Testing the effects of opacity and the chemical mixture on the excitation of pulsations in B stars of the Magellanic Clouds

S. Salmon, J. Montalbán, T. Morel +3

The B-type pulsators known as βCephei and Slowly Pulsating B (SPB) stars present pulsations driven by the κmechanism, which operates thanks to an opacity bump due to the iron group…
