Astronomers celebrated a new comer earlier this year, after they spotted a pair of neutron stars with a massive and unprecedented mass by invisible signals, which are gravitational waves or "gravitational waves" which are microscopic oscillations of space time caused by extreme disturbances.
Le Monde, in its report published on January 7, gave an example of the severity of these disturbances by the transformation of two neutron stars, each one and a half times larger than the sun but much more intense, when they turn around and then merge.
The newspaper pointed out that astronomy related to gravitational waves is still in its early stages, since only 11 "earthquake" spacecraft have been confirmed since September 2015 through the tools of observing the three gravitational waves, two of which are in the United States and one side in Europe. They are the only ones to detect these small movements, most of which are related to the collision of black holes.
Twelfth tremor
The twelfth tremor was observed on April 25th through the instrument in Louisiana, USA, and its nature was not confirmed until January 6 at the American Astronomical Society conference in Honolulu, after a long analysis, taking into account the signals of the European instrument called the Virgin. . Details were provided to the Journal of Astronomy.
And observed this small deformation in space on April 25, due to the collision of two massive neutron stars, located at a distance of 520 million light years, and in an area of the sky that is too large for the telescopes to cover accurately, and researchers estimate that they occupy approximately 20% of the sky.
The newspaper said that this was the second time that researchers had discovered a collision between a pair of neutron stars, possibly leading to the birth of a black hole, as the first time was on August 17, 2017, and accompanied by a kind of firework, which did not happen this time. Because the body is four times as far away from its predecessor.
New diodes of neutron stars
But the importance of this second pair is different from the first, as it is very heavy, with a mass of 3.4 times the mass of the sun, which is much more than dozens of known binary systems that weigh an average 2.7 times more than our star.
"This discovery indicates the existence of a new binary group of neutron stars that conventional machines had never seen before," says Matteo Parsolia, researcher at the National Center for Scientific Research at the Astrophysical Laboratory at the University of Paris.
The newspaper said that the matter now is to understand how this pair of compact objects formed to the point that a spoonful of its materials weigh a billion tons, and she wondered whether they are simultaneous explosions of two stars. Or is it the result of a massive neutron star entering a binary system, expelling the lighter partner?
The newspaper left the answer to astronomers still questioning the first discoveries of their observatories in 2016 when it identified the presence of double black holes, larger than the holes that we knew until then.
