Magnetars versus Radio Pulsars: MHD Stability in Newborn Highly Magnetized Neutron Stars
We study the stability/establishment of dipolar magnetostatic equilibrium configurations in new–born neutron stars (NSs) in dependence on the rotational velocity Ω and on the initial angle α between rotation and magnetic axis.The NS is modeled as a sphere of a highly magnetized (B ∼ 10G) incompressible fluid of uniform density which rotates rigidly. For the initial dipolar background magnetic f...
متن کاملRotation-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 کاملRadio Emission from Magnetars
We discuss properties of the expected radio emission from Soft Gamma-ray Repeaters (SGRs) during their bursting activity in the framework of the model of Thompson, Lyutikov and Kulkarni (2002), in which the high energy emission is powered by the dissipation of super-strong magnetic fields in the magnetospheres through reconnection-type events. Drawing on analogies with Solar flares we predict t...
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 ...
