WHAT CAN 3D SIMULATIONS TELL US ABOUT MASS
ACCRETION IN X-RAY BINARIES?
Wind Accretion in high-mass XRBs (Vela X-1)
- How does the mass accretion rate vary with system parameters? How does the
angular momentum accretion rate vary with time? How does the circumstellar gas affect
the observed X-ray flux?
- Roche lobe overflow in high-mass XRBs (LMC X-4)
- How big is the disk? How does the system evolve as the mass accretion rate increases?
What is the source of circumstellar gas?
- Roche lobe overflow in low-mass XRBs (Sco X-1)
- How does the tidal stream merge with the disk? Does it overflow the disk edge?
Is there a bulge at the point of impact?
