1307.0586 (J. I. Katz)

Antiglitch Inconsistent With Magnetar Model of AXP    [PDF]

J. I. Katz
The recently observed antiglitch of AXP 1E 2259+586 is inconsistent with magnetar models, but may be explained as the consequence of sudden accretion of retrograde matter or "propeller" interaction with surrounding matter. AXP/SGR are explained as single neutron stars accompanied by fallback matter from their natal supernovae. Their phenomenology may be partly accretional and partly the result of dissipation of magnetic energy.
