| 1. | Brown dwarfs can then form directly from ultralow - mass cores
棕矮星因此能够在超轻云核里形成。 |
| 2. | Proto - brown dwarf
原褐矮星 |
| 3. | For these reasons , astronomers favor a more starlike formation scenario for brown dwarfs
因为这些理由，天文学家认为棕矮星的起源，较倾向恒星形成的方式。 |
| 4. | If that happens before the embryo has had time to attain stellar mass , the result is a brown dwarf
假如这发生在胚胎达到恒星质量之前，结果就是一颗棕矮星。 |
| 5. | We find that disks are in fact ubiquitous around brown dwarfs that are a few million years old
事实上，我们发现在年龄为数百万年的棕矮星旁，到处可见气盘的存在。 |
| 6. | In short , brown dwarfs are girdled by disks just as often as stars are , and their disk lifetimes are similar
总而言之，棕矮星被气盘环绕的情况与恒星一样常见，而且它们气盘的寿命都差不多。 |
| 7. | In the turbulence scheme , such binary systems should be nearly as common among brown dwarfs as among stars
在乱流说的架构下，这种双星系统发生在棕矮星上的机率，应与发生在一般恒星上相当。 |
| 8. | What , then , accounts for brown dwarfs , which tip the scales at merely a few tens of jupiters ( a few hundredths of a solar mass )
那麽，如何才能解释棕矮星仅有数十颗木星的质量（太阳质量的百分之几）呢？ |
| 9. | The ejection scenario , on the other hand , attributes brown dwarfs to dynamical interactions that can toss an embryo out of the molecular cloud
另一方面，排斥说将棕矮星归因于将胚胎扔出分子云的动态交互作用。 |
| 10. | If the turbulence scenario is correct , young brown dwarfs , too , should have disks and maybe even planets [ see box on page 45 ]
假如乱流说是正确的，年轻的棕矮星也应有气盘，甚至拥有行星（参见93页棕矮星也有行星吗？ |
