The astronomers found a black hole that turned so fast.



Black holes occur when a great star dies and collapses with enough gravity, when he can escape from nothing that is not even the light.

Black holes can absorb and grow the surrounding mass – they can eventually turn into super-mass black holes in the center of the galaxies.

An Indian astronomers team now believes they have found a black hole rotating at a speed close to their maximum speed.

They first noticed this from X-rays taken by the first dedicated astronomical satellite named AstroSat in India.

X-rays came from a binary star system called 4U 1630-47, which contained a black hole, about 10 times the mass of our sun. As gas, dust and other substances were absorbed by the spinning black hole, the research team was turning fast enough to absorb the entire area around it.

Black As the black holes form, the mass and the rotational speed are two features that characterize them, the main researcher of the Soft X-ray Telescope (SXT) from the Sudip Bhattacharyya and Astrosat from TIFR, the Hindustan Times & # 39; ;

Black Mass can be more easily measured because it has a long-range effect due to gravity due to the formation of a black hole. Black

According to Einstein's relativity theory, a rapidly turning black hole allows the space to rotate itself.

This effect, combined with the gas towards the black hole, can produce a rotating, tightly-wrapped vertical magnetic field tower that cuts off a large portion of the gas away from the immediate environment of an energetic, high-speed glade black hole.

And the team believes that this special black hole turns as fast as possible.

There are only five black holes that accurately measure high rotation rates, including the black hole discovered by AstroSat.

This black hole is one of only 20 people identified in the Milky Way galaxy, even if you don't take into account the spinning rates.

The measurements, especially the spinning speed, are very difficult to perform and can only be done with high-quality X-ray observations of the binary star system in which the black hole is a gobbling material from the accompanying star. The lead author, Mayukh Pahari, said.

A joint effort between the United States and India was accepted for publication. Journal of Astrophysics.
