Title:  Pulsars and Magnetars:  facts and possible fiction

 

Abstract:  Anomalous X-ray Pulsars (AXPs) and Soft Gamma-ray Repeaters (SGRs) are relatively young, isolated neutron stars, that are thought to have super-strong ($10^{14} – 10^{15}$ 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 that invokes accretion onto neutron stars with normal magnetic fields.  The accretion takes place along dipole-field lines, while the observed big bursts are due to multipole components of the magnetic field.  I will discuss what it will take to decide between the two pictures.
