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…
Milne-Eddington Solutions for Relativistic Plane-Parallel Flows
J. Fukue
Radiative transfer in a relativistic plane-parallel flow, e.g., an accretion disk wind, is examined in the fully special relativistic treatment. Under the assumption of a constant…
Observational Appearance of Black Hole Winds
J. Fukue, N. Sumitomo
We examine the observational appearance of an optically thick, spherically symmetric, relativistic wind (a black hole wind). In a relativistic flow, the apparent optical depth beco…
Observational Appearance of Relativistic, Spherically Symmetric Massive Winds
N. Sumitomo, S. Nishiyama, C. Akizuki +2
The photon mean free path in a relativistically moving medium becomes long in the down-stream direction while short in the up-stream direction. As a result, the observed optical de…
