VIVAnews -scientists have found a binary system consisting of two stars of ' white dwarf ' or a star at the end of his life. Unique, the two stars are expected to collide with each other and gave birth to a new star.
As is well known, faded the Sun, and more than 90 percent of all stars in the milky way, one time going into the stage of a white dwarf that has a core that Dim, because nuclear fusion reaction is stopped.
Ember is cooled, which currently accounts for about 10 percent of all the stars that exist in our Galaxy, generally have a weight between 40 to 90 percent of the mass of the Sun we have solidified in a ball the size of the planet Earth.
A few of the stars that rotate around each other each other themselves found for. But this is the first pair of stars that rotate and will bump into each other and the formation of new stars.
"The stars are conducted along almost the entire period of his life. When they join, they will be reborn and a second life, "said Mukremin Kilic, an astronomer from the Harvard-Smithsonian Center for Astrophysics, Cambridge, Massachusetts, United States.
Quoted from space, may 12, 2011, the new binary system found the SDSS J010657.39-100003 3 and is located in the constellation Cetus, which is located at a distance of 7800 light years from Earth. They are found in a survey carried out in combination with the MMT Observatory on Mount Hopkins, Arizona, United States.
The binary system is composed of a pair of white dwarf stars. One star in sight and a looks not that its existence is indicated by how he bend in gravitational sees.
Star looks only weighs about 17% of the mass of the Sun, as for other stars with a mass of 43 percent of the Sun. Astronomers believe that the two stars were composed of helium.
The two stars orbiting each other is another white dwarf with a distance of 225 thousand kilometers closer than Earth to the moon. They run on the speed of 1.6 million kilometres per hour and fully run in 39 minutes. So far, they are a few of the most high speed stars ever found.
Since they are spinning in the distance, they do differ from the structure of space and time, produce a ripple road energy, allowing them to rotate wear is getting closer. After that, in the coming year 37 million, the two stars will be bumped.
In a report published in the Official Journal of the Royal Astronomical Society, researchers said, the process of merging white dwarf himself bring the explosion of the supernova. However, it happens only if a join has two star's total mass is 140 percent compared to the Sun.
According to the researchers, the two stars will join does not have sufficient resources to the production of a supernova explosion. But they are big enough to force the atoms of helium in the remains of the merger to light up.
The beginning of nuclear fusion in stars which beru joined make it seem like a regular until the end that he will be cooled and back into a white dwarf.
"Maybe there are many stars in the milky way like this," said Kilic. "Currently we are searching for binary white" Edward else closer to join, and we predict that there is a great opportunity to find, "he said.
