What is "accretion disks"

Usage examples of "accretion disks".

But, chiefly, it's coming from that whirligig of black holes and their accretion disks.

The gas and dust from nearby stars was being pulled into the accretion disks in long, attenuated streamers of blue-white and rose.

The watching eyes of the accretion disks seemed to widen and narrow as the Falcon soared and swooped in and around the treacherous gravity wells.

Collisions with cosmic debris around the black holes and radiation flashes from their accretion disks have caused such periodic events of mass extinction as the disappearance of the dinosaurs.

Certainly our experience with distant, active galactic nuclei leads us to suspect one, since the galactic jets I had already studied almost certainly come from the accretion disks around truly massive black holes, some ranging up to perhaps a billion stellar masses.

They had woven in and out of the tendrils of gas, charting the infalling masses and exploring the rocky accretion disks of stars entering the main sequence.

I've only read about them, of course-miniature accretion disks that emit a luminous beam of energy.

There were a few fairly irrelevant questions about stuff like accretion disks, lunar tidal forces, and conservation of angular momentum, but after Li had done his best to answer those, Roghres, Tel, Djibard and I went to the head of the table, lifted Li up, carried him down the length of the table to the sound of cheers, took him into the lower accommodation level, and threw him in the pool.
