Astronomers for the first time published a picture of a system consisting of a sunlike star type TYC 8998-760-1 and two giant exoplanets. This was reported in an article published in the journal the Astrophysical Journal Letters.
The researchers directly observed the new planet using a telescope of the VLT (Very Large Telescope) in Chile. Although scientists have got pictures of exoplanets in other mnogoletnih systems and their parent stars vary greatly in characteristics from the Sun.
Found a gas giant with mass 14 times as much as Jupiter and orbits a star at a distance of 160 astronomical units (one astronomical unit is approximately equal to the average distance from the sun to the Earth). For comparison, Pluto is distant from the Sun at a distance of 39 astronomical units. The second planet — TYC 8998-760-1-with — deleted from the parent star at 320 astronomical units. It is six times more massive than Jupiter.
TYC 8998-760-1 was only 16.7 million years ago. According to scientists, the study of this system will help to Refine models of the formation of the Solar system. According to one of the popular ideas, giant planets initially arise at a great distance from the Sun, and then migrate closer. In the future, exoplanets TYC 8998-760-1 will be possible to check for signs of life.
