Magnetospheres of neutron stars are anchored in the rigid crust and can be twisted by sudden crustal motions (“starquakes”). The twisted magnetosphere does not remain static and gradually untwists, dissipating magnetic energy and producing radiation. The equation describing this evolution is derived, and its solutions are presented. Two distinct regions coexist in untwisting magnetospheres: a potential region where ∇ ×  B = 0 (“cavity”) and a current-carrying bundle of field lines with ∇ ×  B… 
DYNAMICS OF STRONGLY TWISTED RELATIVISTIC MAGNETOSPHERES
Magnetar magnetospheres are believed to be strongly twisted due to shearing of the stellar crust by internal magnetic stresses. We present time-dependent axisymmetric simulations showing in detail
Magnetically driven crustquakes in neutron stars
Crustquake events may be connected with both rapid spin-up ‘glitches’ within the regular slowdown of neutron stars, and high-energy magnetar flares. We argue that magnetic-field decay builds up
MAGNETAR FIELD EVOLUTION AND CRUSTAL PLASTICITY
The activity of magnetars is believed to be powered by colossal magnetic energy reservoirs. We sketch an evolutionary picture in which internal field evolution in magnetars generates a twisted
TWIST-INDUCED MAGNETOSPHERE RECONFIGURATION FOR INTERMITTENT PULSARS
We propose that the magnetosphere reconfiguration induced by magnetic twists in the closed field line region can account for the mode switching of intermittent pulsars. We carefully investigate the
MAGNETAR GIANT FLARES-FLUX ROPE ERUPTIONS IN MULTIPOLAR MAGNETOSPHERIC MAGNETIC FIELDS
We address a primary question regarding the physical mechanism that triggers the energy release and initiates the onset of eruptions in the magnetar magnetosphere. Self-consistent stationary,
Particle-in-Cell Simulations of the Twisted Magnetospheres of Magnetars. I.
The magnetospheres of magnetars are believed to be filled with electron–positron plasma generated by electric discharge. We present a first numerical experiment demonstrating this process in an
TWISTING, RECONNECTING MAGNETOSPHERES AND MAGNETAR SPINDOWN
We present the first simulations of evolving, strongly twisted magnetar magnetospheres. Slow shearing of the magnetar crust is seen to lead to a series of magnetospheric expansion and reconnection
Global Crustal Dynamics of Magnetars in Relation to Their Bright X-Ray Outbursts
This paper considers the yielding response of a neutron star crust to smooth, unbalanced Maxwell stresses imposed at the core–crust boundary, and the coupling of the dynamic crust to the external
Coherent Radio Emission from a Twisted Magnetosphere after a Magnetar-quake
Magnetars are a class of highly magnetized, slowly rotating neutron stars, only a small fraction of which exhibit radio emission. We propose that the coherent radio curvature emission is generated by
Instability of twisted magnetar magnetospheres
We present 3D force-free electrodynamics simulations of magnetar magnetospheres that demonstrate the instability of certain degenerate, high energy equilibrium solutions of the Grad–Shafranov

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

TLDR
The reappearance of persistent X-ray emission from SGR 1900+14 within one day of the August 27 event provides strong evidence that the persistent emission is not powered by accretion, and is attributed to continued particle heating in the active region of that outburst.
