A great mystery about supernovae finally seems to have been resolved

Computer simulations have confirmed how the most powerful magnetic fields of the universe are formed, solving an enigma that had not been answered for 15 years

A new study has revealed the mechanism that shapes the magnetarsstars with magnetic fields of extraordinary intensity. The key is in the material that, after being expelled in an explosion of Supernova, falls again on the star and triggers a process that scientists have been studying for years.

As they tell us in Nature Astronomy, an international team from the University of Newcastle, the University of Leeds and several French research centers has achieved demonstrate the origin of the most intense magnetic fields we know. The research focuses especially on the so -called low field magnetars, discovered in 2010.

Unraveling stellar magnetism

The return of the expelled material Increase the rotation speed of the starmodifying its internal structure. This turn activates the Tayler-Spruit dine, a mechanism that converts the movement of the star plasma into magnetic fields, generating forces that exceed any comparison with what we know on earth.

In the nearby universe, there is a 3,000 light years star that is about to explode in a visible show from our planet. The magnetic magnetic fields They exceed hundreds of billion times to the groundcausing an intense X -ray emission that distinguishes them from the rest of the star objects.

Dr. Andrei Igoshev, main investigator of the study, has used Advanced numerical simulations To study the magneto-thermal evolution of these stars. In another area of ​​the cosmos, a star that explodes every 80 years is close to its next cycle of activity.

Computer simulations have revealed the internal structure of these magnetic fields, showing that Its intensity is much greater in the nucleus than on the surface. This result gives the reason to a proposed theory 25 years ago, when computers could still not perform such complex calculations.
