Abstract

Magnetars are radio stars Anomalous X-ray pulsars (AXPs) are slowly rotating neutron stars with very bright and variable X-ray emission. They are believed to be magnetars — powered by strong magnetic fields — but unlike 'normal' pulsars, never seem to have pulsed radio emissions. Camilo et al. report that the anomalous X-ray pulsar XTE J1810-197 does in fact emit radio pulses at every rotation. This means that magnetars can be radio pulsars, and there is no need for alternative models to explain accretion without radio pulse production.
