- Similarly, in the turbulence scenario, chaotic gas motions can trigger the collapse of objects even smaller than the usual brown dwarf definition. 相同地,在乱流说里混乱的气体运动甚至可以激发小于一般棕矮星定义的物体坍塌。
- Macintosh's team used ground-based telescopes to spot three other planets orbiting a different star. That makes it less likely they are a pack of brown dwarf stars. 迈森多士的小组使用地面望远镜来准确定位围绕另一颗恒星运转的其它行星。这使得这些行星为褐矮星的可能性很小。

- 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。
- The dark star--named Nemesis by astronomers--is thought to be a brown dwarf" that spins round the Sun in an orbit so large it is measured in light years, the distance light travels in a year, equivalent to about 6,000 billion miles. 这颗被天文学家叫做复仇女神星的暗星被认为是一颗"褐矮星",它围绕太阳旋转的轨道大得要用光年计量,光年是光在一年中走过的距离,大约等于 6万亿英里。
- Dust grains in a disk absorb light from the central star or brown dwarf and reemit the energy at longer wavelengths, making objects with disks appear brighter in the infrared than those without. 气盘上的尘埃微粒会吸收中央恒星或棕矮星所发的光,并以较长的波长将能量再辐射出去,造成带有气盘的天体于红外光波段看起来,比不带气盘的天体来得明亮。
- The object, COROT-exo-3b, fits into the category of a failed star known as a brown dwarf, but the team that made the disc overy has not ruled out the possibility that it is a planet. 该天体叫做COROT-exo-3b,属于一类被称为褐矮星的失败恒星,但是发现该天体的研究小组没有排除它就是一颗行星的可能性。
- Whereas the ejection scenario does predict that brown dwarf disks should be truncated, it is still possible for ejected dwarfs to retain a small disk. 虽然排斥说的确预言棕矮星的气盘应被截断,但被排斥逐出的矮星仍有可能保留著小型气盘。

- 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。
- 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。
- So far, the mounting evidence all points to a remarkably similar infancy for both sunlike stars and brown dwarfs. 到目前为止,堆积如山的证据都指向太阳般的恒星与棕矮星,具有极相似的婴儿期。
- 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。

- Ironically, studying the formation of brown dwarfs calls into question the very definition of these objects. 讽刺的是,研究棕矮星的形成恰好对这些物体的定义提出疑问。
- 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。
- Recent observations hint at the existence of isolated brown dwarfs with masses of just a few Jupiters. 最近的观测暗示了宇宙里,确实有可能存在只有几个木星质量的独立棕矮星。
