We report a major outburst from the anomalous X-ray pulsar 1E 2259+586, in which over 80 X-ray bursts were detected in 4 hr using the Rossi X-Ray Timing Explorer. The bursts range in duration from 2 ms to 3 s and have fluences in the 2-10 keV band that range from 3 × 10-11 to 5 × 10-9 ergs cm-2. We simultaneously observed increases of the pulsed and persistent X-ray emission by over an order of magnitude relative to quiescent levels. Both decayed significantly during the course of our 14 ks… Expand
Changes in the X-Ray Emission from the Magnetar Candidate 1E 2259+586 during Its 2002 Outburst
An outburst of more than 80 individual bursts, similar to those seen from Soft Gamma Repeaters (SGRs), was detected from the anomalous X-ray pulsar (AXP) 1E 2259+586 in 2002 June. Coincident withExpand
Anomalous X-ray pulsars: long-term monitoring and soft-gamma repeater like X-ray bursts
Abstract We report on long-term monitoring of anomalous X-ray pulsars (AXPs) using the Rossi X-ray Timing Explorer (RXTE). Using phase-coherent timing, we find a wide variety of behaviors among theExpand
