Astronomers, for the first time, a star exploded twice and witnessed a dramatic end.
In a published study in one Astronomy of nature, Researchers analyzed SNR 0509-67.5 SNR 0509-67.5 centuries-old reservoirs, and found the first visual evidence of a star “bilateral explosion” with a very large telescope of the Southern Observatory.
Most Supernova is the result of an explosive result of mass stars when the nuclear fuel is exhausted. Others come from white dwarfs, and our sun remained in motionless nuclei who left after small stars.
“Blasts of white dwarfs play a very important role in astronomy,” A doctor student at the University of New South Wales, Australia, Australia and a research co-author, a statement. “Again, despite their importance, the long-term puzzle of the exact mechanism that triggers the explosions remains unresolved.”
White dwarves can call a type of astronomers a type of astronomers when a star system shares with another star. This supernova occurs only in binary star systems, white dwarf as a selfish sister, steals the material from his wife from his wife until a settled mass grows. At the moment, the White Dwarf is unstable, resulting in a mass explosion.
Recent studies pointed out that this could not be the whole story. Astronomers intended to be at least one type of Supernova, in fact, the result of two explosions. In this scenario, a white dwarf is a helium rich material stolen from his partner star. He sends a shock wave through the helium unstable and inactive stars. This is another explosion that starts in the nucleus of the star, as a result of a supernova.
Astronomers predicted a unique fingerprint in a supernova’s remnants of two explosions, and a finger that appears after the initial explosion. So far, the astronomers did not have visual evidence of this fingerprint. However, they were finally learned by studying the Supernova SNR 0509-67.5, by observing the very large telescope of the European Southern Observatory (Muse) with a multi-section spectroscopic researcher (MUS). The analysis allowed researchers to determine the distribution of various chemical elements that appear in the form of different colors. They were organized in two concentric shells and saw different sheets of calcium. These two layers provide the evidence that the two blasts live.
The results were “Ivo Seitenzahl, a double explosion in nature,” Ivo Seitenzahl, where the famous chandrasekhar of the white dwarfs reached the massacre, he said he was a researcher at the Heidelberg Institute.
In addition to being extremely cool, IA Supernova is the key to expanding the universe and study dark energy, because their consistent behavior and predictable brightness can help measure distances in the space of astronomers.
And as a bonus, visually surprising. “This material proof of this material detention has only contributes to a secrecy for a long time, and at the same time offers a visual performance,” he said.
