Anomalous X-ray pulsars (AXPs) are an observational manifestation of
magnetars—young, isolated, highly magnetized
neutron stars. These energetic
X-ray pulsars are characterized by slow rotation periods of ~2–12 seconds and large
magnetic field
A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to ...

The tesla (symbol: T) is the unit of magnetic flux density (also called magnetic B-field strength) in the International System of Units (SI).
One tesla is equal to one weber per square metre. The unit was announced during the General Conference ...

SGR/AXP Online Catalog
(An online catalog of SGR/AXP properties maintained by the pulsar group at McGill University) The identification of AXPs with magnetars was motivated by their similarity to soft gamma repeaters.
