Sentences with phrase «hole accretion disc»

«If there are many axion stars in the centres, we expect that some of them collide with the black hole accretion disc,» says Iwazaki.

Not exact matches

The swirls within the wrap remind me greatly of elliptical orbits of planets, the theoretical shape of galaxies, and even the accretion disc of the black hole.

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.

Computer simulations suggest that when two black holes spiral towards each other on a collision course, much of the gas and dust in the spinning accretion disc surrounding each of them is ripped away by the gravity of the other.

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.

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.

Their tendency would be to cluster near the centre of galaxies, making them more likely to pass near the supermassive black holes that sit there and run into the accretion discs of gas that surround them.

Scientists had already suggested that, close to the black hole, the flat accretion disc puffs up into a hot plasma, in which electrons are stripped from their host atoms.

Known as an accretion disc, it is the place where material gradually spirals inwards towards the black hole.

So if astronomers can understand the physics of the matter that is flowing into the black hole, they can use it to test the predictions of general relativity as never before — but only if the movement of the matter in the accretion disc can be completely understood.

Those would cluster near the centre of galaxies, making them more likely to pass through the accretion discs of supermassive black holes there, causing the bursts we detect.

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.
