A radio-quiet neutron star is a neutron star that does not seem to emit radio emissions like most other neutron stars. Most neutron stars are pulsars and emit radio radiation.Quark stars theoretical neutron star-like objects composed of quark matter may be radio quiet according to some theories.More plausibly however radio-quiet neutron stars may simply be pulsars which do not pulse in our direction. As pulsars spin they emit radiation from their magnetic poles.
