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 multiye…

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…
