Scientists have discovered a dead cannibal star that devours its planets in an unusual way

A new study has shown that a white dwarf attracts debris from even the very far reaches of its system.

< p> Scientists from the University of California at Los Angeles were able to see something that had never been observed. A cooling dead star or white dwarf absorbs debris from planets not only from the inner part of the system, but also objects that are very far from the star, according to Phys.

According to theories of the evolution of planetary systems, they die as a result of the death of their star. At the end of its life, a star similar to the Sun grows in size and becomes a red giant, and then loses its outer layers of matter and turns into a white dwarf, which cools down over billions of years.

When a star grows in size, it leads to the destruction of nearby planets, and those that remain, go out of their orbits. The fragments of the planets, along with asteroids, comets and satellites, begin to attract a white dwarf, and in this process it will become overgrown with the resulting substance.

According to scientists, our Sun will also become a white dwarf in 5 billion years. And the same thing will happen to the planets and other objects in our solar system, which is happening to a star called G238-44, 86 light-years away.

But a new study shows that within 100 million years after the transformation of a star into a white dwarf, it can not only absorb nearby material, but also capture very distant objects from regions of space that are similar to our Kuiper belt.

“For the first time, we have witnessed that objects from the inner part of the planetary system and objects from regions of space very far from the star can be attracted by the star at the same time “, – says Ted Johnson from the University of California at Los Angeles.

According to astronomer Beth Klein, who took part in the study, this white dwarf cannibalism provides a unique opportunity to learn what planets were created from when they first formed around the star. After all, almost the entire elemental composition of the planets can be seen on a dead star.

Scientists, based on the analysis of the elements of the atmosphere of a white dwarf, found out that around the star there were the same planets as our Earth, as well as Venus, Mars and Mercury.

Focus already wrote that scientists disproved the theory of planet formation using a meteorite from Mars.
