This paper explores small-scale departures from force-free electrodynamics around a rotating neutron star, extending our treatment of resistive instability in a quantizing magnetic field. A secondary, Cerenkov instability is identified: relativistic particles flowing through thin current sheets excite propagating charge perturbations that are localized near the sheets. Growth is rapid at wavenumbers below the inverse ambient skin depth k p,ex. Small-scale Alfvénic wavepackets are promising…

Radiative or two-stream instability as a source for pulsar radio emission

The origin of the radio wave emission in pulsars has been related to the growth of either radiative or two-stream instability in the open magnetosphere, above the neutron star magnetic poles. The

Dissipation of the striped pulsar wind

Rapidly rotating neutron stars blow a relativistic, magnetized wind mainly composed of electron-positron pairs. The free expansion of the wind terminates far from the neutron star where a weakly

The Spark-associated Soliton Model for Pulsar Radio Emission

We propose a new, self-consistent theory of coherent pulsar radio emission based on the nonstationary sparking model of Ruderman & Sutherland, modified by Gil & Sendyk. The polar cap is populated by

Coherent Emission in Pulsars, Magnetars, and Fast Radio Bursts: Reconnection-driven Free Electron Laser

We develop a model of the generation of coherent radio emission in the Crab pulsar, magnetars, and fast radio bursts (FRBs). Emission is produced by a reconnection-generated beam of particles via a

Electrodynamics of Magnetars. III. Pair Creation Processes in an Ultrastrong Magnetic Field and Particle Heating in a Dynamic Magnetosphere

We first examine the QED processes that create electron-positron pairs in magnetic fields approaching and exceeding 1014 G. The formation of free and bound pairs is addressed, and the importance of

Corona of Magnetars

We develop a theoretical model that explains the formation of hot coronae around strongly magnetized neutron stars—magnetars. The starquakes of a magnetar shear its external magnetic field, which

On the mean profiles of radio pulsars – I. Theory of propagation effects

We study the influence of propagation effects on the mean profiles of radio pulsars using the method of wave propagation in inhomogeneous media described by Kravtsov & Orlov. This approach allows us

Nonlinear explosive magnetic reconnection in a collisionless system

The debate surrounding fast magnetic energy dissipation by magnetic reconnection has remained a fundamental topic in the plasma universe, not only in the Earth’s magnetosphere but in astrophysical

Excitation of Alfvén waves and pulsar radio emission

We analyse mechanisms of the excitation of Alfven waves in pulsar magnetospheres as a possible source of pulsar radio emission generation. We find that Cherenkov excitation of obliquely propagating
