About 620 light years from the Earth, giant The robber of the proto-planes Currently devouring 6.6 billion tons of dust and gas per second. Based on recent observations, a relatively new resident Chamaleon constellation It does not stop in the near future – and the situation can become even more intense. But, according to astronomers, this can be quite standard behavior for these space objects.
Planets are usually formed around the star, but this is not always the case. Sometimes a fraudulent planet is formed when it just swims in space. Exactly how these cosmic oddities get their start, remains a question of debate for astronomers.
“The origin of fraudulent planets remains an open question: their objects with the lowest mass formed as stars, or giant planets thrown from their birth systems?” Alex Sholts, astronomer from the University of Saint -Endryus, Great Britain, explained in his statementField
For several months, Sholts and his colleagues used both European Southern Observatory Very large telescope (ESO VLT) and James Webba Space Telescope (JWST) To monitor this fraudulent planet is now classified as Cha 1107-7626. The young object is already 5-10 times more than the mass JupiterAnd surrounded by a spinning disk of gas and dust. Like the gravitational forces that garbage inward, it accumulates together in the process known as accretion.
According to the study of the team recently published in Astrophysical magazine lettersCha 1107-7626, the accretion rate has quickly accelerated. In just a few months, the growth rate of the fraudulent planet increased to about 6.6 billion tons per second, about eight times more than the initial grades of researchers. These measurements are considered the most powerful accretion event ever registered in the planetary mass facility.
“People can think about planets as quiet and stable worlds, but with this discovery we see that the objects of planetary masses, freely floating in space, can be captivating seats,” said Victor Almodros-Abad, co-author of research and astronomer at the National Institute of Astrophysics of Italy.
The data accumulated by the James Webba (JWST) space telescope also show that the CHA 1107-7626 magnetic field is an integral part of the formation process. Surprisingly, this makes him more in common with a typical young star than experts, previously understood.
“The defeat is how the infancy of free planetary objects resembles such stars as The Sun,” said Ray Jayardhan, co-author of training and astronomer at John Hopkins University.
He added that the latest discoveries illustrate as space objects, such as giant proto-planes, are very similar to stars. They both include contract clouds of garbage, surrounding discs and are exposed to various growth episodes.
“Their infancy seems much more violent than we understood,” said Jayardhan.
