Non-linear magnetic field decay in neutron stars Theory and observations
Ulrich Geppert,M. Rheinhardt +1 more
TL;DR: In this paper, it was shown that the magnetic field decay in neutron stars may proceed in a non-linear way during a certain episode of the neutron star's life, and that the Hall-drift dominates the field evolution in the crust and/or the superfluid core of neutron stars.
Journal ArticleDOI
Accretion and evolution of the neutron star magnetic field
V. Urpin,Ulrich Geppert +1 more
Journal ArticleDOI
Spot-like structures of neutron star surface magnetic fields
TL;DR: In this paper, it is shown that due to a Hall-drift induced instability, poloidal magnetic field structures can be generated from strong subsurface toroidal fields, which are the result of either a dynamo or a thermoelectric instability acting at early times of a neutron star's life.
Journal ArticleDOI
Creation of magnetic spots at the neutron star surface
TL;DR: In this paper, it was shown that magnetic spots can be created on a time-scale of 104 yr with magnetic field strengths ≳5 × 1013 G, provided almost the whole magnetic energy is stored in its toroidal component, and that the conductivity in the inner crust is not too large.
Journal ArticleDOI
Evolution of neutron stars in high-mass X-ray binaries
TL;DR: In this paper, the evolution of neutron stars during the X-ray phase of high-mass binaries was considered and it was shown that strong wind from the companion can significantly influence the magnetic and spin behavior of a neutron star even during the main-sequence life of the companion.
