Astronomers have discovered a rare species of star

ستاره شناسان گونه نادری از ستاره‌ها را کشف کردند

Australian astronomers have discovered another new type of star called the “magnetorotational hypernova”, which is formed by an explosion about ten times the size of a normal supernova and produces heavy elements such as zinc and uranium.

For a detailed explanation of this type of star must go back in time Let’s go back. In the early years of the universe, about 13 billion years ago, there was a giant star made of hydrogen and helium.

The star rotated very fast and had a very strong magnetic field. The star was running low on fuel until it ran out of fuel and was no longer a star. The star’s last breath was so violent that it collapsed and then exploded. Such a star is a spinning supernova. These stars explode ten times larger than a typical supernova.

A recent study is the only clue we have about the existence of these stars. In this study, researchers found that a star called J2003-1142 contained very small amounts of iron. The presence of iron inside the star indicates that it originated from the explosion of a primitive star. There were also amounts of different elements in the star that were not normally seen after the initial stars exploded.

Researchers have calculated that the star J2003-1142 formed from a chemical soup 13 billion years ago, which could be a remnant of this type of meteorite. This star is 7,500 light-years away. With such a small distance from us we can consider it a cosmic neighbor.

Researchers at the Australian National University have discovered this object among the 600 million objects found in the SkyMapper search of the Siding Spring Observatory. By studying the chemical composition inside the star, they were able to obtain the characteristics of its previous star. The presence of large amounts of nitrogen, zinc and uranium inside the star was very strange.

In the past, scientists believed that heavier elements formed when neutron stars collided with each other. But now it has become clear that the collision of stars alone is not enough to justify all the heavy elements in the universe, and there are other possibilities.
