The sun turns formerly a month and the Earth formerly a day, but a white dwarf star light- times down spins every 25 seconds, beating the old titlist by five seconds. That makes it the swift- spinning star of any kind ever seen — unless you consider similar fantastic objects as neutron stars and black holes, some of which spin indeed briskly, to be stars (SN3/13/07).
About as small as Earth but roughly as massive as the sun, a white dwarf is extremely thick. The star’s face graveness is so great that if you dropped a pebble from a height of a many bases, it would smash into the face at thousands of country miles per hour. The typical white dwarf takes hours or days to spin.
The fast-spinning white dwarf, named LAMOST J0240 1952 and located in the constellation Aries, got in a whirl because of its ongoing affair with a red dwarf star that revolves around it. Just as falling water makes a waterwheel turn, so gas falling from the red companion star made the white dwarf rotation.
The discovery passed the night of August 7, when astronomer Ingrid Pelisoli of the University of Warwick in Coventry, England, and her associates detected a periodic blip of light from the dim brace. The blip repeated every24.93 seconds, revealing the white dwarf star’s record- breaking gyration period, the experimenters report August 26 atarXiv.org.
The star’s only known rival is an indeed briskly- spinning object in route with the blue star HD 49798. But that rapid-fire rotator’s nature is unclear, with some recent studies saying it’s probably a neutron star, not a white dwarf.
