Jakarta, CNN Indonesia —
Astronomers announce oddities in star white dwarf of similar size to Earth but the rotation is very fast.
The star is named Lamost J024048.51+195226.9 or J0240+1952 which rotates at a speed of once every 25 seconds.
According to researchers, this is the star with the fastest rotation. The speed is 20 percent greater than the findings of other white dwarfs that spin in 29 seconds.
Although the size of the Earth, but according to astronomers the mass of this star 200 thousand times more. Thus, the small, dense object is considered a natural oddity.
Reported Gizmodo, a small star or white dwarf is a relatively cool compact star that is nearing the end of its life. But this star is destroying everything around it in its final years.
A team of astrophysicists from the University of Warwick and the UK’s University of Sheffield have determined the degree of the star’s extreme spin and published it in the Monthly Notice of the Royal Astronomical Society: Letters.
“J0240+1952 will complete several rotations in a short period of time…The rotation is so fast that the white dwarf must have above average mass to remain solid,” said Ingrid Pelisoli, an astrophysicist at the University of Warwick and lead author of the paper.
Rare phenomenon
Researchers have shown that this star is a very rare example of a magnetic vane system. The tiny star pulls gas plasma from a nearby companion star and throws it into space at a speed of about 3,000 kilometers per second, as quoted Indian Express.
J0240+1952’s gravitational pull sucks matter from a nearby star and its magnetic field pushes that material out into space, much like astrophysics. That motion makes J0240+1952 the second star ever discovered to act as a magnetic vane.
