Gravitational Radiation from Accreting Millisecond Pulsars
Matthias Vigelius, Donald Payne, Andrew Melatos
It is widely assumed that the observed reduction of the magnetic field of millisecond pulsars can be connected to the accretion phase during which the pulsar is spun up by mass acc…
Gravitational radiation from pulsar glitches
C. A. van Eysden, A. Melatos
The nonaxisymmetric Ekman flow excited inside a neutron star following a rotational glitch is calculated analytically including stratification and compressibility. For the largest…
Collapse times of dipolar Bose-Einstein condensates
C. Ticknor, N. G. Parker, A. Melatos +3
We investigate the time taken for global collapse by a dipolar Bose-Einstein condensate. Two semi-analytical approaches and exact numerical integration of the mean-field dynamics a…
Does the accreting millisecond pulsar XTE J1814-338 precess?
C. T. Y. Chung, D. K. Galloway, A. Melatos
Precession in an accretion-powered pulsar is expected to produce characteristic variations in the pulse properties. Assuming surface intensity maps with one and two hotspots, we co…
A Cellular Automaton Model of Pulsar Glitches
L. Warszawski, A. Melatos
A cellular automaton model of pulsar glitches is described, based on the superfluid vortex unpinning paradigm. Recent analyses of pulsar glitch data suggest that glitches result fr…
Nonideal evolution of nonaxisymmetric, force-free magnetic fields in a magnetar
Alpha Mastrano, Andrew Melatos
Recent numerical magnetohydrodynamic calculations by Braithwaite and collaborators support the `fossil field' hypothesis regarding the origin of magnetic fields in compact stars an…
