At their distances from the star, the rocky planetary core would have taken so long to form that the gaseous disk would have dissipated before the core could attract the gas.

They go around in the plane of the blackboard, say, and so this matter cannot fall radially in but it will fall in and spiral in and forms what we call an accretion disk around the neutron star.
平面内绕行，这个质量不是，呈放射状减小，而是，呈螺旋形减小，我们称之为中子星，周围的吸积盘，这个叫做吸收星。
If the swirling disk of gas is massive enough-one-tenth the mass of its star or more-johns-krull says the gravitational power of the disk can make the disk unstable.
如果漩磁盘的气体足够大—它的恒星的十分之一或更多—磁盘的重力能够是磁盘动荡，约翰斯说到。

Astronomers inferred the planet's presence from an enormous hole in the dusty disk that girdles the star.
天文学家们猜想这颗行星存在于一个绕着恒星满是尘埃的圆盘中的一个大洞中。
The new model also holds that the companion object is a so-called "B star" circled by a dusty disk.
这个新模型依然坚持的观点是那个被称为“B星”的伴星被星尘带所环绕。
Astronomers have found a disk of dust around a huge, massive star in its early stages of growth, indicating that stars big and small form by the same mechanism.
天文学家发现一个碟状的尘埃围绕着一个巨型星体，该星体正在它的成长阶段，说明星体无论大小，形成的机制是一样的。
A region of gas and dust from exploding stars in the Milky Way galaxy starts to collapse under its own gravity, forming a small star surrounded by a disk of rocky material and gas.
银河系漩涡展开过程中某些区域的星群之气体尘埃在引力作用下，形成由岩石物质和气体包围的小行星。
Star in May, we open the computer, to our youth praise of Labor and the importation of the hard disk.
在五月星空下，我们打开电脑，把我们对劳动和青春的赞美输入硬盘。
They found the star to be surrounded by a so-called circumstellar disk measuring some 130 astronomical units (12 billion miles) across.
他们发现围绕星体的碟状物质直径大约130天文单位(120亿英里)。
In this model, gas flows from the large red giant companion star into a disk and then onto the White Dwarf.
这个模型是指气体从大型红巨星伴星流到白矮星的吸积盘上然后被吸进白矮星中。
As the accretion disk feeds more mass into itself, the embryo star contracts, growing ever denser and more massive.
随著吸积盘获得越来越多的物质，胚胎恒星就不断收缩，密度和质量都变得越来越大。
The image shows a young sun-like star encircled by its planet-forming disk of gas and dust.
图中，由气体、尘埃等组成的原始行星盘围绕着一颗与太阳质量类似的早期恒星，而硅酸盐构成了大部分尘埃。
NGC 2976 does not look like a typical spiral galaxy. It has a star-forming disk, but no obvious spiral pattern.
NGC 2976不像典型的涡旋星系：它有一个星暴盘，但看不到旋臂；
Even on the brightest star, like Vega, it showed a well-defined air-disk.
即使是最闪亮的一颗星，织女星一样，它表明一个清楚界定的空磁盘。
The tsunami of gas racing toward the center has fueled rapid star birth for at least the past 500 million years in the relatively armless disk.
