Description

We describe our own global (unified) hydrodynamical models of expanding atmospheres of hot stars. The models solve hydrodynamic, kinetic equilibrium (also known as NLTE), and comoving-frame (CMF) radiative transfer equations consistently from the (nearly) hydrostatic photosphere to the supersonic wind. The model input parameters are the stellar effective temperature, radius, mass, and metalicity. For these stellar parameters, our code predicts the photosphere and wind structure and in particular the wind mass-loss rate and terminal velocity. The photospheric emergent flux and thermal structure nicely agree with the TLUSTY model atmospheres.
