质量比太阳小的恒星会比较小和比较冷，几乎不产生可见光。

Stars with less mass than the sun are smaller and cooler, and hence much fainter in visible light.

取而代之的是观点认为，这个明亮的恒星的质量还要小的多。

Instead, it is a bright star with a lot lessmass.

即使在这样较小的质量下，鉴于恒星和行星诞生的环境的不同，许多天文学家依然会将它划分为小质量恒星而不是行星。

Even at this smaller mass, however, many astronomers would still classify it as a low mass star rather than a planet, since the circumstances of birth for stars and planets differ.

在观测太过于遥远的星群时，要分辨出望远镜看到的是一颗重质量的恒星还是两颗小恒星靠得很近，总是不太可能。

In clusters that are too far away, it isn't always possible to tell if a telescope has picked up on one heavyweight star or two smaller ones in close proximity.

那些不到8个太阳质量的小恒星就会扩大成红巨星，最终缩小成白矮星。

Stars smaller than eight solar masses simply expand into red giants and then dwindle away into white dwarfs.

近30多年的观测研究使得天文学家对小质量恒星的形成有了相对明确的认识：小质量恒星通过坍缩、吸积和外向流的路标而形成。

Through almost 30 years observation and study, astronomers come to a relatively clear agreement that low mass stars form by collapse, accretion and outflow.
