Scientists Trace First Clue to Understand Violent, Short Duration Flares from ‘Magnetars’

An official statement said that scientists have found the first clue that it comes from a rare type of compact star called a magnetar, which is 13 million light-years away.

These compact stars with the strongest known magnetic fields, only 30 have been found in our Milky Way galaxy so far. They have suffered violent eruptions, but due to their unexpected nature and short duration-only ten percent One second, so it’s still little known. For a long time, scientists have been interested in such short and strong bursts-transient X-ray pulses have energy several times that of the sun, ranging in length from a few milliseconds to a few microseconds.

When massive stars such as supergiants with a total mass between 10 and 25 solar masses collapse, they may form neutron stars. Among neutron stars, a small group of people with the strongest magnetic fields stand out: magnetars.

According to a statement from the Ministry of Science and Technology, a scientific team led by Professor Alberto J. Castro-Tirado of the Institute of Astrophysics of Andalusia (IAA-CSIC) studied an eruption in detail: trying to measure the highest energy of different oscillations or pulses, This is an important part of understanding giant magnetar flares.

Dr. Shashi Bhushan Pandey from the Aryabhatta Institute for Observational Sciences (ARIES) under the Department of Science and Technology worked closely with Professor Castro-Tirado and other team members. This research has been published in the journal Nature. This is the first extragalactic magnetar to be studied in detail.

“Even in an inactive state, the brightness of a magnetar may be thousands of times that of our sun. But in the case of a flash, we studied GRB2001415, which occurred on April 15, 2020, and lasted only approximately The second in tenth, the energy released is equivalent to the energy radiated by our sun in one hundred thousand (100,000) years. Observations revealed multiple pulses. The first pulse appears only about tens of microseconds, which is more than other extreme astrophysics. Transients are much faster,” said lead author Castro Tirado.

It is believed that the explosion of magnetars may be due to the instability of their magnetosphere or a kind of “earthquake” (“starquake”) in their crust, which is a rigid and elastic layer about one kilometer thick. “Regardless of the trigger, a kind of wave is generated in the magnetosphere of the star. These waves, which are well known in the sun, are called Alvin waves, and when they bounce back and forth between the points at the base of the star, their magnetic field lines interact with each other. Works, dissipates energy,” Castro Tirado said.
