For the first time, a team of astronomers has occupied a clear picture of a white dwarf star that not only exploded once, but twice, as a kind of supernova-a “double dust” that scientists had not yet thought of. Extraordinary observation can revisit our long -standing ideas about how the stars die, suggesting that some stars can explode as a supernovoes without crossing the limits of Chandra Shekhar, at least largely considered necessary for such explosion. Astronomers used a very large telescope music tool to zoom in the rest of the four -century Supernova, which is sitting at Burj Dorado at a distance of 60,000 light years, which has shown evidence of two separate blasts in its construction.
The first visual evidence shows that white dwarf can burst twice without lunar lunar Shekhar’s limit
As researchers reported on July 2 on July 2, the team found a specific “fingerprint” in the debris of SNR 0509-67.5 in the big magelic cloud, whose models predicted. White dwarfs-which is the dead phase of the stars like the sun-usually the type IA supernovas are usually blown away after the stealing of the material from a neighboring star and collided with the limits of Chandra Shekhar.
However, this detection shows that the explosion can be launched in the past. The team says the blast is likely to be two steps, the team is likely to be original, with an initial explosion when the star achieved an unstable layer of hemorrhoids exploded. As a result, a wave of trauma again carried out a second and important explosion.
“This physiological evidence of double description not only helps to solve a longtime mystery that causes these blasts, but also represents a very compulsory evidence for the origin.” Prem Das, University of New South Wales, Team Leader and Author.
Something is happening to type the “standard candles” used to measure the cosmic distances, as they do not fluctuate. But they have long burst into presidency scientists how they burst. Until this discovery, an explosion white dwarf that did not exceed Chandra Shekhar was considered only in theory.
This fresh visual evidence for the double blast model further informs information about our steeller evolution and also informs how we should translate the light from remote sprinkos. More than its scientific implications, the story of the stars dying from its discovery includes a colorful new page – the stars that now appear, will not go slowly in that night but will light the sky twice in the amazing fireworks before disappearing from the universe.
