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…
The X-ray Variability and Luminosity Function of High Mass X-ray Binaries in the Dwarf Starburst Galaxy IC 10
Breanna A. Binder, Rosalie Lazarus, Mina Thoresen +2
We present an analysis of 235 ks of Chandra observations obtained over 19 years of the nearby dwarf starburst galaxy IC 10 in order to study the X-ray variability and X…
Observing Rayleigh-Taylor stable and unstable accretion through a Kalman filter analysis of X-ray pulsars in the Small Magellanic Cloud
Joseph O'Leary, Andrew Melatos, Tom Kimpson +5
Global, three-dimensional, magnetohydrodynamic simulations of Rayleigh-Taylor instabilities at the disk-magnetosphere boundary of rotating, magnetized, compact stellar objects reve…
Measuring the magnetic dipole moment and magnetospheric fluctuations of accretion-powered pulsars in the Small Magellanic Cloud with an unscented Kalman filter
Joseph O'Leary, Andrew Melatos, Tom Kimpson +5
Many accretion-powered pulsars rotate in magnetocentrifugal disequilibrium, spinning up or down secularly over multi-year intervals. The magnetic dipole moment of such systems…
Measuring the magnetic dipole moment and magnetospheric fluctuations of SXP 18.3 with a Kalman filter
J. O'Leary, A. Melatos, N. J. O'Neill +4
The magnetic dipole moment of an accretion-powered pulsar in magnetocentrifugal equilibrium cannot be inferred uniquely from time-averaged pulse period and aperiodic X-ray flux…
The First TESS Self-Lensing Pulses: Revisiting KIC 12254688
Nicholas M. Sorabella, Silas G. T. Laycock, Dimitris M. Christodoulou +1
We report the observations of two self-lensing pulses from KIC 12254688 in Transiting Exoplanet Survey Satellite (TESS) light curves. This system, containing a F2V star and white-d…
