The existence of a Ninth planet is a theoretical celestial body on the outskirts of the Solar system, causing a lot of debate in the scientific world.
Can it be a miniature black hole? Astrophysics from the USA figured out how it is possible to learn with the help of construction survey telescope LSST. An article describing the work was accepted for publication Astrophysical Journal Letters, writes “Science.news”.
“If small celestial bodies fall into the neighborhood of a black hole, they begin to melt under the action of heat, which produces the gas falling into the event horizon. After that they begin to break the attraction of the black hole, resulting in a characteristic flash of light”, — said one of the authors, Harvard Professor Abraham Loeb.
Almost five years ago two American planetary scientist, Konstantin Batygin and Michael brown, said that he found the first traces of the existence of the mysterious “planet x”. So scientists call the hypothetical ninth planet in the Solar system, which is at a distance of at least 100 billion km from the Sun and is similar in size to Neptune or Uranus.
While scientists have not found her — the researchers were able only to narrow the zone where it can be, and to find new hints of its existence. These failures have led many astronomers to doubt the hypothesis. Other planetary scientists have begun to look for alternative options of how this can look like “planet x” and where it can be.
For example, some astrophysicists now admit that “planet x” might actually be not a gas giant, a large earth-like planet or a”guest” from another star system, and much more exotic object — the so-called primary black hole.
It is a miniature analogue of the ordinary and supermassive black holes, which have mass comparable to stars and galaxies, and planets. As suggested by cosmologists, such black holes could appear in the first moments of the Universe due to the fact that the matter was unevenly distributed across its space. The largest of them could survive to the present day — though they gradually decrease because of Hawking radiation.
To find such objects, according to Professor Loeb, is even more difficult than the classic “planet x”. This is due to the fact that these black holes, in contrast to the cold and invisible planets, by themselves, do not produce any radiation.
Harvard astrophysicists have found that, nevertheless, the most sensitive telescopes on Earth can see the primary a black hole. This is the conclusion of astronomers came, drawing attention to the situation in that part of the Solar system, where it is suspected that “planet x” or a primordial black hole.
As noted by scholars, they will be at the point where the Sun’s gravity weakens so that the primary a black hole the size of a planet will constantly attract from the surrounding space accumulation of matter, including fragments of asteroids and cometsthat filled the outskirts of the Solar system.
As a result, according to calculations of scientists, due to the activity of the black hole will almost always occur miniature flash light. They can appear after the attraction of the black hole will tear apart objects with diameters from a few centimeters to several hundred meters. Existing ground-based telescopes, these flashes are barely noticeable, but they will be able to see construction of the LSST Observatory, which is located at the edge of the Atacama desert in Chile.
“The LSST Observatory extremely wide field of view, so it will be twice a week to take pictures of the entire night sky. This is very important, given that we don’t know exactly where the “planet x”. In addition, its high sensitivity will allow us to find traces of flashes, which produce even the smallest objects approaching a black hole”, continues Loeb.
If the calculations of the theorists are correct, LSST can find traces of the existence of a black hole in the first three years of operation, provided that the mass is comparable to Jupiter or significantly less. Otherwise, astronomers prove that such objects in the Solar system does not exist, and will also help theorists to impose further restrictions on the permissible mass of the primary black holes. It is important to study how the expansion of the Universe.
