For the first time, scientists measure vibrations in the brightness of a massive neutron star during the eruption


The sun is our very own star in the center of the solar system. Despite being closest to Earth, scientists are still trying to understand the core of the sun, which often creates massive solar winds on our planets. While this is ongoing research, an international group of scientists has attempted to study a neutron star that is formed when a giant star dies in a supernova and its core collapses to form neutrons. First, the group says they were able to measure the fluctuations in brightness in a magnetar – a type of neutron star believed to have an extremely strong magnetic field – during its violent moments.

Surprisingly, the scientists found that the magnetar was released in just a tenth of a second, with energy equivalent to that produced by the sun over 100,000 years. Investigating the fluctuations in brightness of a neutron star is crucial to understanding giant magnetic eruptions. The scientists say their results have negated questions about how magnetars perceive high frequency vibrations.

The study was published in the journal Nature. The work is a collaboration of 41 researchers.

“Even in an inactive state, magnetars can be hundreds of thousands of times brighter than our sun, but in the case of the lightning we studied – the GRB2001415 – the energy released is equal to the energy our sun radiates in you.” A hundred thousand years, “said the lead researcher Alberto J. Castro-Tirado from IAA-CSIC, a Spanish government institute, opposite Nanowerk.

The explosion, which lasted a tenth of a second, was discovered on April 15, 2020 in the middle of the COVID-19 pandemic, according to the study. It added that the flare “was detected by the Atmosphere-Space Interactions Monitor instrument aboard the International Space Station ISS”. Since then, the scientists have been analyzing the data.

Among the neutron stars, magnetars are objects that can contain half a million times the mass of the earth and represent the strongest known magnetic field. So far only 30 of these objects are known.

The study adds: “These extremely high-frequency vibrations in the burst peak are a crucial component that will support our understanding of giant magnetic flares.”
