Astronomers have discovered a new type of star explosion called a magnetic rotating supernova

This star is called SMSS J200322.54-114203.3, It contains more elements, such as zinc, uranium, europium, and potentially gold and other stars of the same age. Researchers say that neutron star mergers are a recognized source of materials needed to forge these types of metals, but they are not sufficient to explain the existence of these elements. Astronomers calculated that only the violent collapse of a very early star, amplified by rapid rotation and the presence of a strong magnetic field, could explain the extra neutrons needed.

Researcher Dr. Simon Murphy said that the chemical fingerprint of a star can tell scientists a lot about its age and the environment in which it was born. He said that the star’s atmosphere lacks heavy elements, which tells us that the star is very old, but its content of heavy elements such as zinc, uranium and europium is very strange. Murphy said that this fingerprint is an indication that the star was produced by gas enriched after the explosion of a very massive, highly magnetized, and rapidly rotating star.

Murphy believes that this explosion is more powerful than a supernova, and the research team calls it a magnetic rotating supernova. He pointed out that this is the first time astronomers have seen the chemical fingerprints of a supernova explosion. He hopes that this discovery will prompt people to carry out new theoretical work to understand this type of powerful explosion. The iron and hydrogen of the star is about 3000 times lower than that of the sun, which is very rare. Astronomers call it an extremely metal-poor star. Although its metal content is less than expected, it contains much more heavy elements than expected, which makes it even rarer.
