Be X-Ray Binary
Here is a different kind of x-ray binary. In the foreground (top) is a hot star called a Be star. It spins so quickly that it is surrounded by a circumstellar disc of matter, flung off via centrifugal force. The Be star is in orbit around a tiny and ...

Cataclysm VI
... he red dwarf. It gas flows away from it and plunges towards and around the white dwarf, where it forms a so-called accretion disc. ...

Cygnus X-1
... 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. Instead, ...

High-Mass X-Ray Binary
... t 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, from which t ...

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...

When Black Holes Collide
... galaxies, Abel 400. At the moment the two black holes in Abel 400 are widely separated, each surrounded by a vast accretion disc of gas and dust. For this picture, though, I imagined the scenario in several billion years, when the holes reside in a ...
