Electrodynamics of pulsar magnetospheres
I review the theoretical understanding of the global structure of pulsar magnetospheres concentrating on recent progress in force-free electrodynamics and first-principles simulations of magnetospheres.
متن کاملPulsar electrodynamics: a time-dependent view
Pulsar spindown forms a reliable yet enigmatic prototype for the energy loss processes in many astrophysical objects including accretion disks and back holes. In this paper we review the physics of pulsar magnetospheres, concentrating on recent developmen ts in force-free modeling of the magnetospheric structure. In particular, we discuss a new method for solving the equations of time-dependent...
متن کاملM. Kramer, N. Wex, and R. Wielebinski, eds. Pulsar Electrodynamics
First I emphasize the magnetospheric loop current system induced by the wind activity. Next, I address the formation of the fieldaligned electric field. An interesting aspect is the reaction of the inner magnetosphere to an induced current. In the traditional outer gap, the current running through the gap is all carried by the particles created in the gap. However, if external current-carrying ...
متن کاملSpacetime metric from linear electrodynamics II
Following Kottler, É.Cartan, and van Dantzig, we formulate the Maxwell equations in a metric independent form in terms of the field strength F = (E,B) and the excitation H = (D,H). We assume a linear constitutive law between H and F . First we split off a pseudo-scalar (axion) field from the constitutive tensor; its remaining 20 components can be used to define a duality operator # for 2-forms....
متن کاملPulsar bow - shock nebulae II . Hydrodynamical Simulation
We present hydrodynamical simulations, using a 2-D two component model (ambient medium and pulsar wind have different specific heat ratios), of bow shocks in a representative regime for pulsar wind driven bow-shock nebulae. We also investigate the behaviour of a passive toroidal magnetic field wound around the pulsar velocity direction. Moreover we estimate the opacity of the bow-shock to penet...
