| Abstract: |
The eclipsing spectroscopic binary V471 Tau has a compact DA component that has been observed to pulsate with multimode, low amplitude oscillations. Three models are tested with different masses (M/Solar mass = 0.6, 0.8, 1.0) against nonradial instability. The models are derived from an evolutionary track calculated by Iben. The results confirm that the pulsations are driven by the kappa and gamma mechanisms operating in the ionization zones of carbon and oxygen. |
