Electromagnetic spin down of a transient accreting millisecond pulsar during quiescence
Andrew Melatos, Alpha Mastrano
The measured spin-down rates in quiescence of the transient accreting millisecond pulsars IGR J00291+5934, XTE J1751-305, SAX J1808.4-3658, and Swift J1756.9-2508 have been used to…
Testing modified gravity and no-hair relations for the Kerr-Newman metric through quasi-periodic oscillations of galactic microquasars
Arthur George Suvorov, Andrew Melatos
We construct multipole moments for stationary, asymptotically flat, spacetime solutions to higher-order curvature theories of gravity. The moments are defined using technique…
Hydrodynamic simulations of pulsar glitch recovery
G. Howitt, B. Haskell, A. Melatos
Glitches are sudden jumps in the spin frequency of pulsars believed to originate in the superfluid interior of neutron stars. Superfluid flow in a model neutron star is simulated b…
Spin paramagnetic deformation of a neutron star
A. G. Suvorov, A. Mastrano, A. Melatos
Quantum mechanical corrections to the hydromagnetic force balance equation, derived from the microscopic Schrödinger-Pauli theory of quantum plasmas, modify the equilibrium structu…
Pinned vortex hopping in a neutron star crust
Brynmor Haskell, Andrew Melatos
The motion of superfluid vortices in a neutron star crust is at the heart of most theories of pulsar glitches. Pinning of vortices to ions can decouple the superfluid from the crus…
Interpreting the AXP 1E 2259+586 antiglitch as a change in internal magnetization
Alpha Mastrano, Arthur George Suvorov, Andrew Melatos
The sudden spin-down event ('anti-glitch') observed in AXP 1E 2259+586 on 2012 April 21 was arguably caused by a decay of its internal toroidal magnetic field component, which turn…
