Black holes turn the planet into dust

Scientists have uncovered yet another mystery of supermassive black holes. How do I find the British and Russian astronomers, mysterious dust belt around them formed from fragments of planets and asteroids.
Article Sergei Nayakshina of the British University of Leicester, Rashid Sunyaev and Sergey Sazonov of the Space Research Institute on the subject published in the journal Monthly Notices of the Royal Astronomical Society. It describes briefly on site of the Royal Astronomical Society.

As is well known to astronomers, in the centers of most galaxies harbor black holes immense weight. However, for some strange reason, so far, they are hard to see through the telescope because of dense dust clouds. Where it came from, it was not entirely clear.

Sergei Nayakshin and his colleagues have suggested that these clouds are similar to the so-called zodiacal cloud in the solar system, which consists of fragments of asteroids colliding with each other. They built a mathematical model to calculate the probability of the same cloud around black holes.

According to calculations by the authors, the belt of asteroids and planets can form around even small stars that are no bigger than the sun (in the classification of astronomers, our star known as a yellow dwarf). When such stars are found with a black hole, they are deprived of all their satellites that hole "drag" to him due to the greater mass. As a result, the black hole forms a belt of large and small planets and asteroids that constantly collide with each other and eventually turn to dust.

For a life that could exist on these planets is not a pleasant prospect. However, as noted Sergey Nayakshin, resulting in a cloud of dust protects the other regions of the galaxy from the powerful radiation, and thus contributes to the life there.

"We suspect that the supermassive black hole in our own galaxy, the Milky Way, has absorbed most of the gas, which could go to the formation of new stars and planets. Opening the origin of dust in the inner regions of the galaxy moves us one step closer to solving the problem of supermassive black holes, "- said the astronomer.
