Astronomers first saw how the star "eats" the planet-infant

Physicists from the Massachusetts University of Technology using Chandra's X-ray observatory for the first time saw how a young star was absorbing the planet

Astronomers observe the unusual behavior of stars in the constellation Taurus-Aurigo 450 light-years from Earth, which contains the accumulation of thousands of nascent stars. The light in this area decreases once every ten years, then everything returns to normal

In January 2017, scientists record a further drop in the brightness of the star RW Aur A, send him a telescope lens to X-ray "Chandra" hours The analysis of the star's radiation showed that it is much hotter than expected, the surrounding disk density of the star is quite large, and its component was a lot of iron – not as much as in the bowels of the Earth, but about the same as on the Moon.

On the basis of this, the scientists concluded that the last star eclipse was due to a collision with the planet-infant, in whose core there is a large amount Iron

Eclipse RW Aur A – as a result of a plan of failure When this planetary junk entered a star, she created a thick curtain that temporarily obscured the light of the star. "The computer simulation has long predicted that the planets could merge with the structure of a young star, but we have never seen anything like that.Our interpretation of the data is correct, this will be the first time we Let's look directly at a young star devouring the planet or the planet, "says Hans Moritz Guenter, a researcher at the Kavli Institute of Astrophysics and Space Research.

A If the metal is still a lot, astronomers will be able to say for sure that its source is big enough – like a planet slowly absorbed by the star.If the iron lines in the star spectrum become smaller, then the source of the metal is small.

"We spend vast resources to form planets around strangers, of course, it is very important to know how they can be destroyed. The stars, and what factors determine, the planet will be destroyed or will remain in orbit, "says Gunther.
