| Abstract | |
In this work we explore the effect of binarity on the decretion disk of Be stars in order to explain their variability. To this aim, we performed smoothed particle hydrodynamics (SPH) simulations on Be binary systems, following the matter ejected isotropically from the equator of the Be star towards the base of an isothermal decretion disk. We let the system evolve long enough to be considered at steady state, and focus on the effect of viscosity for coplanar prograde binary orbits. The disk structure is found to be locked to the orbital phase and to exhibit a dependence on the azimuthal angle. Additionally, we present the first results from detailed non-local thermodynamic equilibrium (non-LTE) radiative transfer calculations of the disk structure computed with the SPH code. This is achieved by the use of the three-dimensional (3D) Monte Carlo code HDUST, which can produce predictions with respect to a series of observables. (AU) | |
