Astronomers have found a "death Star"
American astrologers have identified in the constellation Virgo, the natural analogue of the "death Star" - white dwarf, that eat a large rocky object that moves on its orbit. About the body is of a the remains of planet destroyed by gravitational field of the dwarf.
A unique object was found by a group of American astrophysicists in conjunction with employees from Canada and Australia thanks to the Kepler space telescope. Of course inadvertently in the system of the white dwarf WD 1145 017 was filmed body, orbiting stars, and occasionally obscuring it. The main object of forcing the star to "lose" up to 40% of its luminosity.
Starting from the period of revolution, accounting for about 4 and a half hours, researchers calculated the distance of the object moving along the orbit, to the star: it is approximately 840 thousand km, which Is slightly more than twice the distance from the Earth to the moon. A white dwarf WD 1145 017 placed at a distance of 570 light years from our planet in the constellation of Virgo.
"We were shocked by what they saw. Our eyes were opened that have not seen 1 person, destroyed the solar system", - quotes the author of the study Andrew Vandenberg the journal Nature.
According to Vanderberg, it's the 1st in the history of the case of object detection, moving around the white dwarf. Note that white dwarfs are formed as a result of the burnout of stars with a mass below the Chandrasekhar limit, which amounts to 1.44 solar masses. They represent a heavy small nucleus, containing carbon and hydrogen inside the hydrogen and helium shell. They arise out of the result of the exfoliation of the outer layers from red giant. Our Sun at the final boundary of the evolution will turn into a white dwarf.
