"It's a kind of dance": Astronomers have revealed the secret of origin of mysterious double planets

To spread: one of the most mysterious and very rare planets are the gas giants of the class "Double hot Jupiter". There are no such in the solar system and their location challenges the theory of planets. Astronomers have revealed the origin, perhaps, the most interesting planets in the universe known as "double hot Jupitors". Scientists believe that their discovery will help to find more of these very rare planets. Group research in The Astrophysical Journal, writes Space. In focus.

These are giant giants with a very high size with Jupiter or more, which rotate at a very close distance from their stars. Thus, the year on these planets lasts less than 24 Earth hours. "Hot Jupitors" rotate around only 1% of stars, that is, very rare planets. But even more rare planets are "double hot Jupitors".

These pairs of planets occur in double star systems, where one planet rotates around each of the twin stars. This is a strange location and scientists have long been trying to decipher it because it challenges the theories of planets. The study authors believe that they have the key to solving this secret. They found that normal, long -term evolution of double systems can naturally lead to the formation of a "hot Jupiter" around each star.

The process studied by astronomers is known as the migration of von Zaipel-Lidov-Kozai. According to this theory, over time, the planet with unusual orbits can be exposed to the gravity of another object, which leads to the fact that they become a "hot Jupiter" near the star. Scientists say that such migration is a kind of dance. In a double system, an additional star can form and deform the orbits of the planets, forcing the planet to migrate inside.

Astronomers believe that planets in double systems can take place a mirror migration process, so both stars are eventually received by a "hot Jupiter". To reach their conclusions, astronomers have created modeling based on planets outside the solar system. As for the search for more "double hot Jupiters", scientists propose to return to double systems that have already found one "hot Jupiter".

The only problem is that these double stars should be at the right distance from each other: not too far and not too close. According to astronomers, their proposed mechanism works best when the stars are at a moderate distance. They should be far from each other so that giant planets can still be formed around each star, but close enough to each other so that two stars can affect each other during the life of the system.
