15 Years Going Steady – Timing the Magnetar 1E 1841-045
We report on a long-term monitoring campaign of 1E 1841−045, the 12-s anomalous X-ray pulsar and magnetar candidate at the center of the supernova remnant Kes73. We have obtained approximately monthly observations of the pulsar with the Rossi X-ray Timing Explorer (RXTE) spanning over two years, during which time 1E 1841−045 is found to be rotating with sufficient stability to derive a phase-co...
متن کاملSpectral comparison of weak short bursts to the persistent X-rays fromthe magnetar 1E 1547.0â‹TM5408 in its 2009 outburst
In 2009 January, the 2.1-s anomalous X-ray pulsar 1E 1547.0−5408 evoked intense burst activity. A follow-up Suzaku observation on January 28 recorded enhanced persistent emission in both soft and hard X-rays. Through a reanalysis of the same Suzaku data, 18 short bursts were identified in the X-ray events recorded by the Hard X-ray Detector (HXD) and the X-ray Imaging Spectrometer (XIS). Their ...
متن کاملTriggers of magnetar outbursts
Bright outbursts from Soft Gamma Repeaters (SGRs) and Anomalous X-ray Pulsars (AXPs) are believed to be caused by instabilities in ultramagnetized neutron stars, powered by a decaying magnetic field. It was originally thought that these outbursts were due to reconnection instabilities in the magnetosphere, reached via slow evolution of magnetic footpoints anchored in the crust. Later models con...
متن کاملMagnetar Spin-Down.
We examine the effects of a relativistic wind on the spin-down of a neutron star and apply our results to the study of soft gamma repeaters (SGRs), which are thought to be neutron stars with magnetic fields greater than 1014 G. We derive a spin-down formula that includes torques from both dipole radiation and episodic or continuous particle winds. We find that if SGR 1806-20 puts out a continuo...
متن کاملSuperfluid signatures in magnetar seismology
We investigate the role of neutron star superfluidity for magnetar oscillations. Using a plane-wave analysis we estimate the effects of a neutron superfluid in the elastic crust region. We demonstrate that the superfluid imprint is likely to be more significant than the effects of the crustal magnetic field. We also consider the region immediately beneath the crust, where superfluid neutrons ar...
