Rare pulsar does an even rarer wobble

摘要

A Glitch is not normally something to boast about, but the discovery of one in a rare type of spinning star makes pulsar J1838-0537 special indeed. When Holger Pletsch of the Max Planck Institute for Gravitational Physics in Hanover, Germany, found the pulsar, he and colleagues were excited because it was one of just 30 spotted via their gamma rays. Radio emission gives most pulsars away.
