Scientific paper

We investigate the dynamics of radiatively driven, optically thick outflow in this second of two papers addressing the observable properties of supercritical winds. When the sonic radius of the flow is well within the trapping radius, a simple relation links the mass-loss rate, the position of the sonic point, and the observed luminosity (which is always in excess of the Eddington limit). The variation of the wind velocity deep within the flow is determined by numerically solving the relativistic, adiabatic version of Bernoulli's equation, and the result is incorporated into the radiative transfer formalism of the first paper to calculate the radiative properties of supercritical winds for a variety of astrophysical systems.
