That kind of light can pierce the dark disk, and when we use infrared telescopes we can see the protostars forming in the centers of those disks.

这种光可以穿透黑色的星盘，当我们使用红外望远镜时，我们可以看到星在星盘中心形成。

The object forming there was a protostar — or, spoiler alert, the protosun.

那里的物质形成星，或者说，剧透警告哦，就太阳的前体。

So you'll start to form a protostar.

于开始形成颗星。

He was one of the first people to suggest that young stars formed from protostars.

他首提出年轻星由星形成的学者之。

And a protostar is basically the young star of, you know, this ball of gas where nuclear reactions are getting started, but it's also a disk.

星基本上颗年轻的星，知道， 这颗气体球中的核反应刚刚开始，但它也个圆盘。

Infrared space telescopes, such as Spitzer and Hubble, have given faint glimpses of protostars, but mostly they are too heavily shrouded by the dark dust clouds.

红外空间望远镜， 如斯皮策和哈勃，已对星提供了模糊的窥视，但多数情况下， 它们被浓密的黑暗尘埃云严重遮蔽。

Unlike an adult star, a protostar releases its heat entirely by a process of convection.

与成年星不同，星完全通过对流过程释放其热量。

The protostar warms up as it becomes denser, but it is still too small and cold to produce energy by fusing hydrogen in its core.

星随着密度增加而升温，但由于其体积过小、温度过低， 尚无法通过核心氢聚变产生能量。

Hsu worked on his protostar model while at Berkeley and was the head of the astronomy department there by the time he presented the full review of his isothermal sphere model in 1986. Today, Hsu holds tenure at Berkeley.

徐遐生在伯克利期间致力于其星模型研究， 并于1986年全面回顾其等温球模型时， 已担任该校天文系主任。如今，徐遐生在伯克利享有终身教职。
