The international group of astronomers has discovered a giant exoplanet, which is about ten times greater than Jupiter. It is hidden in the pre-structure disk, a cloud of gas, dust and ice, which surrounds the young MP mus. This disk was previously considered a fully smooth and lacking planet formation of the planet. The work was published in the Nature Astronomy magazine.
The hidden planet was found with two powerful astronomical instruments, the combination of the data of the GAIA Satellite Observatory of the Chilean Alma Radio Station and the European Space Agency. This is the first time that Gaia has been able to discover the planet inside the pre-pattern disk.
In the past, observations have shown that several hundred lights from the country are surrounded by a homogeneous cloud without typical cracks or rings. Such structures usually testify to the presence of the formed planets that "cut" the empties on the disk. The lack of these signs surprised scientists. The star is young, only 7-10 million years old, and at this age, most disks already show traces of planet formation.
The turning point occurred after scientists made double observations with longer radio channels. This allowed them to look deeper into the disk and see the previously hidden structure, inner cavity and two external cracks. Almost at the same time, another researcher noted that the star is slightly "hesitated", a delicate but measurable movement that can occur by the strength of the gravity of the large body in the orbit.
By combining Alma and Gaia data, astronomers came to the conclusion that the disk really hidden a huge gas planet. Computer modeling has shown that such a celestial body can explain the strange movement of the star at the same time as the pre-structural disk.
Alma and Future Telescopes, such as the new NGVLA system, allow us to look deeper into pre-structural disks and help us better understand how planets, including our country, said the study head of the Cambridge University. Alvaro Ribace.
