In the universe, the remains of the dead star called neutron stars, and these stars are gaining very strong magnetic fields when the issue is removed during their explosive supernova deaths towards them. Scientists say that the discovery of this dynamo -like mechanism can solve the mystery of the so -called “low field magnetic”.
Magnet We are Neutron stars With the most powerful magnetic fields in the universe, hundreds of trillion times are stronger than the magnetic cover on Earth.
Low field magnetsIt was first discovered in 2010, a wonderful, similar residue with magnetic fields ranging from 10 to 100 times of “classic” magnetic. Their origins were a mystery – so far.
The team behind the new research performed advanced digital simulations for the model of the magnetic and thermal development of the neutron stars.
This revealed a dynamo -like process that can allow the neutron star to develop a weaker magnetic field on its surface, which appears around the typical magnetic.
This process includes materials from Supernova that falls inside during “”Proto Noton star“The stage of the development of these stellar remains. The result is known as Tayler-SPRUIT DYNAMO.
“This mechanism was proposed in theory for nearly a quarter of a century, but it was not recently cloned using computer simulation,” Andrei Igoshv, leader of the research team and scientist at the College of Mathematics, Statistics and Physics at Newcastle University, He said in a statement.
The birth of “dead stars” is complex
Nitron stars are created when stars are saved more than 10 times the sun block that uses fuel supplies used for Nuclear fusion In the core.
This matter results in the stars, which is more than 1.4 times the mass of the sun (the so -called Chandrasekhar limit), Collapse under its own attractiveness.
This sends shock waves rising out to the upper layer of the star, which led to a wonderful huge explosion that explodes these layers and most of the massive star mass. This explosion is referred to as the name Core-COLLAPSE Supernova.

This leaves the nucleus, a Proto Noton star, in the process of becoming excellent residue at the level of 12 miles (20 km) is very dense, if it is brought to the ground, then a teaspoon of its component issue is 10 million tons.
The rapid collapse of this star core has other consequences, too. Like an ice skymate draws between their arms to increase the speed It reaches 700 times per second.
In addition, the basic collapse forces the magnetic field lines together, which increases the strength of the magnetic fields of dead stars.
This leaves very dense stars, rotating quickly, surrounded by a shell of materials.
However, this substance can eventually return to the point of origin, causing the neutron star to become more extreme and unusual.

“Neutron stars are born in supernova explosions,” said Egochayev. “Most of the external layers of the huge star are removed during the super separators, but some materials are declining, which causes the neutron star to rotate faster.”
Igoshev has explained that previous research has shown that this process plays a very important role in forming a magnetic field via Tayler-Spit Dynamo.
The Tayler-SPRUIIT is believed to transform the angular momentum of the plasma Magnetic fields within the star of the neutron. This is similar to how to convert mechanical dynamics on the ground into kinetic energy into electrical energy.
“The magnetic field, which is formed through this mechanism, is very complicated with an internal field inside the star, which is much stronger than the external field,” said Egochayev.

Igoshev now plans to create a new research group at Newcastle University to continue to investigate the strong, complex and mysterious magnetic fields of the neutron stars.
The team’s research was published on February 4 in the magazine Nature astronomy.
