Investigation of the accretion disk structure in binary stars.
Discovery of precessional density waves in cool accretion disks.
In an accretion disk, there is a net flux of mass from larger radii toward smaller radii.
This appears to have been caused by the loss of the accretion disk.
Alternatively, planets may form in an accretion disk of fallback matter surrounding a pulsar.
The concept of area density can be useful when analysing accretion disks.
The accretion disk can become thermally stable in systems with high mass-transfer rates Ṁ.
The brightest part of the system is the accretion disk around the compact object.
Such jets are believed to be created by the interaction of the central black hole and the accretion disk.
It may suggest the presence of a high temperature accretion disk within a binary star system.
The latter have accretion disks and continue to accrete hot gas, which manifests itself by strong emission lines in their spectrum.
A stellar wind from the star provides material for an accretion disk around the X-ray source.
AM CVn systems consist of an accretor white dwarf star, a donor star consisting mostly of helium,and usually an accretion disk.
It is likely that Oberon formed from the accretion disk that surrounded Uranus just after the planet's formation.
In most cataclysmic variables,matter from the companion star is gravitationally stripped by the compact star and forms an accretion disk around it.
In addition, the giant planets probably had accretion disks of their own, in the first meaning of the word.
Accretion disks of young stars and protostars radiate in the infrared; those around neutron stars and black holes in the X-ray part of the spectrum.
An isolated black hole, however, would not have an accretion disk and would only be detectable by gravitational lensing.
This supports a hypothesis concerning the possibility that the metallicity of stars during their births may determine whether a protostar's accretion disk forms gas giants or terrestrial planets.
The same process is expected to produce accretion disks around virtually all newly forming stars in the universe, some of which yield planets.
As is the case with dwarf novae, the outbursts are theorized results of a periodic surge of influx from the white dwarf's accretion disk, caused by instability in the disk itself.
The energy output from the mass flow onto this accretion disk is actually the primary contributor to the visual luminosity of this system; outshining both of the stellar components.
The pulsar has a spin period of 685 seconds, but shows relatively large spindown rates thought to be due to its strong magnetic field, andalso occasional spinups due to interaction with the accretion disk.
First investigations of the influence of magnetic field on the accretion disk structure in the intermediate polars.
The protoplanetary disk is sometimes referred to as an accretion disk, because while the young T Tauri-like protostar is still contracting, gaseous material may still be falling onto it, accreting on its surface from the disk's inner edge.
In 2014, astronomers found that the X-rays being emitted are coming from a region inside the accretion disk located about three times the radius of the event horizon.
The protoplanetary disk may also be considered an accretion disk for the star itself, because gases or other material may be falling from the inner edge of the disk onto the surface of the star.
Microquasars are named after quasars, as they have some common characteristics: strong and variable radio emission,often resolvable as a pair of radio jets, and an accretion disk surrounding a compact object which is either a black hole or a neutron star.
Since the lobes are produced by jets that are launched perpendicularly to the inner accretion disk, and since the accretion disk is constrained by the Bardeen-Petterson effect to lie perpendicular to the black hole's spin axis, a change in the spin orientation implies a change in the direction of the lobes.
Like all major moons of Uranus,Titania probably formed from an accretion disk which surrounded the planet just after its formation.
