Breaking news! A star has emitted energy in less than 1 second that the Sun can emit in 100,000 years. See here
Breaking news! A new record has just been set! Recently, a group of researchers and scientists observed how a magnetar released in just one tenth of a second an energy equivalent to that released by the Sun in its 100,000 years. The group of researchers and scientists wanted to more accurately measure the oscillations of a magnetar's brightness in its most violent moments, reports Tech Explorist. And the result they found was beyond expectations.
Magnetars are one of the types of neutron stars and we know very little about them. And we have few pictures of them. They sometimes have strong explosions / eruptions and of course we don't know why they suffer these eruptions. So far there is no clear answer to what the scientists really wanted to study here. That is, it is not known exactly whether there are high-frequency oscillations in magnetars or not (the one measured by scientists and researchers). This has been researched for many years, even decades, but without a clear answer.
Now, however, scientists would have a somewhat good answer. They made measurements on magentar in critical situations and even when they become more "violent". And according to the data there is a very high probability that there are these oscillations in magnetars. Let's see what the main researcher of the study, Alberto J. Castro-Tirado, from IAA-CSIC, says: "Even in an inactive state, magnetars can be 100,000 times brighter than our sun, but in the case of the flash that we have studied - GRB2001415 - the energy that was released is equivalent to that which our sun radiates in 100,000 years."
Also, this "new observation" is not so new. Theoretically, what the magnetar did dates back to 2020.
Víctor Reglero, professor of Astronomy and Astrophysics at the UV, said, "The explosion of the magnetar, which lasted approximately 10th of a second, was discovered on April 15, 2020, amid the pandemic. Since then, we have developed very intense data analysis work since it was a 10 ** 16 Gauss neutron star located in another galaxy. A true cosmic monster. "
Also, from several studies in a row it has become widely accepted that magnetars produce these eruptions due to instabilities in their magnetospheres or a kind of "earthquake" produced in their crust. Researcher Alberto J. Castro-Tirado clarified this: "Regardless of the trigger, a type of wave is created in the star's magnetosphere - the Alfvén - which are well known in the sun, and which interact with each other, dissipating energy. "
In addition, in a paper published on the basis of this study, the stewards stated: "The oscillations observed in the eruption are compatible with the emission caused by the interaction of Alfvén waves. The crust quickly absorbs energy from Alfvén waves. "; "The magnetic reconnection process, and hence the pulses identified in GRB2001415, ends in a few moments, fading 3.5 milliseconds after the initial burst. The volume of the explosion was estimated to be similar to or even more than that of the neutron star itself, based on the examination of the phenomena."
It's good that there is advanced technology, because otherwise, what scientists have now noticed, you may not have been able to observe.
A well-developed AI system from the Image Processing Laboratory (IPL) of the University of Valencia was used to complete this study. Reglero said, "The detection of quasi-periodic oscillations in GRB2001415 was quite a challenge from the point of view of signal analysis. The difficulty lies in the brevity of the signal, whose amplitude rapidly decays and becomes embedded in background noise. And, as it is correlated noise, it is difficult to distinguish its signal."
We wish success to the researchers and scientists who conducted this study, so that they can bring us such important information.
