It is the fastest spinning neutron star found to date, breaking the 24-year record held by the 642-hertz pulsar B1937+21. The difficulty in detecting this pulsar, because of its very low flux density and high eclipse fraction (\u223c40% of the orbit), suggests that even faster spinning neutron stars exist. If the pulsar has a mass less than twice the mass of the Sun, then its radius must be constrained by the spin rate to be &lt;16 kilometers. The short period of this pulsar also constrains models that suggest that gravitational radiation, through an\n                    <jats:italic>r<\/jats:italic>\n                    -mode (Rossby wave) instability, limits the maximum spin frequency of neutron stars.\n                  <\/jats:p>","DOI":"10.1126\/science.1123430","type":"journal-article","created":{"date-parts":[[2006,1,12]],"date-time":"2006-01-12T21:24:45Z","timestamp":1137101085000},"page":"1901-1904","source":"Crossref","is-referenced-by-count":699,"title":["A Radio Pulsar Spinning at 716 Hz"],"prefix":"10.1126","volume":"311","author":[{"given":"Jason W.
