When a disk of material called an
accretion disk rotates around a black hole on a tilted axis, it wobbles around in a movement that also affects those jets, according to the simulation.
will form what is called an
accretion disk orbiting just around the black hole.
Yet the 2 million-year-old object is growing from an
accretion disk, as stars do.
By looking at these quasars in both optical and infrared wavelengths, the team could probe both the quasar's
accretion disk and its torus " the doughnut-shaped ring of dust clouds that wraps around it.
As matter from the star falls onto the black hole, an
accretion disk forms around the black hole.
But now and then the stream surges, pushing its way closer to the pulsar and establishing an
accretion disk.
The remaining mass flattened out into a pancake-like protoplanetary
accretion disk from which the eight major planets and their numerous moons, comets, asteroids, and other small solar system bodies emerged.
And the innermost stable circular orbit around the black hole, the brightly glowing edge of the
accretion disk, will be about three times wider.
In case of a neutron star or a white dwarf the emission originates from both the
accretion disk and the surface of the compact star while in black hole binaries the only source of X-rays is the
accretion disk.
Although the birthing of planets and dying of paired stars are similar in that they both occur within an
accretion disk, a pancake of diffuse matter, they are also notably different.
The S results from a bipolar jet of hot material flying from the poles of an
accretion disk around the white dwarf.
Specific topics include
accretion disk winds by magneto-rotational turbulence, the origin of magnetic fields in the intracluster medium, the long-term sustainability of Rossby wave instability in proto-planetary disks with dead zones, computational physics of small meteors, the marriage of gas and dust, and well-balanced schemes for gravitationally stratified media.
