这个新模型追踪了海王星轨道外数无数个微小物体的运行轨迹，它可以帮助天文学家计算出其他星系尘埃盘中行星的特性。
The new model, which tracks thousands of tiny particles beyond the orbit of Neptune, could help astronomers work out the properties of planets in other stars' dust disks.
就它们与恒星的距离而言，其石质行星核恐怕需要极其长的成型时间，以至于在星核能够俘获气体前周围的气态盘恐怕就已经消散殆尽了。
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.

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。
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.

这里可以看见它的已知3个卫星：冥卫1，冥卫2，和冥卫3。 包括冥王星在内的一群物体，在海王星的凯伯带（数十亿颗在海王星轨道之外绕行的小型冰体构成的碟形带）之上，围绕着太阳的作盘形轨道运行。
Seen here with its three known moons, Charon, Nix, and Hydra, Pluto is a member of a group of objects that orbit in a disklike zone beyond the orbit of Neptune called the Kuiper belt.
后来的数值模拟结果显示出，即使伴星的轨道半径大如海王星的轨道，它仍可汲取物质而形成吸积盘。
Later simulations show that even a companion with an orbit as wide as Neptune's could scoop up an accretion disk.
NGC 2976不像典型的涡旋星系：它有一个星暴盘，但看不到旋臂；
NGC 2976 does not look like a typical spiral galaxy. It has a star-forming disk, but no obvious spiral pattern.
比如在我自己的命盘中，土星合海王星，刑天王星，拱木星，这代表对我而言最高层次的成就是来自于精神上的。
In my own chart for example, Saturn is conjunct Neptune, squaring Uranus and trining Jupiter. This means for me that the highest level of achievement is spiritual.
本文中我们利用盘不稳定模型和星爆模型的基本思想，模拟活动星系核在光学波段的光度和光谱斜率变化，并将模拟的结果和观测进行比较。
In this paper, using disk-instability model and starburst model, the AGN optical variability and spectral slope variability are simulated and confronted with observations.

The gnomon in the middle is perpendicular to the plate, parallel to the earth's axis, and points to the celestial North Pole (near the north Star).
该图像突出了星系的结构：一个微妙的，围绕着一个明亮的红色隆起核，并联运行的尘埃带星蓝盘，以及一个透明的外晕。
The image highlights the galaxy's structure: a subtle, reddish bulge surrounding a bright nucleus, a blue disk of stars running parallel to the dust lane, and a transparent outer halo.
