Planets are believed to emerge from the accretion of particles in a disk of gas and dust as they whirl around the star.

行星被认为是由围绕恒星旋转的气体和尘埃组成的圆盘中的粒子累积而成。

We'd be able to connect a lot of the physics happening within the gaseous environment and accretion disk to the binary black hole merger to the gravitational radiation.

我们可以将很多发生在黑洞对合并时的气体环境和吸积盘里的物理过程与引力辐射联系起来。

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。

As matter goes in and gathers into what is called an accretion disk, it heats up and emits X-rays.

BBC: First glimpse of a black hole's spin

Proga and his colleagues hypothesize that intense ultraviolet light emanating from the accretion disk region produces two types of winds.

These winds are generated in a swirling mass of matter around the equatorial region of a black hole, the accretion disk.
