Animation of a Cataclysmic Binary
... er Lagrangian (or L1) point – spills over towards the white dwarf and flows towards it, forming a pancake of gas called an accretion disc. From here, the gas makes its way to the surface of the white dwarf. If the white dwarf accumulates too much m ...

Be X-Ray Binary
... his image shows, gas from the Be star's circumstellar disc flows towards the neutron star and surrounds it in a much smaller accretion disc. This gas is heated to very high temperatures, emitting x-rays. When the neutron star is far from the Be star, ...

Cygnus X-1
... s from its giant companion and that gas flows towards the black hole and then around it – to form what astronomers call an accretion disc. There is no bridge of matter between the objects, though, because the blue star is not sufficiently distorted ...

High-Mass X-Ray Binary
... hly compact partner. Gas flows from the blue giant towards the black hole/neutron star and forms a gaseous pancake called an accretion disc. As it spirals to its doom, the gas is heated to very high temperatures, leading to the emission of x-rays, fr ...

Intermediate Polar
This picture shows a magnetic cataclysmic variable called an intermediate polar. The white dwarf and its magnetic field are spinning around very quickly where the centre of the accretion disc would be, removing its central regions. In its place is a ...

Low-Mass X-Ray Binary II
This image shows a low-mass x-ray binary star seen from a nearby, hypothetical asteroid field. The system consists of a red dwarf (bottom) which is losing its atmosphere to a black hole via an accretion disc....

M87 Black Hole
Artwork of the M87 black hole seen from a nearby planet. M87's central black hole was famously imaged in 2019 by a team of astronomers using the Event Horizon Telescope. It is the first ever image of a black hole's accretion disc that has been direct...
