| Abstract: |
In the last years, the viscous decretion disk model (VDDM) came out as the
only model capable of reproducing the observed properties of Be
stars. However, this model is still not straightforward to use, particularly
because the influence of the stellar mass loss rate on the disk is not well
understood. Hydrodynamic simulations coupled with radiative tranfer codes now
allow modeling the disk evolution. In this contribution, we discuss some VDDM
predictions for the density of the disk for some simple reference cases and
their consequences on photometric observables. We show how these predictions
can reproduce observations, focusing, in particular, on the analysis of the Be
star 28 CMa. |
