An international team of astronomers, including researchers from the University of Cambridge, United States, found a young planetary system, which can help to understand how our solar system formed and evolved billions of years ago.

Using the tool Gemini Planet Imager (GPI) telescope Gemini South, located in Chile, the researchers identified a bright ring of dust in the form of a disk surrounding the star HD 115600, a little more massive than the Sun and located at a distance of 360 light-years away in the constellation Centauri. This CD is at a distance of 37 to 55 astronomical units (5.5 - 8.2 billion kilometers) from the parent star, that is about the same distance from it, in what is the Kuiper Belt from the sun. The brightness of the disk, which is due to reflected starlight, also consistent with the composition of dust consisting of silicate and ice, which is present in the Kuiper Belt.

The star observed by scientists in a new study, is a member of OB-associations Scorpio - Centaurus, outer space, the conditions which are similar to the conditions in which flows the formation of our sun. Center astronomers observed disk is shifted from the center of the star, which is a strong argument in favor of the presence in the drive of one or more unseen planets astronomers is.

"We like looking at the outer part of the solar system at the time when she was still only just been formed," - said the head of research Thane Currie, an astronomer and a member of the Observatory "Subaru", located in Hawaii, USA.
