Nonaxisymmetric Hall instability: A key to understanding magnetars (2019)
Journal Article
Gourgouliatos, K., & Pons, J. A. (2019). Nonaxisymmetric Hall instability: A key to understanding magnetars. Physical Review Research, 1(3), Article 032049(R). https://doi.org/10.1103/physrevresearch.1.032049

It is generally accepted that the nonlinear, dynamical evolution of magnetic fields in the interior of neutron stars plays a key role in the explanation of the observed phenomenology. Understanding the transfer of energy between toroidal and poloidal... Read More about Nonaxisymmetric Hall instability: A key to understanding magnetars.

Magnetic inhibition of centrifugal instability (2019)
Journal Article
Komissarov, S. S., Gourgouliatos, K. N., & Matsumoto, J. (2019). Magnetic inhibition of centrifugal instability. Monthly Notices of the Royal Astronomical Society, 488(3), 4061-4073. https://doi.org/10.1093/mnras/stz1973

Recently, it was shown that the centrifugal instability may be important in the dynamics of astrophysical jets undergoing reconfinement by external pressure. However, these studies were limited to the case of unmagnetized flows. Here, we explore the... Read More about Magnetic inhibition of centrifugal instability.

Current closure through the neutron star crust (2019)
Journal Article
Karageorgopoulos, V., Gourgouliatos, K., & Contopoulos, I. (2019). Current closure through the neutron star crust. Monthly Notices of the Royal Astronomical Society, 487(3), 3333-3341. https://doi.org/10.1093/mnras/stz1507

Force-free pulsar magnetospheres develop a large-scale poloidal electric current circuit that flows along open magnetic field lines from the neutron star to the termination shock. The electric current closes through the interior of the neutron star w... Read More about Current closure through the neutron star crust.

Magnetic-field evolution in a plastically failing neutron-star crust (2019)
Journal Article
Lander, S., & Gourgouliatos, K. (2019). Magnetic-field evolution in a plastically failing neutron-star crust. Monthly Notices of the Royal Astronomical Society, 486(3), 4130-4143. https://doi.org/10.1093/mnras/stz1042

Under normal conditions in a neutron-star (NS) crust, ions are locked in place in the crustal lattice and only electrons are mobile, and magnetic-field evolution is thus directly related to the electron velocity. The evolution, however, builds magnet... Read More about Magnetic-field evolution in a plastically failing neutron-star crust.
