Περίληψη :

Anomalous X-ray Pulsars (AXPs) and Soft Gamma-ray Repeaters (SGRs) are relatively young, isolated neutron stars, that are thought to have super-strong ( 1014 – 1015 G ) dipole magnetic fields and even larger internal toroidal magnetic fields. Thus, they were given the name Magnetars. I will examine if this is a fact or possible fiction. I will present an alternative picture and I will discuss what it will take to decide between the two pictures.
