1. Study for the Morphological Type of the Circumstellar Dust Shell of Herbig Ae/Be Star

2. Our conclusion is that we happened to observe an intensive short time-scale activity of the chromosphere of Arcturus characterized by mass outflow and outward motions of circumstellar matter.

分析认为我们观测到的是大角星的一次以天计的短时标色球剧烈活动，它伴随着物质的向外抛射，也引起星周物质的向外运动。

3. Another expectation, which Hubble overturned, was that the circumstellar disks would be deeply embedded within their parent clouds and would therefore be impossible to see.

另外有一个被哈伯推翻的猜测，是因为环绕恒星的气盘深藏在其母云气之中，所以无从窥其究竟。

9. 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。

10. Intense ultraviolet radiation from the core heats the circumstellar gas to ten thousand degrees, and the velocity of the gas flowing away from the star jumps to about a million miles per hour.

核心强烈的紫外辐射将星周气体加热到上万度，从恒星流出的气体速度跃升到了每小时百万英里。

12. Circumstellar star-forming rings are common in the universe.

绕核的恒星产生在宇宙中是很平常的。
