Rotation-Powered Pulsars and Magnetars
I will review the latest developments in understanding the high-energy emission of rotation-powered pulsars and magnetically-powered Anomalous X-ray Pulsars (AXPs) and Soft Gamma-Ray Repeaters (SGRs). These fields have been extremely active in the last few years, both observationally and theoretically, driven partly by new X-ray data from Chandra, XMM-Newton and RXTE. At the same time, the Park...
متن کاملMagnetars and Pulsars: a Missing Link
There is growing evidence that soft gamma-ray repeaters (SGRs) and anomalous X-ray pulsars (AXPs) are isolated neutron stars with superstrong magnetic fields, i.e., magnetars, marking them a distinguished species from the conventional species of spindown-powered isolated neutron stars, i.e., radio pulsars. The current arguments in favor of the magnetar interpretation of SGR/AXP phenomenology wi...
متن کاملDo we see accreting magnetars in X-ray pulsars?
Strong magnetic field of accreting neutron stars (10 G) is hard to probe by Xray spectroscopy but can be indirectly inferred from spin-up/spin-down measurement in X-ray pulsars. The existing observations of slowly rotating X-ray pulsars are discussed. It is shown that magnetic fields of neutron stars derived from these observations (or lower limits in some cases) fall within the standard 10-10 ...
متن کاملDo magnetars glitch? : Timing irregularities in anomalous X-ray pulsars
We examine the timing history of several anomalous X-ray pulsars (AXPs), and find that they exhibit spin down irregularities statistically similar to those of radio pulsars. We propose that these irregularities are simply glitches like those of radio pulsars and fit glitching spin down solutions to the data available for 1E 2259+586, 1E 1048.1-5937 and 4U 0142+61. The inferred magnitude of the ...
متن کاملWave Modes in the Magnetospheres of Pulsars and Magnetars
We study the wave propagation modes in the relativistic streaming pair plasma of the magnetospheres of pulsars and magnetars, focusing on the effect of vacuum polarization. We show that the combined plasma and vacuum polarization effects give rise to a vacuum resonance, where “avoided mode crossing” occurs between the extraordinary mode and the (superluminous) ordinary mode. When a photon propa...
