Spin wandering of an accreting neutron star near torque balance: implications for gravitational wave searches
Andrew Melatos
Torque balance between gravitational radiation reaction and magnetocentrifugal accretion is one reason why accreting neutron stars rotate slower than centrifugal break-up. Random p…
Discovering pulsars in compact binaries with a hidden Markov model
Joseph O'Leary, Liam Dunn, Andrew Melatos
Discovering radio pulsars in compact binaries, whose orbital periods satisfy , is computationally challenging, because the time-depend…
Is there a retrograde accretion disk around 4U 162667? Tracking torque reversals with a state-space model
Joseph O'Leary, Andrew Melatos, Tom Kimpson +5
X-ray timing studies of the persistent, Galactic, accretion-powered pulsar 4U 162667 reveal torque reversals, during which the pulse frequency alternates between multiyea…
Measuring the crust-superfluid coupling time-scale for 105 UTMOST pulsars with a Kalman filter
Wenhao Dong, Andrew Melatos, Nicholas J. O'Neill +2
Crust-superfluid coupling plays an important role in neutron star rotation, particularly with respect to timing noise and glitches. Here, we present new timing-noise-based estimate…
Quadrupole Moment of a Magnetically Confined Mountain on an Accreting Neutron Star in General Relativity
Pedro Henrique Barboza Rossetto, Jörg Frauendiener, Andrew Melatos
General relativistic corrections are calculated for the quadrupole moment of a magnetically confined mountain on an accreting neutron star. The hydromagnetic structure of the mount…
Magnetic dynamo caused by axions in neutron stars
Filippo Anzuini, José A. Pons, Antonio Gómez-Bañón +3
The coupling between axions and photons modifies Maxwell's equations, introducing a dynamo term in the magnetic induction equation. In neutron stars, for critical values of the axi…
Stability of interlinked neutron vortex and proton flux tube arrays in a neutron star: equilibrium configurations
L. V. Drummond, A. Melatos
Three-dimensional, Gross-Pitaevskii equation (GPE) simulations are presented of the interaction between neutron superfluid vortices and proton superconductor flux tubes in a rotati…
