SPH simulations of accretion flow via Roche lobe overflow and via mass transfer from Be disk
Kimitake Hayasaki, Atsuo T. Okazaki, James. R. Murray
We compare the accretion flow onto the neutron star induced by Roche lobe overflow with that by the overflow from the Be disk, in a zero eccentricity, short period binary with the…
Long-term evolution of accretion disks around the neutron star in Be/X-ray binaries
Kimitake Hayasaki, Atsuo T. Okazaki
we study the long-term evolution of the accretion disk around the neutron star in Be/X-ray binaries. We confirm the earlier result by Hayasaki & Okazaki (2004) that the disk evolve…
One-armed spiral structure of accretion discs induced by a phase-dependent mass transfer in Be/X-ray binaries
Kimitake Hayasaki, Atsuo T. Okazaki
We study non-axisymmetric structure of accretion discs in Be/X-ray binaries, performing three dimensional Smoothed Particle Hydrodynamics simulations for a coplanar system with a s…
