- dust disks around young stars 绕年轻恒星和主序星的星周尘埃盘
- Astronomers used Hubble to confirm that planets form in dust disks around stars. 天文学家使用哈勃证实了行星形成在恒星周围的尘埃盘。
- Dust disk around a black hole in galaxy NGC 4261. 银河系4261号星云中的围绕黑洞的一个碟状星尘。
- Circumstellar disks around young stellar objects (YSOs) are a crucial component in the process of star formation, and are as well the sites where planetary systems are formed. 星周盘是恒星形成必不可少的成分，也是形成行星系统的场所。
- Scientists believe this process explains how protoplanetary disks form around young stars and perhaps how gas disks coalesce around black holes at the centers of galaxies. 科学家认为此过程解释了为什麽在年轻恒星周围会形成原生行星盘，或许也能解释在星系中心，气体盘如何与黑洞结合。
- Vast walls of dust hide and redden other hot young stars. 巨大的尘埃墙遮蔽了其他年轻的恒星，把它们“染”成红色。
- Disks have also been observed around many young stars; astronomers often call them protoplanetary disks because they appear to be similar to the one that must have formed our own solar system. 许多年轻恒星的周遭也可发现圆盘的踪影；天文学家通常称它们为原生行星盘，因它们看来与太阳系所赖以成形的那个圆盘类似。
- A similar effect flattens the debris disks around stars and the gaseous disks of spiral galaxies. 类似的效应也会出现在恒星周围的残馀盘，以及螺旋星系周围的气体圆盘上。
- Both tower-like nebulas are cocoons of young stars. 鹰状星云是著名的恒星出生地。
- The bright young stars in M25 appear blue. M25内明亮的年轻恒星看上去显蓝色。
- Astronomers have seen hints of gaps and resonances in the dusty disks around other stars, as well as signs that source bodies orbit within. 天文学家已经看到徵兆，环绕在其他恒星周围的尘埃圆盘，有隙缝与共振现象，而且提供物质来源的物体也运行于其中。
- Behind the dark lane lies a cluster of hot, young stars, seen at infrared wavelengths through the obscuring dust. 在黑暗尘埃带的后方有一个炽热的年轻恒星团，在红外波段下能透过模糊的尘埃看到它的存在。
- Explanation: Bright young stars sometimes sculpt picturesque dust mountains soon after being born. 说明： 在诞生后不久，有些明亮的年轻恒星会侵蚀出独特的尘埃山脉。
- A young star still might walk away from it all. 这位年轻的明星还是有可能离开演艺圈。
- Where the otherwise obscuring dust clouds lie close to the hot, young stars they also reflect starlight, forming blue reflection nebulae. 另一方面模糊的尘埃云靠近年轻炽热恒星的地方会反射星光，形成蓝色的反射星云。
- By analyzing numerically the disks around a young stellar object (YSO) and a black hole, we can obtain:(1) The dissipation can not be neglected as the magnetic field is in small threshold value. 通过分析年轻恒星周围和黑洞周围吸积盘的数值解可以得到:(1)在磁场比较小的一段阈值内;这种耗散过程是不可忽略的.
- At least half the young stars surveyed possess such disks, demonstrating that the raw materials for planet formation are ubiquitous in the galaxy. 观测到的年轻恒星至少半数以上具有这样的气盘，显示星系中到处充斥著这些制造行星的原始材料。
- Further out, when the radiation from these hot young stars becomes too weak to ionize hydrogen, the gas and dust instead glows by reflecting the original blue light. 另外，当来自这些炽热的年轻恒星的射线减弱到不能将氢电离时，气体和尘埃通过反射本来的蓝色光线发亮。
- My group and others are trying to figure out how MRI works in hot, opaque accretion disks around black holes. 包含我的研究群在内，天文学家正试著了解mri如何作用在黑洞周边高热而不透明的吸积盘。
- He dresses many of Hollywood's most famous young stars. 他为好莱坞许多最著名的年轻明星提供服装。
