Abstract: (arXiv)
We have computed theoretical models of circumstellar disks for the classical Be stars Dra, Psc, and Cyg. Models were constructed using a non-LTE radiative transfer code developed by \citet{sig07} which incorporates a number of improvements over previous treatments of the disk thermal structure, including a realistic chemical composition. Our models are constrained by direct comparison with long baseline optical interferometric observations of the H emitting regions and by contemporaneous H line profiles. Detailed comparisons of our predictions with H interferometry and spectroscopy place very tight constraints on the density distributions for these circumstellar disks.References(27)
