We usually know that the greatest psele is a super giant star that explodes at the end of his life, but in some cases the star from the small white dwarf category may explode to the extent that if it was the size of a ground tennis ball, for example, the sun would have been a football size.
These stars arise from corrosion that affects the surface of the middle stars like our sun, as their outer layers are ejaculated in the form of strong stars, and only the center remains in the form of a “white dwarf”, how can a very small dwarf star explode?
When the white dwarf is in orbit with another giant star, that is, they revolve around each other, affected by the attractiveness between them, here the white dwarf withdraws – because of its intense attractiveness – the giant comrade material very quickly.
With the accumulation of the red giant material on his dwarf companion and its rapid collision with its surface, rapid and surprising nuclear reactions begin on the white dwarf, and at some stage the star explodes with the greatest borrowed, we call it “greater bombardment than type 1A”.
Various borrowed
But the Hubble Space Observatory data showed a sub -type of these explosions, which is a rare and less violent type than the Great Rain of Type 1A, and it usually occurs in the white dwarf stars as well, and the name “Great Movement of Type 1 X”, according to an official statement from the Hubble Observatory platform.
The story of this different pselex begins from a distant galaxy called the GC 1309, about 100 million light years from Earth, where scientists were watching a stars explosion that occurred in 2012.
After the explosion, the scientists returned in 2023 to review the pictures of the Hubble space telescope, and they found that the star who exploded was still present and radiant.
This is a short video from NASA, which represents a short, high -resolution tour of the “NGC 1309”, as monitored by the Hubble telescope:
Native candles
Scientists believe that the “1 X” bangs – during their explosion – radiate a light less than the standard hugs by about 5% to 30%, and that the explosion is irregular, as it may be weak from one side of the star and severely on the other side.
This type of bureau provides an opportunity for scientists to achieve a better understanding of the operations of the development of stars, as it explains some of the universal events that were mysterious or inconsistent with the previous models that scientists follow to calculate the power and energy of the great borrowers of this type.
On the other hand, this helped scientists improve the accuracy of cosmic measures (those that calculate the distances to distant galaxies), because the Great Raids of type 1A are used as “normative candles” for measurement, and the reason for the expansion of the accelerated color expansion, which received the Nobel Prize in 2011.
