Abstract

The discovery of an ultra-long period neutron star, emitting unusual radio signals is rewriting our understanding of these unique star systems. The source has been found to reside in a neutron star graveyard and yet still produce radio emission (zombie stars!). It exhibits highly unusual and chaotic pulse shapes quite unlike anything seen in known neutron stars.
