The moment the accretion process ended the planet began to cool.

这个过程结束时候，火星便开始冷却。

Assuming it's spinning in the same direction as the matter in the accretion disk.

这是在黑自旋与吸积盘旋转方向相同情况下。

The program made a rough attempt to simulate the accretion process in the early solar system.

程序粗略地模拟了早期太阳系成长过程。

The accretion process creates heat and heavier particles sink to the center of the accumulating mass.

增长过程产生了热量，较重粒子下沉到物质团中心。

You can actually so something very similar for a black hole's accretion disk.

利用类似方法算出黑吸积盘。

Its mass fell in towards the black hole forming an accretion disk.

恒星物质形成了黑吸积盘。

They'd swarm in an orbit around a black hole, perhaps on the plane of its accretion disk, but farther out.

它们沿着环绕黑轨道成群移动，远离吸积盘，但与其保持在同一平面上。

Who used the Newtonian treatment of accretion?

谁用到了牛顿定律?

So when you're looking at a black hole that is feeding, the innermost edge of the accretion disk is at r-isco.

当看到正在吞噬恒星黑时，吸积盘内边缘就是ISCO。

Accretion onto a stationary black hole has been solved analytically only under the assumption of spherical symmetry.

在球对称假设条件下静态黑增长问题 已经得出了分析结果。

But this method only works if the radiation from the black hole is dominated by black-body radiation from the accretion disk.

但是这种方法只能在吸积盘为主要黑体辐射时使用。

Many exoplanets' star systems are flat, a lot of galaxies are flat, black hole accretion disks are flat, Saturn's rings are flat, etc.

很多系外行星恒星系统是平，许多星系是平，黑吸积盘是平，土星环是平，等等。

If the accretion disk is tipped a bit to out line of sight we see more optical and high energy light from it.

如果吸积盘向我们视线外倾斜一点，我们就能从它那里看到更多高能光。

Active galaxies can look pretty different from each other, and we now think that's due to our viewing angle on their accretion disk.

活动星系之间能看起来非常不同，我们现在认为这是由于我们观察它们吸积盘角度不同造成。

Though I guess you could also have spins down to -1 if the black hole is spinning in the opposite direction from the accretion disk.

当黑自旋与吸积盘旋转方向相反时，这个数也降到-1。

This material forms a flat disk called an accretion disk, the matter swirling madly at ferocious speeds before falling in like water down a bathtub drain.

这些物质形成了一个被称为吸积盘扁平圆盘，在像浴缸排水管中水一样下落之前，这些物质会惊人速度疯狂旋转。

This then mimics what happens in a hypernova: it becomes an accretion disk, heated to ridiculous temperatures, blasting out those beams of matter and energy.

它变成一个吸积盘，被加热到荒谬温度，喷出那些物质和能量束。

Black holes don't generate a lot of energy unless they happen to suck down a large amount of material that can be torn apart and turned into an accretion disk.

黑不会产生很多能量，除非它们碰巧吸收了大量物质，这些物质被撕成吸积盘。

When the core of a VERY massive star collapses, forming a black hole, the material just outside the core falls down, forming an incredibly hot swirling maelstrom called an accretion disk.

当一个非常大恒星核心坍塌，形成黑时，核心外物质会下降，形成一个非常热漩涡，称为吸积盘。

It's counterintuitive to think of black holes as energy sources, but that's exactly what they are, thanks to their accretion disks: circular, flat structures formed by matter falling into the event horizon.

把黑视为能量来源是一种反直觉想法，但它们自然特性就是如此。这要归结于它们吸积盘（Accretion disk）：一种圆形扁平结构，由掉落在事件视界（Event horizon）内物质构成。
