But two recent studies suggest that these "failed stars" are nevertheless more like stars than planets, displaying strong polar jets and accretion disks
like those seen around forming stars.
After carefully examining several possibilities, the team concluded that huge amounts of gas are rapidly falling onto "little monster" black holes in each of these ULXs, which produces a dense disk wind flowing away from the supercritical accretion disk
The accretion disk
is searingly hot and quite massive, and can linger around a young star for 10,000,000 years or so.
Light will not come out straight from Sgr A*'s accretion disk
but will bend as the powerful gravity warps time and space.
SS 433-The parameters of the eclipsing system with a processing thick accretion disk
Both young and old, astronomers say, may be characterized by an accretion disk
The added blue light surely comes from the white dwarf and/or its accretion disk
The computer code was used to create images of the movie's wormhole and the black hole, Gargantua, and its glowing accretion disk
, with unparalleled smoothness and clarity.
As gas falls toward a supermassive black hole, it gathers into a so-called accretion disk
and becomes compressed and heated, ultimately emitting X-rays.
Since there is a direct relationship between the jets and a star's accretion disk
, there is a great deal to be learned about stellar formation by simply studying the jets.
Sixty-nine papers from the October 2011 conference present research on the physical characteristics of active galactic nuclei (AGN) accretion disk
It is believed that stars and gas whirl into the maelstrom of gigantic, supermassive black holes, and that this in-falling swirl of material creates a huge disk, called an accretion disk
