4U 1538-52 in a Heartbeat: Broadband X-ray Spectral Properties from XMM-Newton and NuSTAR
C. M. Diez, S. Dupourqué, A. -L. Doherty +8
Galactic high-mass X-ray binaries (HMXBs) are important systems for studying accretion mechanisms onto compact objects and for investigating the complex stellar winds of massive st…
Time-Incremented Multiscale Evolution (TIME): A Code-Independent Method for Time-Domain 3D Hydrodynamics and its Application to Roche Lobe Overflow
David Dickson
Context. Many critical physical processes, such as Roche lobe overflow, strain modern simulation methods due to their durations and multidimensionality. Aims. We employ a novel met…
Quantifying Roche Lobe Overflow in the Formation of Merging Black Hole Binaries
David Dickson
We demonstrate a new methodology to model Roche lobe overflow (RLO) systems to unprecedented resolution simultaneously across the envelope, donor wind, tidal stream, and accretion…
Hydrodynamic 3D Simulation of Roche Lobe Overflow in High-mass X-Ray Binaries
David Dickson
While binary merger events have been an active area of study in both simulations and observational work, the formation channels by which a high-mass star extends from Roche lobe ov…
