Sentences with phrase «discs around black holes»

Previous work had unified the variability in discs around black holes of different mass ranges, but by considering not just the mass of the object, but also its size, scientists can now add accreting white dwarfs and proto - stars to this unified picture.

Kip Thorne worked out the mathematics of what happens to the accretion disc, and found that the intense gravity warps the disc around the black hole, creating the spectacular halo that is one of the movie's visual highlights.

The corona gives off X-ray light that has a slightly different spectrum — X-ray «colours» — than the light coming from the disc around the black hole.

Not exact matches

Our black hole's violent meeting with G2 began last year, and as it continues, it should give astronomers a chance to peer inside the galactic center — the neighborhood around the black hole — rather than just simulate the swirling disc of gas and dust surrounding it.

The researchers found that relatively cool accretion discs around young stars, whose inner edges can be several times the size of the Sun, show the same behaviour as the hot, violent accretion discs around planet - sized white dwarfs, city - sized black holes and supermassive black holes as large as the entire Solar system, supporting the universality of accretion physics.

The researchers modeled the resulting accretion disc — an elliptical disc of stellar debris swirling around the black hole — along with its probable speed, radius, and rate of infall, or speed at which material falls onto the black hole.

A black hole's intense gravity also tends to attract gas and dust, which forms an «accretion disc» around it.

It then twists around the black hole to form a brilliant disc, shooting a trail of stardust from its center.

The bright discs of gas around a galaxy's central black hole are thought to be obscured by a torus of dust.

About half of the disrupted star moves in elliptical orbits around the black hole and forms an accretion disc which eventually shines brightly in optical and X-ray wavelengths.

Quasars are the discs of hot gas that form around supermassive black holes at the centre of massive galaxies — they are bigger than Earth's orbit around the sun and hotter than the surface of the sun, generating enough light to be seen across the observable universe.

MATISSE will contribute to several fundamental research areas in astronomy, focusing in particular on the inner regions of discs around young stars where planets are forming, the study of stars at different stages of their lives, and the surroundings of supermassive black holes at the centres of galaxies.

Half the star's mass falls into the black hole, while the other half shoots away at high speed, shocking gas that lies in the halo around the Milky Way's disc until it emits gamma rays.

The other model proposes that the coronas are spread out more diffusely, either as a larger cloud around the black hole, or as a «sandwich» that envelops the surrounding disc of material like slices of bread.
