At its equator it is spinning at approximately 24% of the speed of light, or
over 70,000 km per second.Sept 9, 2017 | H********g

发帖数: 43926 | 5 有意思：
Current theories of neutron star structure and evolution predict that
pulsars would break apart if they spun at a rate of ~1500 rotations per
second or more, and that at a rate of above about 1000 rotations per second
they would lose energy by gravitational radiation faster than the accretion
process would speed them up. |
