Non-rigid precession of magnetic stars
S. K. Lander, D. I. Jones
Stars are, generically, rotating and magnetised objects with a misalignment between their magnetic and rotation axes. Since a magnetic field induces a permanent distortion to its h…
Developing a model for neutron star oscillations following starquakes
L. Keer, D. I. Jones
Glitches -- sudden increases in spin rate -- are observed in many pulsars. One mechanism advanced to explain glitches in the youngest pulsars is that they are caused by a starquake…
Ambipolar diffusion in superfluid neutron stars
K. Glampedakis, D. I. Jones, L. Samuelsson
In this paper we reconsider the problem of magnetic field diffusion in neutron star cores. We model the star as consisting of a mixture of neutrons, protons and electrons, and allo…
Oscillations and instabilities in neutron stars with poloidal magnetic fields
S. K. Lander, D. I. Jones
We study the time evolution of non-axisymmetric linear perturbations of a rotating magnetised neutron star, whose magnetic field is multipolar and purely poloidal. The background s…
Instabilities in neutron stars with toroidal magnetic fields
S. K. Lander, D. I. Jones
We study oscillations and instabilities of magnetised neutron stars, by numerical time-evolution of linear perturbations of the system. The background stars are stationary eq…
Implications of magnetar non-precession
K. Glampedakis, D. I. Jones
The objects known as anomalous X-ray pulsars and soft gamma repeaters are commonly identified with magnetars, neutron stars with ultrastrong magnetic fields. The rotational history…
Oscillations of rotating magnetised neutron stars with purely toroidal magnetic fields
S. K. Lander, D. I. Jones, A. Passamonti
We investigate the oscillation spectrum of rotating Newtonian neutron stars endowed with purely toroidal magnetic fields, using a time evolution code to evolve linear perturbations…
Magnetic fields in axisymmetric neutron stars
S. K. Lander, D. I. Jones
We derive general equations for axisymmetric Newtonian MHD and use these as the basis of a code for calculating equilibrium configurations of rotating magnetised neutron stars in a…
