High-energy observations of PSR B1259-63/LS 2883 through the 2014 periastron passage: connecting X-rays to the GeV flare
P. H. T. Tam, K. L. Li, J. Takata +3
The binary system PSR B1259-63/LS 2883 is well sampled in radio, X-rays, and TeV gamma-rays, and shows orbital phase-dependent variability in these frequencies. The first detection…
Radiation-Driven Warping of Circumbinary Disks Around Eccentric Young Star Binaries
Kimitake Hayasaki, Bong Won Sohn, Atsuo T. Okazaki +3
We study a warping instability of a geometrically thin, non-self-gravitating, circumbinary disk around young binary stars on an eccentric orbit. Such a disk is subject to both the…
Warped Circumbinary Disks in Active Galactic Nuclei
Kimitake Hayasaki, Bong Won Sohn, Atsuo T. Okazaki +3
We study a warping instability of a geometrically thin, non-self-gravitating disk surrounding binary supermassive black holes on a circular orbit. Such a circumbinary disk is subje…
Sudden End of X-Ray Outbursts around Periastron of Circinus X-1 Observed with MAXI
Kazumi Asai, Tatehiro Mihara, Masaru Matsuoka +5
MAXI/GSC observed 21 outbursts from Circinus X-1 between 2009 August and 2013 December. Although 14 outbursts showed ordinary gradual decays, in 7 outbursts we found sudden luminos…
3D Dynamical Modeling of Wind Accretion in Cyg X-3
Atsuo T. Okazaki, Christopher M. P. Russell
Cyg X-3 is a high mass X-ray binary consisting of a Wolf-Rayet star and a compact object in a very short orbital period of 4.8h. The only confirmed microquasar with high energy gam…
3D Hydrodynamic & Radiative Transfer Models of X-ray Emission from Colliding Wind Binaries
Christopher M. P. Russell, Atsuo T. Okazaki, Stanley P. Owocki +3
Colliding wind binaries (CWBs) are unique laboratories for X-ray astrophysics. The massive stars in these systems possess powerful stellar winds with speeds up to 3000 km s$^…
