Real life ‘Death Star’ continues to destroy the alien world
#Cosmoread: Real Life “Death Star” that astronomers recently shattered a planet orbiting objects caught in the act of destroying continues, researchers say.
This finding how dead stars rip apart their planetary systems could highlight – a phenomenon that the Earth’s solar system billions of years from now maybe, the scientists added.
Such a dwarf planet, moon, asteroid or large as a small planetary body – Recently, a dead star, astronomers detected a planetesimal tearing. Dead star is a white WD 1,145 + 017, which is 570 light years from Earth in the constellation Virgo is known as the dwarf is contained.
White dwarfs super dense, the dead cores of stars ‘dead star’ Earth-sized stars that exhausted their fuel and slough off their outer layers are left behind. Most stars, including the sun, white dwarfs will be one day.
“Our sun is a red giant star to become a day out will balloon, Mercury and Venus and perhaps Earth, wiping out before it becomes a white dwarf,” said study lead author Boris Gansicke, at the University of Warwick in England said astronomer. “Seeing this white dwarf, like the future of the solar system we might get a look at.”
More than twice the distance of the Moon from Earth – NASA’s planet-hunting Kepler spacecraft using the previous research about 520,000 miles (837000 kilometers) away, a planetesimal Transiting, or overcome the white dwarf ‘dead star’. Kepler also comet like object trailing a tail of dust, as well as some additional part orbiting white dwarf about the same distance, and the white dwarf surrounded by a shroud of dust discovered.
Scientists had previously estimated that the amount of material in the white dwarf ‘dead star’ circling 590 miles wide (950 km) dwarf planet Ceres, the asteroid belt between Jupiter Tue and lies by the biggest object that was about equal. He suggested that this white dwarf planets body after spiraled around the dead star was ripping apart, and within about a million years totally rock will be destroyed.
Now Gansicke and his colleagues think that this white dwarf system has evolved rapidly since its discovery just months.
“Not that we can see such dramatic changes on human timescales exciting and unpredictable,” Gansicke Space.com reported.
Astronomers around the rocks and dust of the past work of the system revealed the white dwarf in about seven months, used the telescope to observe the Thai national.
Instead of just a single body around the white dwarf trace evidence, “we have identified six, but there are clearly more – it’s 10, maybe 15, maybe,” Gansicke said.
Planetesimal bodies as seen in previous research about the distances are orbiting dead stars and white dwarf the size of each are two to four times. The researchers say that these large bodies, are not solid rock, but instead very little gas and dust scattering rocks that are now flowing from giant wind.
“The average amount of light blocked by the white dwarf material around 1 percent, or 10 to 11 percent or a fraction of one percent has gone up,” Gansicke said. “We know that many more pieces break apart as a planetesimal explain.”
Gansicke and his colleagues plan to further research on the white dwarf system.
“We can see how things develop over time,” Gansicke said. “How does a planetesimal disruption of work? How long does the whole thing, we all disappear in one or two years might be able to see is how the disk of dust around the star develops? How the metal content would change the white dwarf? ”
In the future, researchers also could hunt elsewhere for similar white dwarf systems. “Maybe we can get one or two or 10,” Gansicke said. . “We have a sample of these systems, we can see the differences between them and the common properties, as a whole, about the process of planetesimal dissolution advance our knowledge of how it works in science – a piece of a puzzle ‘ve got, and now we want to get more information. “
