A pair of rare and white stars that were collided in about 23 billion years have been discovered by researchers at the University of Warwick. After rapprochement, the dual stars system will explode in 1a supernova. Scientists have long expected that two white dwarf stars are responsible for creating a 1A 1A supernovas type 1A, but this discovery represents the first time that the stars system that goes down to this path is observed.
The bilateral stars system sits about 150 light years from land. It is also incredibly heavy, with a combined mass equal to about 1.56 times from sun. With a very high mass, the white dwarf stars are really estimated to explode, the team says.
“When I first monitored this system with a very high mass on the doorstep of the galaxy, I was immediately excited,” James Monday, PhD. A researcher at the University of Warwick and the leader of the investigation said, In a statement.

A White dwarf Star is mainly the body of a low -mass star that lost its outer layers. This can happen when the star runs out the fuel supplies needed to maintain nuclear fusion reactions that occur in their essence. The rest of it is the heart of raw stars – a white dwarf. Ultimately, the e -mail -ended dwarf stars scientists will start a closer orbit around each other. After that, the two heaviest of the materials will accumulate from the lesser partner. This will be what causes the Supernova event.
Monday added: “With an international team of astronomers, four headquarters at the University of Warwick, we immediately applied this system to some of the largest visual telescopes in the world to determine the exact extent of its inflation.”
Type 1 supernovas Very useful for scientists, because Supernovas tends to explode almost the same amount of energy. The consistent energy measures this scientists to predict shine, or the fundamental brightness of Supernova.
In gloss measurement, scientists can calculate vast distances in the universe. The use of traditional measurements of these distances is not practical, of course, due to the large size of the universe, so scientists use “standard candles” or things with a known essential brightness, as milestones in a “cosmic ruler” of some kind.
Therefore, with this new discovery, scientists have found the type of stars system that creates these beneficial measurement tools. “In the end, we can now, as a community of a few percent of the SUPERNOVAS rate of 1A across milky way Certainly, “Monday said.
Nowadays, the white dwarves shine around each other with a tropical rate more than 14 hours. After a few billion years, the stars will increase. In the end they will move faster, they rotate each other at a rate of about 30 to 40 seconds. After that, the Supernova – which has more than a thousand trillion trillion trillion nuclear bombs.
“This is it [a] In the same statement, Dr. Ingred Pilesouli, assistant professor at Warwick University and the third author, said in the same statement that the stars system seemed relatively close and the causes of Peliseuli, that these types of white dwarf pairs, and otherwise, were supposed to search for the causes of Bilisoli.

“Finding this system is not the end of the story, it is still a survey looking for the predecessor of the type 1A superova and we expect more exciting discoveries in the future.” “Something slowly, we are getting more than a solution to the mystery of the bangs of 1A.”
