恒星的质量越大，它消耗氢燃料的速度也就越快，它在主序中停留的时间也就越短。

The greater the mass of such a star, the more quickly it will use its hydrogen fuel and the shorter it stays on the main sequence.

这颗恒星曾和太阳一样，是颗“主序星”(“main sequence”)。它通过核聚变燃烧氢，从而产生氦。

The star used to be like the sun, a "main sequence" star that burns hydrogen by nuclear fusion, producing helium.
