A team of astronomers and physicists confirmed the existence of clouds Kordylevskogo in which scientists doubted the last 60 years.
Scientists from Hungary have confirmed the presence of two dust clouds in a semi-stable points only 400 thousand kilometers from Earth. For the first time about clouds reported by Polish astronomer Kazimierz Kordylewski in 1961, after whom they were called. A new paper published in the journal Monthly Notices of the Royal Astronomical Society.
The system Earth — Moon, there are five points of stability in which gravitational forces retain the relative position in the object. Two of these so-called Lagrange points, L4 and L5, form an equilateral triangle with the Earth and the Moon move around the Blue planet during the motion of its satellite in its orbit.
L4 and L5 is not entirely stable, because they resent the gravitational influence of the Sun. However, it is considered that these areas may be collected interplanetary dust — at least temporarily. In 1961 Kordylewski watched two nearby dust in cluster L5. Since they are reported repeatedly, but because of the paleness of the clouds they’re hard to register, so many scientists doubt their existence.
In its work, the team of Hungarian scientists led by Gabor Horvath of the University. University Eotvos Lorand modeled clouds Kordylevskogo to assess how they are formed and how they can register. Researchers were interested in their appearance with the help of polarization filters that transmit light with a specific direction of oscillation. Diffused or reflected light always has a smaller polarization, depending on the angle of scattering or reflection.
Then astronomers began searching for dust clouds. Connecting to the lens and the CCD system of filters with linear polarization, they conducted a study of point L5 in the private Observatory were Tears-Balogh in Hungary on the subject of her presence in the clouds Kordylevskogo.
The resulting images showed that polarized light reflected from dust, greatly expanded beyond the field of view of the lens. The observed pattern corresponds to the forecasts of scientists of the same made in the earlier work, and also coincides with other observations of clouds Kordylevskogo conducted 60 years ago. A group of Croat managed to exclude optical artifacts, and other effects. In other words, they confirmed the presence of a dust cloud.
Given the stability points L4 and L5, they are considered potential items in an address space probes, and can also be suitable for transfer stations for missions deeper studies of the Solar system. Also, any suggestions for storing these points of pollutants. Further studies are L4 and L5 and associated clouds Kordylevskogo will focus on the study of their stability and potential danger to equipment and astronauts.
