This work explores a Pulsationally Driven Orbital Mass Ejection (PDOME) model for the launching of Classical Be star disks. Under this model, a combination of rapid rotation and non-radial pulsation modes contribute to placing material into the circumstellar environment. Several varieties of non-radial pulsation modes, characterized by their propagation direction and the relative phase of their velocity and density perturbations, are considered. As well, the orbital stability of material launched by such a mechanism is investigated.

    Adding viscous shear heating to Ae disk models makes Hα emission much easier to produce for spectral types A2 and cooler, and this dependence is proposed as a new way to measure the disk viscosity parameter α, though ...
