The Meissner effect in neutron stars
S. K. Lander
We present the first model aimed at understanding how the Meissner effect in a young neutron star affects its macroscopic magnetic field. In this model, field expulsion occurs on a…
Signatures of magnetic flux expulsion from neutron star cores
S. K. Lander, K. N. Gourgouliatos, Z. Wadiasingh +1
Shortly after a neutron star is born, the protons in its core begin to form a superconductor. In terrestrial materials, the hallmark of superconductivity is an associated expulsion…
Twisted magnetar magnetospheres
D. Ntotsikas, K. N. Gourgouliatos, I. Contopoulos +1
Magnetar magnetospheres are strongly twisted, and are able to power sudden energetic events through the rapid release of stored electromagnetic energy. In this paper, we investigat…
The game of life on a magnetar crust: from -ray flares to FRBs
S. K. Lander
This paper presents a model to unify the diverse range of magnetar activity, through the building and release of elastic stress from the crust. A cellular automaton drives both loc…
Pulse Peak Migration during the Outburst Decay of the Magnetar SGR 1830-0645: Crustal Motion and Magnetospheric Untwisting
G. Younes, S. K. Lander, M. G. Baring +12
Magnetars, isolated neutron stars with magnetic field strengths typically ~G, exhibit distinctive months-long outburst epochs during which strong evolution of soft…
Axisymmetric magneto-plastic evolution of neutron-star crusts
Konstantinos N. Gourgouliatos, Samuel K. Lander
Magnetic field evolution in neutron-star crusts is driven by the Hall effect and Ohmic dissipation, for as long as the crust is sufficiently strong to absorb Maxwell stresses exert…
