Relativistic Variable Eddington Factor in a Relativistic Plane-Parallel Flow
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 the comoving frame. Namely, the comoving observer sees radiation coming from a closed surface where the optical depth measured from the observer is unity; such a surface is called a one-tau photo-oval. In general, the...
متن کاملMilne-Eddington Solutions for Relativistic Plane-Parallel Flows
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 flow speed, for the relativistically moving atmosphere we analytically obtain generalized Milne-Eddington solutions of radiative moment equations; the radiation energy density, the radiative flux, and the radiation pr...
متن کاملVariable Eddington Factor in a Relativistic Plane-Parallel Flow
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 velocity gradient, there also exists a density gradient. The comoving observer sees radiation coming from a closed surface where the optical depth measured from the observer is unity. Such a surface, called a one-tau pho...
متن کاملVelocity-Dependent Eddington Factor in Relativistic Radiative Flow
We propose a variable Eddington factor, depending on the flow velocity v, for the relativistic radiative flow, whose velocity becomes of the order of the speed of light. When the gaseous flow is radiatively accelerated up to the relativistic regime, the velocity gradient becomes very large in the direction of the flow. As a result, the radiative diffusion may become anisotropic in the comoving ...
متن کاملRelativistic Radiative Transfer for Spherical Flows
We present a new complete set of Lagrangian relativistic hydrodynamical equations describing the transfer of energy and momentum between a standard fluid and a radiation fluid in a general non-stationary spherical flow. The new set of equations has been derived for a particular application to the study of the cosmological Quark–Hadron transition but can also be used in other contexts.
