher mass star.

但是天文学家发现，它们实际上是恒星经过物理碰撞与合并，从而形成、更大质量恒星。

So a higher mass star, more than about eight times the mass of the Sun.

所以颗质量更大恒星，大约是太阳质量八倍以上。

They were so troubled in mind that they missed high Mass, and only went to the military service.

她们心事重重，错过了高弥撒，只去了军用弥撒。

So it's only these high mass stars that can do that supernova as the end of their life.

所以只有这些高质量恒星才能在生命尽头发生超新星爆发。

But higher mass stars are doing this kind of interior to themselves.

但质量更大恒星会在自身内部进行这种过程。

They would have been commoner in the past when the short-lived high mass stars star stars were more abundant.

在过去，当寿命较短高质量恒星更为丰富时，它们会更加常见。

Because of its high mass, when the white dwarf passes in front of its mate its gravity bends and amplifies the larger star's light, just as Einstein said.

由于其高密度，当这颗星运动到它同伴前面时，自身重力发生弯曲并使得较大那颗恒星发出光线被增强，就如同爱因斯坦曾经描述那样。

But when a higher mass star gets to a certain point, it's burning through heavier and heavier elements.

但当颗质量更大恒星达到某个阶段时，它就会燃烧越来越重元素。

When we look at that binary system, we see a white dwarf star that is clearly more evolved than a high mass one, the opposite of what we expect!

当我们观察这个双星系统时，我们看到是颗星，它进化程度明显比大质量恒星要高，这与我们预期相反！

The last stage is known as High Mass Consumption – when your country is big enough that production becomes more about wants than needs.

最后个阶段被称为高大众消费——当你国家足够大，生产更多是为了满足欲望而非需求。

But in terms of the end stage of a star, it's only the high mass ones that die by blowing up as a supernova.

但在恒星生命终末阶段，只有高质量恒星会以超新星爆发形式死亡。

Way back in Episode 7, I talked about escape velocity, and it's about to become a major player in the unfolding events of the collapsing core of a high mass star.

早在第7集，我就谈到了逃逸速度，它将成为大质量恒星坍塌核心展开事件主要因素。

Those high mass stars have a much different and far more explosive fate than lower mass stars like the Sun… and trust me, we'll cover that in lots of fun detail soon.

那些大质量恒星命运与像太阳这样小质量恒星大不相同，爆炸几率也大得多… … 相信我，我们很快就会详细讨论这个问题。
