Chandra Observations of the Anomalous X-ray Pulsar 4u 0142+61
We present X-ray imaging, timing, and phase resolved spectroscopy of the anomalous X-ray pulsar 4U 0142+61 using the Chandra X-ray Observatory (CXO). The spectrum is well described by a power law plus blackbody model with Γ = 3.35(2), kTBB= 0.458(3) keV, and NH= 0.91(2) × 10 22 cm; we find no significant evidence for spectral features (0.5− 7.0 keV). Time resolved X-ray spectroscopy shows evide...
متن کاملX-ray and Infrared Enhancement of Anomalous X-ray Pulsar
The long-term ( 1.5 yr) X-ray enhancement and the accompanying infrared enhancement light curves of the anomalous X-ray pulsar 1E 2259+586 following the major bursting epoch can be accounted for by the relaxation of a fallback disk that has been pushed back by a gamma-ray flare. The required burst energy estimated from the results of our model fits is low enough for such a burst to have remaine...
متن کاملImaging X-ray, Optical, and Infrared Observations of the Transient Anomalous X-ray Pulsar Xte
We report X-ray imaging, timing, and spectral studies of XTE J1810−197, a 5.54 s pulsar discovered by Ibrahim et al. (2003) in recent RXTE observations. In a set of short exposures with the High Resolution Camera on-board the Chandra X-ray Observatory we detect a strongly modulated signal (55±4% pulsed fraction) with the expected period located at (J2000) 180951.08, −194351. 7, with a uncertain...
متن کاملRXTE Monitoring of Anomalous X-ray Pulsar 4U 0142+61: Long-Term Variability
We report on 10 years of monitoring of the 8.7-s Anomalous X-ray Pulsar 4U 0142+61 using the Rossi X-Ray Timing Explorer (RXTE). This pulsar exhibited stable rotation from 2000 March until 2006 February: the RMS phase residual for a spin-down model which includes ν, ν̇, and ν̈ is 2.3%. We report a possible phase-coherent timing solution valid over a 10-yr span extending back to March 1996. A glit...
