Kappa-Mechanism Excitation of Retrograde Mixed Modes in B-Type Stars
Bartol Research Institute, University of Delaware
The stability of retrograde mixed modes in rotating B-type stars is investigated. It is found that these modes are susceptible to kappa-mechanism excitation, due to the iron opacity bump at log T ~ 5.3. The findings are discussed in the context of the pulsation of SPB and Be stars.
