Radiatively-driven black-hole winds revisited

Ryoya Yamamoto, Jun Fukue

We examine general relativistic radiatively-driven spherical winds, using the basic equations for relativistic radiation hydrodynamics under the moment formalism. Moment equations…

Optical Light Curves of Luminous Eclipsing Black Hole X-ray Binaries

Ken-ya Watarai, Jun Fukue

We examine optical V-band light curves in luminous eclipsing black hole X-ray binaries, using a supercritical accretion/outflow model that is more realistic than the formerly used…

Relativistic Spectra of Hot Black-Hole Winds

Naoko Sumitomo, Hideki Saito, Jun Fukue +1

We examine hybrid thermal-nonthermal synchrotron spectra from a spherically symmetric, optically-thin wind, taking into account the relativistic effect. In the relativistic flow fr…

Relativistic Variable Eddington Factor in a Relativistic Plane-Parallel Flow

J. Fukue

We examine the behavior of the variable Eddington factor for a relativistically moving radiative flow in the vertical direction. We adopt the "one-tau photo-oval" approximation in…

Variable Eddington Factor in a Relativistic Plane-Parallel Flow

J. Fukue

We examine the Eddington factor in an optically thick, relativistic flow accelerating in the vertical direction. % When the gaseous flow is radiatively accelerated and there is a v…

Relativistic Variable Eddington Factor

J. Fukue

We analytically derive a relativistic variable Eddington factor in the relativistic radiative flow, and found that the Eddington factor depends on the {\it velocity gradient} as we…
