Eclipsing light curves for accretion flows around a rotating black hole and atmospheric effects of the companion star
Rohta Takahashi, Ken-Ya Watarai
We calculate eclipsing light curves for accretion flows around a rotating black hole taking into account the atmospheric effects of the companion star. In the cases of no atmospher…
Hot Disk Corona and Magnetic Turbulence in Radio-Quiet Active Galactic Nuclei: Observational Constraints
Jian-Min Wang, Ken-Ya Watarai, Shin Mineshige
We compile a sample consisting of 56 radio-quiet active galactic nuclei so as to investigate statistical properties of hot corona of accretion disks from {\em ASCA} observations. T…
Accretion Disk Spectra of the Ultra-luminous X-ray Sources in Nearby Spiral Galaxies and Galactic Superluminal Jet Sources
Ken Ebisawa, Piotr Zycki, Aya Kubota +2
Ultra-luminous Compact X-ray Sources (ULXs) in nearby spiral galaxies and Galactic superluminal jet sources share the common spectral characteristic that they have unusually high d…
Model for Relaxation Oscillations of Luminous Accretion Disk in GRS1915+105: Variable Inner Edge
Ken-ya Watarai, Shin Mineshige
To understand the bursting behavior of the microquasar GRS 1915+105, we calculate time evolution of a luminous, optically thick accretion disk around a stellar mass black hole unde…
Spectral Energy Distribution in Supercritical Disk Accretion Flows through Photon-trapping Effects
K. Ohsuga, S. Mineshige, K. Watarai
We investigate the spectral energy distribution (SED) of the supercritical disk accretion flows around black holes by solving the multi-frequency zeroth moment equation of the radi…
