In a First, Scientists Measure Oscillations in the Brightness of a Massive Neutron Star During Eruption

The sun is our own star placed in the middle of the solar system. Even though it became the closest star to Earth, scientists were still trying to understand the sun’s core that often triggered a large sun breeze to our planet. Meanwhile is ongoing research, a group of international scientists has tried to study neutron stars, which are made when a giant star dies in supernova and the essence collapses, forms neutrons. In the first one, the group said it was able to measure oscillations in brightness in magnetar – a kind of neutron star which is believed to have a very strong magnetic field – during the hard moment.
Strangely, scientists found magnetar releasing just a tenth of a second, with energy equivalent to those produced by the Sun in 100,000 years. Their study of oscillation in the brightness of the neutron star is very important to understand the giant magnetar eruption. Scientists say their findings have placed questions related to whether magnetar sees high frequency oscillations.
This study has been published in natural journals. Work is collaboration of 41 researchers.
“Even in an inactive state, magnetar can be a hundred thousand times more radiant than our Sun, but in the case of the flash that we have learned – the energy released is equivalent to what is emitted by our Sun in one thousand years,” lead researcher Alberto J . Castro-Tirado, from Iaa-Csic, a Spanish government institution, told Nanowerk.
The explosion, which lasted for a tenth of a second, was found on April 15, 2020, in the middle of the Covid-19 pandemic, according to research. It added that the flare “was detected by the interaction of atmospheric space interactions on the international space station.” Since then, scientists have analyzed data.
Among the neutron stars, magnetar is an object that can contain half a million times the mass of the earth and is the most intense magnetic field that is known. Only 30 of these objects are known so far.
