Neutron stars: Pulsars crash the magnetar party

The discovery of a youthful neutron star with an extreme magnetic field blurs the once clear divide between magnetars and pulsars.

Radio pulsars are rapidly spinning, strongly magnetized neutron stars that produce pulses of X-rays and gamma-rays as well as radio waves. A combination of data from two X-ray satellites recently led to the discovery of a very young pulsar with an unusually high magnetic field, as reported by Eric Gotthelf and collaborators1 in Astrophysical Journal Letters.
