| Abstract: |
We have applied a nonadiabatic pulsation analysis including rotation effects to evolutionary models of 22MSolar which pass around the location of ζ Oph in the HR diagram. Several pulsations are excited by the κ-mechanism at the Fe-bump of opacity. The main MOST frequency of 5.181 c/d is consistent with either quasi-radial fundamental or first-overtone mode. In both cases, frequencies of the excited low surface-order (even) modes seem to reproduce most of the observed frequencies with high-amplitude signals. |
