Diffusion and pulsations in slowly rotating B stars
Published online by Cambridge University Press: 13 January 2006
Abstract
Diffusion in cool B stars of the main sequence has been shown to strongly affect opacities and convection in cool B stars of the main sequence. We show here that diffusion in B stars maintains or enhances the excitation ofpulsations in these stars. This result conflicts with observations as cool B starsthat show evidence of diffusion, the HgMn stars, are stable to the currentdetection level. We discuss possible implications of this discrepancy for the models.
