The accretion regime of LS 5039: 3-D SPH simulations
A. T. Okazaki, G. E. Romero, S. P. Owocki
LS 5039 is a TeV gamma-ray binary with extended radio emission. It consists of a compact object in the mildly eccentric (e=0.35), 3.9-day orbit around a massive O star. The nature…
Accretion vs colliding wind models for the gamma-ray binary LS I +61 303: an assessment
G. E. Romero, A. T. Okazaki, M. Orellana +1
LS I +61 303 is a puzzling Be/X-ray binary with variable gamma-ray emission at up TeV energies. The nature of the compact object and the origin of the high-energy emission are uncl…
Accretion onto the neutron star in Be/X-ray binaries
Kimitake Hayasaki, Atsuo. T. Okazaki
We study accretion onto the neutron star in Be/X-ray binaries, using a 3D SPH code and the data imported from a high resolution simulation by Okazaki et al.\ (2002) for a coplanar…
The X-ray outbursts of Be/X-ray transients
Ignacio Negueruela, Atsuo T. Okazaki
We present a new scenario for the behaviour of Be/X-ray binaries based on long-term multiwavelength monitoring and the decretion disc model. The circumstellar discs of the primarie…
