PSR J1748−2446ad is the fastest-spinning pulsar known, at 716 Hz (times per second), [2] or 42,960 revolutions per minute.This pulsar was discovered by Jason W. T. Hessels of McGill University on November 10, 2004, and confirmed on January 8, 2005.
The white dwarf star completes a full rotation once every 25 seconds.

XTE J1739−285 is a neutron star, [2] in the constellation Ophiuchus, situated approximately 39,000 light-years from Earth. It was first observed on 19 October 1999 by NASA's Rossi X-ray Timing Explorer satellite. It had previously been claimed that XTE J1739−285 was the fastest-spinning celestial body yet known, with a frequency of 1122 Hz. [3]
Could it be used to detect the elusive vacuum friction?
2. The massive star explodes, leaving a pulsar that eventually slows down, turns off, and becomes a cooling neutron star. 3. The Sun-like star eventually expands, spilling material on to the neutron star. This "accretion" speeds up the neutron star's spin. 4. Accretion ends, the neutron star is "recycled" into a millisecond pulsar.
The star, growing and accreting material from the surrounding disk, is about 10 to 20 times more massive than the sun and perhaps 10,000 times more luminous. In a first, a newborn star's spinning ...
The fastest-spinning neutron star known is PSR J1748-2446ad, rotating at a rate of 716 times per second [17] [18] or 43,000 revolutions per minute, giving a linear (tangential) speed at the surface on the order of 0.24c (i.e., nearly a quarter the speed of light).
