Resumo

We present self-consistent solutions for the disk structure of classical Be stars. Our disk model is hydrostatically supported in the vertical direction and the radial structure is governed by viscosity (a-disks). We perform 3-D NLTE Monte Carlo simulations to calculate simultaneously both the equilibrium temperature and Hydrogen level populations and to solve self-consistently for the density structure of the disk. We discuss the general properties of the solution for the disk structure and test our model against observations of delta Scorpii. Our results confirm that a viscous decretion disk model is consistent with these observations. (AU)
