American scientists from Yale University proposed a new explanation for the rarest formation of foreign onions – those who are hot, when surrounding each star in a double system on a giant. The study was published in scientific publications of Physics Magazine (TAJ).
Hot Jupiter – hot air giant, extremely close to their stars – only found in 1% of light. But their double options, in which both stars in the system have such planets are considered rarely rare.
Scientists have conducted a series of computer simulation using spatial tasks of NASA and ESA.
We find that the long -term development of dual systems can naturally lead to the formation of those planets, he explained the head of Malena Rice's research.
The key to clues is the mechanism of Von Tsipel Lidov-Kozai (ZLK)-A fascinating dance, in which planets with orbit gradually move to their stars under the influence of a neighboring optical.
In double systems, the second star can deform the orbit of the planets, forcing them to move inside. We pointed out how this process could be reflected to both stars, Mr. Rice Rice added.
The study also explained the paradox: why the giant planets, will form away from the stars, so close to them.
