We have computed radiative equilibrium models for the gas in the circumstellar envelope surrounding the hot, classical Be star γ Cassiopeiae. This calculation is performed using a code that incorporates a number of improvements over previous treatments of the disk's thermal structure by Millar & Marlborough and Jones et al.; most importantly, heating and cooling rates are computed with atomic models for H, He, CNO, Mg, Si, Ca, and Fe and their relevant ions. Thus, for the first time, the… Expand
