Assertion: pulsar's spin rate | /r/HasProperty | close to theoretical limit for a pulsar
Facets:
value: for a pulsar
type: OTHER

text: These spin rates are close to the theoretical limit for a pulsar because a neutron star rotating only about four times faster would fly apart as a result of “centrifugal force” at its equator, notwithstanding a gravitational pull so strong that the star’s escape velocity is about half the speed of light.
