By being able to measure the distance between the black hole and the accretion disc
, we believe we can more effectively measure the spin of black holes.
They are thought to arise from the interaction of the secondary star orbit with a slowly precessing eccentric accretion disc
A quasar accretion disc
has a typical size of a few light-days, or around 100 billion kilometers across, but they lie billions of light-years away.
This program has two main objectives: 1) Develop the theoretical framework to incorporate magnetic fields, and the ensuing turbulence, into self-consistent accretion disc
models, and investigate their observational implications.
9, (11) where there is a relationship between eclipse depth and the precession period of the accretion disc
362,847) ($1,739,377) Preferred Stock Accretion Disc
He also concluded that the outburst is due to a thermonuclear runaway, as there is no evidence for any accretion driven event as eclipse profiles do not reveal the presence of a notable accretion disc
This material then flowed in towards the vampire, encircling it with a disc known as an accretion disc
The short duration and shallow nature of the eclipses suggests that these are grazing eclipses of the accretion disc
, with the binary system being only slightly above the critical inclination for eclipses to occur.
This phenomenon is known to astronomers as an accretion disc
In the absence of a significant white dwarf magnetic field, material from the secondary passes through an accretion disc
before settling on the surface of the white dwarf.
By recording the variation in colour, the team were able to reconstruct the colour profile across the accretion disc
, which is important because the temperature of an accretion disc
increases the closer it is to the black hole, and the colours emitted by the hot matter get bluer the hotter they are.
