Astronomers have discovered a magnetic star that emits the same amount of energy generated by the sun in 100,000 years in less than a second.

Observations of this phenomenon have shown that the size of the flare is more or less the same as that of the star.
A team of Spanish researchers recently published Study In Nature magazine, they say, they recorded in detail the “eruption” of a magnetic star. 3.5 milliseconds Like the energy that the sun produces over 100,000 years.
A small group of neutron stars (objects half a million times heavier than Earth with a diameter of 20 km) with a very intense magnetic field stand alone: Magnets.
So far, only 30 of these bizarre cosmic objects have been discovered, characterized by violent eruptions that are less well known due to their unpredictability and their short duration.
However, astronomers at the Andalusian Institute of Astrophysics (IAA) were able to measure different oscillations (or pulses) that occur at the highest energy moments of a magnet. These oscillations are an important component in understanding the massive explosions of energy known as magnets.
“Even when inactive, magnets are 100,000 times brighter than our sun”, Explained Alberto Castro-Troto, IAA researcher and principal author of the study. “In the case of the flash we studied, GRB200415, which occurred on April 15, 2020, lasted only one tenth of a second. 100,000 yearsHe added.
Observations of this phenomenon were made by the ASIM instrument at the International Space Station, which was able to estimate that the size of the fluorine was similar to or greater than that of a neutron star.
The cause of these extreme cosmic events is not known for sure, but researchers believe that the instability in the magnetic field of magnetic fields may be to blame.Earthquakes“It resulted in its bark.
Castro-Troto noted that “this explosion provided an important element in understanding how magnetic stresses are formed in and around a neutron star,” and that continuous observation of magnets in nearby galaxies will help to understand this phenomenon and to further learn about faster radio explosions. One of the most intriguing phenomena in astronomy“.
