Rogue Magnetar ignores known stars born

A cosmic dynamic chamber with a magnetic field that is stronger than the Earth is challenging astronomers’ understanding of how the most extreme objects in the universe are formed. Magnets travel through our galaxy from an unknown birthplace, making scientists’ origins unusual.

NASA’s Hubble Space Telescope has been tracking for a decade, and the object is designated SGR 0501+4516, suggesting that it may not have been born in violent supernova explosions that often produce these supermagnetic neutron stars.

“Magnets are neutrons of neutrons – neutrons that are entirely composed of neutrons. What makes magnets unique is their extreme magnetic fields.” Ashley Chrimes, an exploration author of Astronomy and Astrophysics and Researcher of the European Space Company, published on April 15.

These excellent remnants have almost comic-like power. If a person is half a distance away from the moon, it will immediately delete every credit card on the earth. In a closer range (about 600 miles), the magnet functions like a science fiction death ray that tear atoms in the human body apart.

Originally discovered in 2008, when NASA’s Swift Observatory detected a strong gamma-ray flash that appeared to be associated with nearby Supernova residue HB9. This comparison seems to confirm the standard theory of magnet formation when a large star explodes.

But Hubble’s delicate sensitivity, coupled with the precise star mapping data from the European Space Agency’s Gaia spacecraft, reveals that magnetism is actually traveling on trajectories that cannot originate from this supernova residue or any other known star explosion field.

“All of these movements we measure are smaller than a single pixel of the Hubble image,” said Joe Lyman, a co-researcher at Warwick University. “Being able to perform such measurements strongly does prove the long-term stability of the Hubble.”

The discovery proposes alternative formation scenarios for SGR 0501+4516, such as the merger of two low-mass neutron stars or the process of hyperplasia-induced collapse, in which white dwarfs draw too much material from their companions.

“Usually, this situation leads to the ignition of the nuclear reaction, and the white dwarf explodes, but nothing is left behind. However, in theory, under certain conditions, the white dwarf can collapse into neutron stars. We think that might be the way SGR 0501 was born,” explains Radboud University and warwick and warwick of warwick of Sgr 0501.

These findings may reveal one of the recent difficulties in astronomy: fast radio bursts – radio waves that last only milliseconds. Some of these bursts come from stars that are billions of years old enough to create supernova stars.

“Magnetic birth rate and formation scenarios are one of the most pressing issues in high-energy astrophysics, affecting many of the most powerful transient events in the universe,” said Nanda Rea of ​​the Institute of Space Science in Barcelona.

Researchers have planned other Hubble observations to study other magnets in our galaxy, which has the potential to reveal whether SGR 0501+4516 is indeed unique or a completely new understanding of the existence of these cosmic extremes.
